Bus Rapid Transit (BRT)
In 2015, The Bus Rapid Transit (sustainable bus transportation systems) was introduced with a mission to battle against (-) decreased users that resulted in (-) reduced services, (-) poorer services, (-) increased complaints, and an increase in  users that led to decreased direct-routes to suburbs, Furumachi, and Niigata Station. 

Niigata Bus Crisis Post-Covid Pandemic
In 2020, The BRT Review found out that Niigata-ken had a high level of dissatisfaction with the new BRT. Post-Pandemic Covid-19 the number of bus users had a huge-drop and it triggered a "Niigata Bus Crisis". The Government responded with a Promotion Team (Urban Development x Bus Transportation Team w/Kanagawa Chuo Kotsu)

The Bus Improvement Project (3-year. expired 2023): easy-to-understand, easy-to-use, and highly satisfying experience. This resulted in: windbreak panels, waiting rooms at Aoyama junction, and an additional roof for the bus stop in front of Media Ship.

Ongoing Issues: Two issues were driver shortages and maintaining the total mileage, it became clear that "it will be difficult to further increase the number of direct buses", "the planned purchase of four additional articulated buses will be postponed," and "the situation is not conducive to discussing the establishment of dedicated running lanes."

Niigata Station Area Development Project: Niigata Station for the first time was the Bus-Base with a bus terminal below the station, connecting Local-North and Local-South bus routes. Then there is the Long-Distance Terminal "Busta Niigata" (Japan National Project) 

Niigata Bandai Bus Festival:

Niigata Circle-City Bus Line Revitalization Project: The revitalization of "Niigata 2km" has to flexibly utilize demand-responsive transportation that takes into account the characteristics of the area, not only on the main routes but also in the suburbs, to create an environment where everyone can move around easily.

(-) Lower Ridership is Private Transportation vs Public Transportation
Researching the reasons behind lower bus ridership in Niigata. Looking at various factors that could contribute to this issue include a declining and aging population, a high rate of private car ownership, and various issues within the public transport system itself. It appears that Niigata's urban sprawl also plays a role, making car use more prevalent. Niigata's metro area population is indeed declining, with a consistent annual decrease. This aligns with broader trends in Japan where rural populations are aging and shrinking, impacting public transport sustainability. 

Over reliance on private cars, with nearly one car per person in 2002, this trend of increasing car ownership continues despite population decline. The city's expansive geographical area further contributes to this car dependency, shutting down rail lines contributes to it too. Despite the availability of rail, bus, and taxi services, private cars remain the predominant mode of transportation for residents and visitors alike. This reliance on personal vehicles exists against a backdrop of consistently declining bus ridership, a trend that has prompted city officials to actively explore the development of new public transportation systems. The overarching aim of these initiatives is to attract more riders and, in doing so, catalyze the revitalization of the city's central business districts, such as Furumachi. 

The challenges observed in Niigata are not isolated, but rather reflect broader trends affecting regional public transport systems across Japan, particularly in the face of evolving demographic and socio-economic conditions. This report delves into the multifaceted factors contributing to Niigata's lower bus ridership, providing a detailed analysis of these complex issues.   

Population Decline and Rapid Aging

Niigata's metro area population has been in a consistent state of decline, decreasing from approximately 812,000 in 2011 to an estimated 794,000 in 2025. This represents a steady annual decline of roughly 0.25% in recent years. This demographic contraction is not unique to Niigata, but rather a pervasive trend observed across many Japanese cities, including even some major metropolitan areas.   

A critical exacerbating factor is the rapid aging of the population. In older town areas within Chuo-ku, such as Shimo-machi, elderly citizens increasingly depend on buses for essential trips to medical facilities and supermarkets. Japan as a nation is experiencing profound demographic shifts, with projections indicating that by 2050, a third of its population will be aged 65 or older. Rural areas, including parts of Niigata, are aging at an even faster rate than the national average. This demographic transformation implies a lengthening period during which individuals' day-to-day mobility may become restricted, thereby increasing the necessity for alternatives to private vehicle operation.   

The combination of an overall population decline and a rapidly aging demographic directly shrinks the potential ridership base for public transport while simultaneously altering the nature of demand. A shrinking overall population inherently means a smaller pool of potential bus riders. While an aging population might suggest a growing segment of residents who will increasingly rely on public transport due to reduced driving ability or cessation of driving privileges , the overall population shrinkage appears to be outpacing this potential increase in demand. This creates a significant "mobility gap"  where the need for transport for the elderly is acute, but the economic viability of traditional, fixed-route bus services to serve this dispersed and often off-peak demand is diminished. This demographic squeeze on demand directly contributes to the unprofitability of bus lines  and the operational challenge of running buses that "often run without passengers". The core issue is that while a segment of the population becomes more dependent on public transport, the overall reduction in total population size means the absolute number of potential riders is decreasing.

Urban Sprawl and Decentralization

The municipal mergers in 2005 significantly expanded Niigata's geographic footprint to over 726 square kilometers. This increased sprawl has introduced new public transportation challenges, particularly concerning the adequate coverage and frequency of bus routes across the enlarged area. Analysis of intra-prefecture migration patterns reveals a strengthening tendency for excessive in-migration to central cities within the prefecture, such as Niigata City and Nagaoka City. Conversely, other surrounding areas within the prefecture are experiencing increasing excessive out-migration. This indicates a concentration of population in certain urban cores, while the population density in the surrounding areas becomes increasingly sparse.   

Urban sprawl and the decentralization of population within the broader Niigata area directly challenge the efficiency and economic viability of traditional fixed-route bus services, exacerbating the impact of overall population decline. The expanded geographic area means bus routes must cover larger distances, leading to longer journey times and higher operational costs per passenger. The decentralization of residents into less dense areas results in fewer passengers per stop and per route, making it difficult to justify frequent service. This spatial redistribution of a declining population renders fixed-schedule, fixed-route bus services inherently inefficient. Buses are often compelled to operate with low occupancy or even without passengers , which severely impacts profitability. This financial strain, in turn, frequently leads to the discontinuation of routes  and reduced service coverage. Such reductions further deter potential riders in these increasingly underserved areas, compelling them to rely more heavily on private cars. This dynamic establishes a negative feedback loop where urban form and demographic shifts continually undermine the viability of bus services.   

The Pervasive Influence of Private Vehicle Ownership

The entrenched culture of private car ownership in Niigata stands as a formidable barrier to increasing bus ridership, further compounded by shifts in commuting patterns due to remote work.

High Car Dependency

Private cars consistently remain the most widely utilized mode of transportation in Niigata. Data from 2013 indicated an exceptionally high car ownership rate of approximately 1.03 cars per person in Niigata City and its vicinities. This figure is particularly notable as the number of vehicles has been observed to gradually increase even as the overall population declines. This high level of car ownership contributes significantly to traffic congestion, especially during peak hours, exemplified by bottlenecks such as the one at Ariake Bridge.   

This situation in Niigata contrasts sharply with broader national trends in Japan, where overall car ownership has been falling. This national decline is partly attributed to an aging and falling population, but also to specific policy disincentives for car ownership in major metropolitan areas like Tokyo. These disincentives include stringent biennial vehicle inspections that can be costly (e.g., 100,000 yen for a well-maintained car), escalating fees for older vehicles, annual automobile taxes, a 5% purchase tax, high gasoline taxes, and a mandatory "garage certificate" to prove parking availability before a car can be purchased.   

Niigata's increasing car ownership per capita, despite its overall population decline, highlights a significant divergence from national trends in major metropolitan areas and a lack of effective policy disincentives for private car use. This makes it extremely challenging for public transport to compete. A high and increasing rate of private car ownership directly translates to a strong preference for personal vehicles, thereby reducing the demand for public transport services. The convenience of door-to-door travel offered by cars is perceived to outweigh the benefits of buses, especially in a sprawling urban environment where public transport may not offer the same flexibility or reach. This deepening reliance on private cars means that even as the population shrinks, the remaining residents are becoming more car-dependent. This intensifies the competition faced by public transport and undermines efforts to shift modal choice, as the "mobility in Japan has improved overall"  largely due to private car use rather than public transport. The absence of stringent disincentives for car ownership and use in Niigata, unlike in Tokyo , means that public transport operates on an uneven playing field. Without policy measures that make car ownership more costly or inconvenient, it is difficult for buses to offer a sufficiently compelling alternative, perpetuating the cycle of low ridership and financial struggles.

Impact of Remote Work on Commuting Patterns

The adoption of remote work has surged across Japan, particularly since the COVID-19 pandemic. By November 2023, over 66% of Japanese companies had implemented remote work arrangements, with the proportion of workers regularly engaging in remote work rising significantly from 20.2% in 2019 to 30.7% in 2023. This trend is projected to continue its upward trajectory. Remote work directly reduces commuting time for employees and contributes to decreased traffic-related environmental impacts by lessening the need for daily travel. Nationally, the demand for work and school commuting, which historically constitutes a substantial portion of transit bus ridership, experienced a considerable decline during the pandemic and is now considered "unlikely to return to pre-pandemic levels".   

The widespread and sustained adoption of remote work represents a fundamental, likely permanent, reduction in peak-hour commuting demand, which traditionally forms the backbone of fixed-route bus services. This necessitates a re-evaluation of service models. The rapid and sustained increase in remote work adoption across Japan  leads to a direct and significant reduction in daily commuting. This is not merely a cyclical fluctuation but a structural change in work patterns  that permanently erodes a major component of the traditional ridership base for fixed-route bus lines. This makes their operation even less financially viable and contributes to the observation of buses "often run without passengers". For Niigata's bus operators, this shift means that even if other factors (such as population decline) were to stabilize, the demand for work-related bus travel would remain depressed. This forces a fundamental re-evaluation of bus service models, moving away from a primary focus on peak-hour commuter services towards more flexible, diversified, or demand-responsive offerings to capture remaining or new types of travel demand, such as off-peak, leisure, or essential services for the elderly. This adaptation adds significant pressure on an already unprofitable industry.   

Operational and Service Quality Deficiencies in Niigata's Bus System

Beyond demographic and competitive pressures, the operational characteristics and perceived quality of Niigata's bus services themselves contribute significantly to lower ridership.

Inefficient Fixed Routes and Schedules

Niigata Kotsu, the primary bus operator, has openly acknowledged that operating buses with fixed schedules and routes is inefficient, particularly in areas experiencing decreasing passenger numbers and depopulation, such as Shimo-machi in Chuo-ku. This often results in buses running with very few or no passengers. The fixed nature of these routes also raises questions about whether passengers can reach their desired destinations at their preferred times.   

Reports from travelers, specifically concerning the Bandai-bashi Line (B1), a major route, highlight significant operational issues. Off-peak travel times are described as excessive, with buses reportedly traveling very slowly (between 20-40 km/h) and frequently waiting at numerous bus stops to avoid departing before their scheduled times. This indicates a clear mismatch between the rigid fixed schedules and actual demand or prevailing traffic conditions.   

The inherent inefficiency of fixed routes and schedules in a low-demand, sprawling, and aging urban environment leads to poor service quality, which directly deters ridership and exacerbates financial losses, creating a self-reinforcing cycle of decline. Low occupancy makes operations financially unsustainable. Slow, unpredictable travel times and unnecessary waiting actively discourage potential riders, making buses an unattractive option compared to the perceived speed and flexibility of private cars. This operational inefficiency directly contributes to the "poor convenience" and "declining revenue"  for bus operators. As profitability suffers , operators are compelled to implement cost-cutting measures, including route discontinuation and reduced frequency. This "downscaling of transport networks"  further reduces the utility and attractiveness of buses, driving more people to private cars and perpetuating the ridership decline. The specific issue of buses "waiting at stops"  is particularly detrimental to perceived efficiency and reliability, actively discouraging riders who prioritize their time.

Inconvenient Infrastructure and Information Gaps

The public transportation system in Niigata faces challenges related to infrastructure and information accessibility. Transfers between bus lines and to other modes of transport, particularly rail, are often inconvenient. Furthermore, comprehensive and easily obtainable information regarding bus arrivals and connection times is frequently lacking. Bus stops and taxi stands are sometimes situated in inconvenient locations, and finding adequate parking near public transportation hubs is not always easy. While "Niigata Bus i" does provide real-time information, its scope is limited to highway express buses, rather than the broader local network. This indicates a significant gap in comprehensive real-time information for daily commuters navigating the city's various bus lines.   

A lack of seamless integration between transport modes, poor information accessibility, and inconvenient physical infrastructure create significant friction points for potential riders, undermining the overall attractiveness and utility of the bus system. These issues increase the perceived effort and complexity of using public transport, making it less competitive with the simplicity and door-to-door convenience offered by private cars. For an aging population  who may have reduced physical mobility, cognitive challenges, or be less familiar with digital tools, these barriers are amplified. This directly contributes to the "poor access" symptom identified in regional transport challenges  and limits their ability to rely on public transport even when they lose driving privileges. The absence of comprehensive, easily accessible real-time information across the entire network prevents potential riders from making informed travel decisions, further reducing confidence in the system. 

Financial Viability and Route Discontinuation

Public bus services in Niigata are provided by multiple private operators. Due to declining ridership, these services have suffered from decreasing profitability, a situation that has directly led to the discontinuation of many routes. This issue is not unique to Niigata; nationally, the bus business in Japan has been unprofitable for an extended period. Approximately 85% of rural bus operators across Japan operate below their financial break-even point.   

While the balance ratio (current income divided by current expenditure) for the bus industry has shown some improvement nationally , this trend may be a consequence of aggressive cost-cutting measures, including service reductions and route rationalization, rather than an increase in revenue generated from higher ridership. In areas where private bus operators have withdrawn services, community bus routes have increasingly been introduced. These community services often require substantial subsidies from municipalities to remain operational. For example, one municipality reported subsidies for its local bus service amounting to more than 3,000 yen per ride.

The chronic unprofitability of bus services, exacerbated by declining ridership, forces operators to cut routes and frequencies, which then further depresses demand. This creates a growing fiscal strain on municipal governments, highlighting the unsustainability of the current operational model without significant public subsidy or radical restructuring. Reduced profitability compels bus operators to reduce service levels, leading to a "downscaling of transport networks". This includes fewer routes and lower frequencies, directly impacting the availability and convenience of bus travel. This contraction of services further diminishes the utility and attractiveness of buses for remaining residents, pushing them towards private cars or other alternatives, thereby accelerating the ridership decline. The increasing dependence on government subsidies  creates a significant and unsustainable financial burden on local governments, diverting funds that could be used for other urban development or public services. The observation that the "balance ratio improving"  for the bus industry, when juxtaposed with declining ridership and route cuts, suggests that financial "improvement" is achieved through service contraction rather than increased demand. This indicates a fundamental unsustainability of the traditional fixed-route bus model in depopulating, sprawling regional areas, requiring a re-evaluation of how essential public transport services are funded and delivered.

Competitive Landscape of Niigata's Transportation Network

The operational environment for Niigata's bus lines is shaped by a broader competitive landscape, encompassing other established transport modes and emerging mobility solutions.

Role of Rail and Shinkansen

Niigata benefits from an extensive rail network, including both local and Shinkansen lines that operate through Niigata Station. The Joetsu Shinkansen, which commenced operations in 1982, significantly diverted intercity passenger traffic that was previously carried by non-Shinkansen lines. While railway use has seen a gradual increase in Japan's three major metropolitan areas , and Niigata has been a pioneer in transforming secondary rail lines into successful tourist-focused "touring trains" , this success does not directly translate into increased local bus ridership. In fact, the overall railway network in Japan is generally shrinking, with major train companies prioritizing investment in high-speed networks that connect metropolises over smaller, peripheral lines with fewer passengers.   

The success and strategic investment in rail, particularly high-speed Shinkansen and niche tourist trains, may inadvertently divert focus and resources from local bus network improvements, while also directly competing for certain types of passenger movements, thus contributing to bus ridership decline. The Shinkansen directly reduces demand for long-distance bus travel. The success of niche rail tourism may draw investment and strategic attention away from the struggling local bus sector, as resources are finite. While rail serves different travel needs (intercity, niche tourism) than local buses, its relative success and perceived viability compared to the bus industry's chronic struggles  highlight a disparity in investment attractiveness and strategic priority. This means that even within the public transport sector, buses face a challenging competitive environment for funding and policy focus, potentially being viewed as a less attractive investment compared to more successful rail projects. This further isolates the bus system in its struggle for ridership.   

Emergence of Alternative Mobility Solutions

The transportation ecosystem in Niigata is also evolving with the emergence of new mobility solutions that present both opportunities and competitive pressures for traditional bus services.

Bicycle Sharing Systems (BSS): Niigata City launched its "Niigata 2km Share-Cycle" BSS in 2022. By October 2022, the system comprised 150 bicycles across 29 stations, recording nearly 200,000 trips with an average trip length of 2km. These systems are expanding globally as sustainable urban mobility solutions, particularly effective in providing affordable "last-mile" connectivity.   

Ride-sharing Services: Local governments in regional Japan, including cities within Niigata Prefecture such as Nagaoka, Minamiuonuma, and Myoko, have begun establishing ridesharing programs, often in the form of shared taxi services. These initiatives are designed to fill transportation gaps that have arisen due to discontinued bus routes. While Japan has historically maintained strict regulations on ride-sharing, new legislation introduced in April 2024 now permits "Private Vehicle Utilization Business" under the supervision of taxi operators. Although ride-sharing services are thriving in metropolitan areas like Tokyo, their expansion into rural regions is still developing. Initiatives such as Nokkaru are specifically targeting mobility needs for the elderly in depopulated areas, offering a service that allows local residents with private cars to provide rides to others in their community.   

The rise of new mobility solutions like bicycle sharing and ride-sharing, while addressing specific "mobility gaps" and "last-mile" challenges, also fragments the public transport market. This potentially draws away ridership from traditional bus lines and necessitates a redefinition of the bus system's role within a broader, more integrated mobility ecosystem. These alternative modes offer new options for short-distance commuting, last-mile connectivity, or on-demand travel, directly competing with or replacing some bus trips, especially those that are less efficient or frequent. The development of these services is often a direct response to the failures or limitations of traditional fixed-route bus services (e.g., discontinued routes, limited frequency, poor access) in regional and rural areas. This indicates a shift in the public transport ecosystem towards more flexible, user-oriented solutions. For conventional bus lines, this means their market share is being eroded from multiple directions: long-distance by rail, short-distance/last-mile by bikes and ride-sharing, and overall by the pervasive private car. This fragmentation requires bus operators to strategically redefine their core value proposition (e.g., high-capacity corridor services, feeder routes to rail, or specialized services) and actively integrate with these new mobility solutions (often referred to as Mobility as a Service or MaaS ) rather than viewing them solely as competitors, to ensure a cohesive and effective overall transport network.   

Conclusion: Interconnected Factors Driving Ridership Decline

The lower bus ridership in Niigata is not attributable to a singular cause but rather stems from a complex and interconnected web of factors. These include the persistent demographic decline and rapid aging of the population, leading to a shrinking and changing ridership base. This demographic shift is compounded by a deeply ingrained and increasing dependency on private cars, which continues to be the preferred mode of transport despite urban sprawl and congestion. Operational inefficiencies within the existing bus system, characterized by rigid fixed routes and schedules that result in empty buses, slow travel times, and inconvenient transfers, actively deter potential riders. Furthermore, the broader competitive landscape, including the strategic focus on rail infrastructure and the emergence of alternative mobility solutions like bicycle sharing and ride-sharing, fragments the public transport market.

These factors often interact in a self-reinforcing manner, creating a challenging cycle of decline. For instance, depopulation directly reduces ridership, which then impacts the financial viability of bus lines, leading to service cuts and route discontinuations. These service reductions, in turn, further drive residents towards private car ownership or alternative modes, perpetuating the decline in bus patronage. This multifaceted problem underscores the need for a holistic and adaptive approach to revitalizing public transport in Niigata.

Strategic Considerations for Revitalizing Bus Ridership

To address the multifaceted challenges contributing to lower bus ridership in Niigata, a strategic shift is required that moves beyond simply attempting to restore past models. The focus must be on adapting bus services to the evolving urban and demographic landscape. Key considerations include:

Service Adaptation and Flexibility: Transitioning towards more flexible and demand-responsive transport (DRT) models is crucial, particularly in sprawling or depopulating areas. This could involve dynamic routing and scheduling based on real-time user requests, as explored in SAVS trials , allowing services to align more closely with actual mobility demand rather than fixed, inefficient routes.   

Integrated Urban Planning and Development: Coordinating land use and transport policies is essential. Implementing Transit-Oriented Development (TOD) and urban consolidation strategies  can help create denser, more transit-friendly environments that naturally support public transport use. This involves strategic planning to reduce the inherent need for extensive private car use by bringing residences, workplaces, and amenities closer to transit hubs.   

Enhancing User Experience and Information: A significant improvement in real-time information accessibility for all bus lines is necessary, moving beyond limited highway express bus information. Streamlining transfer convenience between different transport modes (bus-to-rail, bus-to-bicycle sharing) and optimizing the location and accessibility of bus stops are vital. Addressing specific user complaints about excessive off-peak travel times, slow speeds, and unnecessary waiting at stops  is paramount for improving perceived service quality and attracting riders.   

Sustainable Financial Models: Given the chronic unprofitability of bus services , exploring diversified funding models beyond sole reliance on farebox recovery is imperative. This includes increased and targeted subsidies where necessary to maintain essential services, particularly for vulnerable populations , and fostering innovative public-private partnerships.   

Leveraging Technology and New Mobility: Actively integrating new mobility solutions like bicycle sharing systems  and ride-sharing/shared taxis  as complementary "first/last mile" solutions is critical. These should be viewed as part of a cohesive mobility ecosystem rather than solely as competitors. Furthermore, exploring and implementing automated driving technologies  for future efficiency and service expansion, particularly in areas facing driver shortages , could offer long-term benefits.   

Addressing Workforce Challenges: Given the national challenge of an aging workforce and driver shortages in public transport , implementing comprehensive strategies to attract, train, and retain bus drivers is a fundamental requirement for maintaining and expanding services.   

By adopting these strategic considerations, Niigata can work towards creating a more resilient, user-centric, and financially sustainable public transport system that better serves the evolving needs of its population and urban landscape.
