Hydrogen Mobility in Tokyo
Tokyo puts hydrogen where it displaces diesel first: buses on fixed routes, trucks on logistics corridors, port equipment and, increasingly, vessels on Tokyo Bay.
Fuel cell buses: the SORA story
The world's largest operating FC bus fleet runs in Tokyo.
Toyota SORA
Japan's first type-certified fuel cell bus, launched March 2018 and based on the Mirai's fuel cell system. SORA carries up to 78 passengers, emits only water, and doubles as a mobile power source: up to 9 kW output and 235 kWh — enough to light a school-gym shelter for about five days.
Toei Bus deployment
Toei Bus began Japan's first commercial FC route-bus operation in March 2017 and today operates the largest FC bus fleet of any Japanese bus operator: 80 vehicles as of April 2025, supported by the nation's first in-depot hydrogen station at Ariake.
Fleet & targets
Tokyo counted 135 fuel cell buses at the end of FY2024, including 80 on Toei routes. The Tokyo government targets approximately 300 FC buses by the end of FY2030 and subsidizes their purchase (up to ¥50 million per bus) so they cost the same as diesel buses.
Next-generation SORA
A new-generation SORA, jointly developed by Toyota and Isuzu on a full-flat bus platform, launched in October 2026 with roughly 20% less tank capacity and a cruising range extended to over 300 km.

Beyond buses: trucks, taxis, garbage trucks & forklifts
Tokyo's “Commercial First” strategy targets roughly 10,000 FC commercial vehicles and about 100 commercial-vehicle-compatible stations by the mid-2030s.
FC trucks
The Tokyo government expanded subsidies for fuel-cell trucks in FY2025 and also subsidizes conversion to hydrogen-engine trucks. A station compatible with large FC trucks is being built on TMG-owned land at Shinsuna, Koto Ward.
FC taxis
Tokyo began subsidizing FC taxi introduction and fuel costs in FY2025 (up to ¥3.7 million per vehicle, plus fuel support). The city aims for around 600 hydrogen taxis in the coming years.
FC garbage trucks & forklifts
Tokyo strengthens support for municipalities introducing fuel-cell garbage trucks and promotes FC forklifts and cargo-handling equipment for commercial and port use.
Airport ground support
TMG subsidizes replacement of ground-support equipment with fuel-cell alternatives at Haneda Airport — hydrogen in the air, on the apron.

Hydrogen on the water
Tokyo Bay is becoming a proving ground for hydrogen vessels.
Hydro Bingo
Built in 2021 by Japan H2YDRO (a joint venture of Japan's Tsuneishi Facilities & Craft and Belgium's CMB.TECH), Hydro Bingo is Japan's first commercial hydrogen passenger boat, running around Tokyo Bay on a hydrogen–diesel dual-fuel engine with capacity for 80 passengers and up to ~50% CO₂ reduction.
Tokyo Port FC vessels
Tokyo plans to introduce TMG-owned vessels equipped with hydrogen fuel cells, and to bring the Osaka-Kansai Expo hydrogen fuel-cell passenger ship to Tokyo Port (winter 2026 onward), with a public naming vote held in 2026.
Hydrogen dining cruise (2027)
NYK, Yanmar and ENEOS plan to launch a hydrogen fuel-cell dining cruise ship on Tokyo Bay by 2027, using Yanmar's maritime FC system, Toyota hydrogen storage modules and hydrogen supplied from ENEOS stations mainly in Tokyo.

The Tokyo 2020 Olympic hydrogen legacy
The Games turned Tokyo into a city-scale hydrogen showcase — and the infrastructure built for them is still in daily use.
Green hydrogen at the Village
Hydrogen produced from renewable energy at the Fukushima Hydrogen Energy Research Field (FH2R) was piped to the Olympic Village, powering and heating part of the athletes' facilities — the first large-scale use of CO₂-free hydrogen at a Games.
A hydrogen Games fleet
Toyota supplied about 3,700 mobility units for Tokyo 2020, including roughly 500 FCEVs (Mirai, SORA buses and others) — the largest fuel-cell fleet ever assembled for a Games, with nearly 90% of the official fleet electrified.
Legacy: Harumi pipeline supply
After the Games, the former Olympic Village at Harumi became Japan's first residential district supplied with hydrogen by pipeline — feeding fuel cells in common areas and refueling vehicles. The legacy pipeline network is in practical use today.
Ripple effects
The Games validated buses, stations and logistics at scale, seeding today's 135-bus fleet, 21-station network and the current commercial-vehicle push. Tokyo Big Sight, the Games' exhibition venue, still draws part of its electricity from hydrogen.
