New Transit Yurikamome (新交通ゆりかもめ, Shinkōtsū Yurikamome), formerly the Tokyo Waterfront New Transit Waterfront Line (東京臨海新交通臨海線, Tōkyō Rinkai Shinkōtsū Rinkai-sen), is an automated guideway transit service in Tokyo, Japan. It connects Shimbashi to Toyosu, via the artificial island of Odaiba, a market in which it competes with the Rinkai Line. It is operated by Yurikamome, Inc., a third-sector subsidiary of Tokyo Rinkai Holdings, Inc., itself funded by the Tokyo Metropolitan Government.

The line is named after the black-headed gull (yurikamome in Japanese),[3] a common denizen of Tokyo Bay and the official metropolitan bird.[4]

History

[edit]

The line was one of the two lines constructed to transport people into the Rinkai subcenter, the other line being the Rinkai Line. The Rinkai subcenter was planned to be the seventh subcenter of Tokyo as far as back in 1979. In April 1989, the subcenter was planned to have 60,000 residents and 110,000 workers by the start of the 21st century. This plan was forced to be revised upon the collapse of the asset price bubble. The opening of the Yurikamome and the Rinkai line in 1995 and 1996 was planned to be ready by the start of the World City Expo [ja] in 1996. However, the expo was cancelled by Yukio Aoshima in April 1995.[5] On 1 November 1995, the section between Shimbashi and Ariake opened, using a temporary Shimbashi station. In the first few months of operation, ridership hovered around 27,000 passengers per day.[6]

In 1996, the Tokyo Metropolitan Government re-zoned Odaiba from pure business and residential to also permit entertainment zones. The island provided Tokyo with a strip of livable seaside, and within one year, ridership doubled to 60,000. As more and more restaurants, shopping malls, exhibition centers and museums opened, traffic continued to grow.[6] On 22 March 2001, the current Shimbashi station opened and the temporary station closed. Shiodome Station opened on 2 November 2002. [7] On 27 March 2006, the section between Ariake and Toyosu opened and stations adopted letter and number codes based on Tokyo Metro.[8]

On 16 March 2019, two stations were renamed: Fune-no-kagakukan became Tokyo International Cruise Terminal, and Kokusai-tenjijō-seimon became Tokyo Big Sight.[9]

There was an unrealized plan to extend the line to Kachidoki Station from at least 2000, although this plan was not in the 2016 list of considered transit routes.[10][11]

Infrastructure

[edit]

The Yurikamome is Tokyo's first fully automated and driverless transit system, controlled entirely by computers with no drivers on board. However, the line is not the first fully driverless transit line in Japan, as the Nagoya Municipal Subway tested the system in 1960, the driverless technology was used during the Expo '70, and Kobe's Port Liner opened in 1981 before the Yurikamome.[12][13] The trains run with rubber-tired wheels on elevated concrete track guided by the side walls.[12]

Rolling stock

[edit]

The line uses Mitsubishi Heavy Industries rubber-tired "Crystal Mover" technology.[14] As of 8 April 2021, the following train types are used on the line, all formed as six-car sets.[15]

Ridership

[edit]
Route of Yurikamome

Ridership on the line peaked at over 200,000 daily boardings in 2000,[19] but declined substantially by 2004 as the Rinkai Line, which opened a year after the Yurikamome Line, expanded into more of the waterfront area and offered lower fares. Between 2004 and 2006, four new stations were added, which raised ridership slightly. As of 2023, daily ridership totals are roughly 97% of pre-pandemic levels with patronage shifting to the eastern end of the line.

It serves as a vital link between Tokyo's urban core and its redeveloped waterfront districts, including the artificial island of , offering passengers panoramic views of and crossing the iconic Rainbow Bridge. Inaugurated on November 1, 1995, the line was originally 12 kilometers long, extending from Shimbashi to Ariake Station to support the development of the waterfront area in preparation for urban expansion and events like the economic initiatives. A 2.7-kilometer extension to opened on March 27, 2006, adding four new stations to enhance connectivity to emerging commercial and residential zones in the Toyosu area. The system is entirely driverless, controlled by a central computer using dual lateral guide rails for precise navigation, and features six-car trains with capacities of 306 to 338 passengers each, operating at speeds up to 60 km/h. Services run daily from 5:00 a.m. to midnight, with headways of approximately 5 minutes on weekdays and 4 minutes on weekends and holidays, ensuring efficient transport for commuters, tourists, and event attendees. Yurikamome's significance lies in its role as Tokyo's pioneering automated urban transit line, promoting with fully wheelchair-friendly stations equipped with elevators and barrier-free facilities, and integrating seamlessly with other rail networks like the JR Yamanote and lines at key interchanges. As of recent years, it accommodates an average of approximately 133,000 daily passengers, underscoring its importance in alleviating road congestion and supporting in the Odaiba-Toyosu corridor, home to convention centers, shopping malls, and leisure attractions. The line's innovative design and reliable operation continue to exemplify advancements in sustainable urban mobility in one of the world's densest metropolitan areas.

Overview

Route and extent

The Yurikamome line spans a total length of 14.7 kilometers, operating as an entirely elevated double-track guideway that connects in Minato Ward with in Koto Ward. The route begins in central at Shimbashi, proceeds through the Shiodome business district, and then heads southward along the waterfront, crossing the iconic Rainbow Bridge on its upper deck to reach the artificial island of . From there, it serves key waterfront developments in the Odaiba, Aomi, Ariake, and Toyosu areas, providing access to commercial, exhibition, and residential zones along before terminating at Toyosu. The line features 16 stations strategically placed to facilitate urban connectivity and tourism: Shimbashi, Shiodome, Takeshiba, Hinode, Shibaura-futo, Odaiba-Kaihinkoen, Daiba, Tokyo International Cruise Terminal, Telecom Center, Aomi, , Ariake, Ariake Tennis no Mori, Shijo-mae, Shin-Toyosu, and . Key interchanges include direct connections at Shimbashi to the JR , Keihin-Tohoku Line, and Ginza and Lines, enabling seamless transfers from central rail networks. At Shiodome, passengers can access the Toei Oedo Line, while provides links to the Yurakucho and Hibiya Lines, enhancing integration with the broader subway system. Running predominantly at elevations of 10 to 15 meters above street level, the guideway offers passengers panoramic scenic views of , the city skyline, and landmarks such as the Rainbow Bridge, where heights reach 45 to 60 meters above sea level. This elevated design not only minimizes ground-level interference in the dense urban and reclaimed land environment but also emphasizes the line's role in showcasing the waterfront's architectural and natural features.

Key characteristics

The Yurikamome is a fully (AGT) system that operates without onboard drivers or crew, with all functions—including acceleration, braking, door operations, and routing—controlled by centralized computer systems for enhanced safety and efficiency. This driverless design eliminates human error and enables precise, uninterrupted service across its elevated route. The system features rubber-tired running on a dedicated guideway, which contributes to significantly quieter operation compared to traditional steel-wheeled rail systems and provides stable, precise guidance via lateral rails embedded in side walls. Developed by , the technology underpinning Yurikamome supports high-frequency operations, with running at intervals of approximately 4 to 5 minutes to accommodate urban demand. Each six-car set offers a capacity of up to 352 passengers (170 seated and 182 standing), facilitating efficient transport over the 14.7 km route, with an end-to-end journey from Shimbashi to taking about 30 minutes. Tailored for Tokyo's waterfront environment on reclaimed land in , Yurikamome's infrastructure includes an elevated guideway rising 10 to 15 meters above sea level, incorporating additional anti-seismic reinforcements beyond initial designs based on the to withstand seismic activity common in the region.

History

Planning and development

The planning and development of the Yurikamome line emerged in the as part of the Tokyo Metropolitan Government's broader initiative to redevelop the city's waterfront areas, transforming reclaimed land in into a vibrant urban subcenter. This effort positioned the waterfront as Tokyo's seventh designated subcenter, following established hubs like , to accommodate surging demand for office space and foster economic growth amid Japan's booming economy. In 1988, the Tokyo Metropolitan Government established Tokyo Waterfront New Transit Inc. (now Yurikamome Inc.) as a third-sector entity, blending public and private investments to oversee the project's planning, construction, and operations. This structure involved funding from the government to leverage expertise in urban transit while distributing financial risks. The initiative aligned closely with preparations for the proposed 1996 World City Expo in the Odaiba area, intended to showcase Tokyo's urban innovations on the reclaimed land; however, the expo was canceled in 1995 amid fiscal concerns and political shifts under Governor Yukio Aoshima. Despite this, the project proceeded with a core focus on enhancing connectivity between central Tokyo and the emerging Odaiba district, promoting residential, commercial, and recreational development. The initial scope outlined a 12 km (AGT) line running from Shimbashi to Ariake, with a total budget of approximately 170 billion yen, of which 115 billion yen covered and the remainder vehicles and systems. Emphasis was placed on full to eliminate onboard staff, thereby reducing long-term labor costs and enabling efficient, 24-hour operations in a high-density urban corridor. The line's name, "Yurikamome," was selected to evoke the (Larus ridibundus), 's officially designated bird, which is commonly observed along the bay's waterfront, symbolizing the area's natural birdlife and offering passengers scenic views of the urban seascape.

Construction and initial operations

Construction of the Yurikamome (AGT) system commenced in March 1989, following the establishment of the operating company, Rinkai New Transit Co., Ltd., in April 1988. The project involved building an extensive network of elevated viaducts across to connect central with the developing waterfront subcenter, including integration of the guideway into the lower deck of the Rainbow Bridge, a that had opened in 1993. This engineering feat allowed the line to span reclaimed land and water areas efficiently, with completion achieved in 1995 after approximately six years of work. The line officially opened to the public on November 1, 1995, providing service from Shimbashi Station in central Tokyo to Ariake Station, covering 12 kilometers with 11 stations. Initial operations utilized 13 trains, achieving headways of 6 minutes during peak hours and 10 minutes during off-peak periods to accommodate expected commuter and visitor traffic to the new Rinkai waterfront area. As Tokyo's inaugural fully driverless AGT system, the Yurikamome featured rubber-tired trains operated remotely from a central control room located at the Ariake depot, marking a significant advancement in urban automated transit technology. In its early months, the system averaged approximately 27,000 daily passengers from November 1995 to March 1996, falling slightly short of the initial projection of 29,000 riders per day amid the gradual development of the surrounding district. By 1996, ridership began to stabilize as infrastructure in the waterfront area matured. The line, initially known as the Tokyo Waterfront New Transit Waterfront Line under the nickname Yurikamome, was officially redesignated as New Transit Yurikamome in 1998; the operating company followed suit by shortening its name to Yurikamome Inc. in April 2000.

Operations

Service patterns and automation

The Yurikamome line operates daily from approximately 5:00 a.m. to midnight, with the first trains departing major stations around 5:00 a.m. and the last services concluding by 24:00. On weekdays, trains run approximately every 5 minutes, with shorter headways of 3 to 4 minutes during peak hours. Weekend and holiday frequencies are approximately every 4 minutes throughout the day, achieving up to 20 trains per hour per direction during weekday peaks to accommodate commuter and tourist demand. Trains consist of 6-car formations designed for medium-capacity service, each carrying up to 352 passengers. The system relies on (ATC) for precise speed regulation and collision avoidance, supplemented by automatic train supervision (ATS) to oversee overall operations and ensure adherence to schedules. These technologies enable the rubber-tired trains to navigate the elevated guideway efficiently, including steep gradients and curves over . As a Grade of Automation 4 (GoA4) system, Yurikamome runs with fully unattended operation, where all driving functions—from acceleration to door operations—are handled without onboard . Remote monitoring occurs from the Central in Ariake, which coordinates train movements, platform door controls, and real-time adjustments to maintain safety and punctuality. In emergencies, such as power failures or detection of obstacles, automated safeguards halt trains immediately, followed by established protocols for passenger evacuation coordinated by control center staff and station personnel. Maintenance activities, including inspections and servicing of trains and systems, are conducted overnight at the Ariake depot to minimize daytime disruptions. No crew operates on the trains themselves, but dedicated staff are present at key stations—Shimbashi, Ariake, and —to assist passengers, manage ticketing, and handle incidents. For , every station features elevators connecting all levels, enabling seamless travel for users and those with mobility aids. , integrated since the line's opening, enhance by preventing falls and aligning with the automated door sequences on trains.

Fares and integration

The Yurikamome operates a distance-based system, with adult one-way tickets priced at ¥190 for short trips (1-3 stations), ¥260 for medium distances, ¥330 for longer segments, and ¥390 for the full line from Shimbashi to ; child fares (ages 6-11) are half the adult rate at ¥100, ¥130, ¥170, and ¥200, respectively, while children under 6 travel free when accompanied by an adult or paying child (up to two per ticket holder). IC cards such as and are fully compatible, allowing contactless entry and exit at automatic gates with fares slightly discounted (e.g., adult ¥189-¥388), enabling seamless transfers to other transit lines without additional ticketing. Paper tickets are available via multilingual vending machines at all 16 stations, and round-trip options cost twice the one-way with two-day validity. For group travel, a flat ¥10 discount applies per regular ticket for standard groups of 25 or more (including leader) and student groups of 26 or more. Tourist options include the Yurikamome Enjoy Pass, a one-day unlimited ride ticket priced at ¥820 for adults and ¥410 for children, purchasable digitally via smartphone app or at stations for QR code scanning at gates. In November 2025, for the line's 30th anniversary, a special QR one-day pass is available at ¥30 for adults and children, on sale from November 15 to 21 for use on any one day between November 22 and December 1. Post-2020 enhancements have emphasized contactless options, including credit/debit card tap-to-ride introduced on July 14, 2025, at all stations (with a daily cap of ¥820) and expanded digital passes for reduced physical contact during peak periods. Integration with Tokyo's broader transit network facilitates easy access to key areas, with direct transfers at to JR lines (including Yamanote and Keihin-Tohoku) and subways ( and Lines) via connected walkways and shared IC card usage. At Hamamatsucho Station, passengers can transfer to JR lines and the for access, while Station provides immediate connections to the Yurakucho Line, all without exiting fare-paid zones when using IC cards. The line participates in bundled ticketing with the 24-Hour Ticket (covering and Toei lines), available as combo passes for unlimited travel starting from ¥1,500, enhancing convenience for visitors exploring central Tokyo and waterfront districts. Promotional discounts target event-goers, such as reduced fares or bundled passes for exhibitions at (accessible via nearby Kokusai-Tenjijo Station), including special offers during major shows like the Tokyo Toy Show and Japan Mobility Show to boost ridership during high-demand periods. The system is operated by Yurikamome Inc., a specialized entity focused on the waterfront line, with operational support from the to maintain service on less profitable segments.

Infrastructure

Guideway and technical systems

The Yurikamome line utilizes an elevated double-track guideway measuring 7.5 meters in width, optimized for urban waterfront environments with lateral guidance provided by side walls. Rubber tires on the vehicles handle both and along the track, enabling low , reduced vibration, and flexible routing compared to traditional rail systems. This design allows the guideway to integrate seamlessly with existing infrastructure, such as spanning the lower deck of the Rainbow Bridge without dedicated tracks, leveraging the bridge's double structure that also accommodates roads and promenades. Power is supplied via a 600V three-phase AC system using rigid double trolley wires, which supports efficient distribution across the 14.7 km route. The system incorporates to recapture during deceleration, enhancing overall and reducing power consumption. is prioritized through earthquake-resistant compliant with Japanese standards for elevated structures in seismic zones, including robust foundations and elements to mitigate vibrations. Operations rely on a centralized (ATC) system for fully automated guidance, with onboard and trackside controllers ensuring safe speeds and precise positioning. Transmitters positioned at intervals (240 m, 85 m, and 10 m before stations) provide distance data to facilitate accurate stopping and door alignment. The guideway's geometry supports a maximum gradient of 6% and a minimum radius of 30 m, accommodating tight urban turns while maintaining stability for rubber-tired vehicles.

Stations

The Yurikamome line operates 16 elevated stations spanning 14.7 kilometers from Shimbashi in central to in the waterfront district, with an average spacing of approximately 1 kilometer between stops. All stations feature a uniform design, including full-height for passenger safety, escalators and elevators for vertical circulation, and island platforms to accommodate bidirectional service. This consistency enhances operational efficiency and provides panoramic views of and the city skyline from the elevated structures.

Role in Tokyo's transport network

The Yurikamome line plays a crucial role in Tokyo's transport network by providing seamless connectivity between central Tokyo and the rapidly developing waterfront districts of Odaiba and Toyosu. Operating as an automated guideway transit (AGT) system, it links Shimbashi Station in Minato Ward directly to Toyosu Station in Koto Ward, traversing the Rainbow Bridge and serving key stops on the artificial island of Odaiba, which was constructed on reclaimed land in Tokyo Bay. This route facilitates efficient access to mixed-use areas that combine residential, commercial, and recreational spaces, supporting urban expansion in the waterfront subcenter. By offering a reliable alternative to road travel, the line reduces car dependency in the waterfront zone, where initiatives encourage passengers to transfer from parking facilities to public transit, thereby alleviating traffic congestion around Tokyo Bay. Economically, Yurikamome significantly boosts and convention activities in the region, with about 60% of its daily riders comprising attracted to Odaiba's attractions and the nearby , Japan's largest exhibition center that draws roughly 14 million visitors annually across 300 events. The line has also aided post-2020 Tokyo Olympics redevelopment efforts, including the Ariake Urban Sports Park, which repurposes Olympic venues into public facilities to sustain economic vitality in the waterfront. These contributions enhance Odaiba's status as a hub for innovation, leisure, and business, fostering growth in an area originally envisioned as an urban expansion project. In terms of sustainability, the electric-powered, rubber-tired AGT system minimizes emissions and noise compared to traditional rail or , helping to curb vehicle traffic across the bay area. It complements eco-conscious urban projects, such as the 2018 relocation of the to , which introduced a modern, enclosed facility for improved efficiency and hygiene in seafood distribution. Despite competition from the parallel serving similar corridors, Yurikamome maintains viability through government subsidies from the and national sources, which fund infrastructure and operations amid fluctuating off-peak usage. Plans for potential extensions, such as to Kachidoki Station, have been proposed but remain on hold since 2016. Culturally, Yurikamome's fully driverless operation—achieving Level 4 —serves as an iconic showcase of Japan's technological prowess in urban mobility, offering panoramic views of the skyline and bay that captivate international visitors and promote the nation's advancements in automated globally. With average daily ridership around 133,000 as of 2024, it underscores the line's integral position within Tokyo's framework.
