Yamaha Exhibit List | Japan Mobility Show 2025
Japan Mobility Show, Japan Mobility Show, JMS
There is a growing movement to replace the fuel used in motorcycles and cars that support urban mobility with hydrogen. The hydrogen-fueled motorcycle "H2 Buddy Porter Concept," jointly developed by Yamaha Motor Co., Ltd. and Toyota Motor Corporation, made its world debut at the Japan Mobility Show 2025.
Hydrogen internal combustion engines emit almost no CO₂ while driving, and are therefore attracting attention as a technology that combines environmental friendliness with practicality.
About Japan Mobility Show 2025
Japan Mobility Show 2025 is one of Japan's largest mobility exhibitions, held at Tokyo Big Sight. In addition to automobiles and motorcycles, it will feature a wide range of mobility-related technologies, including robotics, AI, electrification, and hydrogen energy.
At the 2025 event"Decarbonization" and "next-generation mobility" are the main themesMany companies have announced new means of transportation and initiatives towards a sustainable society.
H2 Buddy Porter Concept technology
The "H2 Buddy Porter Concept" isA motorcycle equipped with a hydrogen-fueled internal combustion engine.
- The rear box is equipped with four high-pressure hydrogen tanks for motorcycles developed by Toyota (capacity: approximately 23L).
- A single full tank can travel approximately 100km
- Hydrogen and air are mixed and burned, and the main exhaust is water.
- Almost no CO₂ emissions
The high-pressure hydrogen tank is protected by a protective frame, ensuring impact resistance of 43.5G front to back and 63G left to right. The design assumes delivery use in urban areas and everyday transportation.

The difference between hydrogen bikes and EVs
| Item | Hydrogen bike (internal combustion type) | EV (electric) |
|---|---|---|
| Navigation method | Hydrogen combustion | Motor driven by battery power |
| Filling/charging | Refills in about 3 minutes | Charging takes several minutes to several hours |
| emissions | Mainly water | No emissions |
| Task | Station maintenance | Charging infrastructure and battery life |
Hydrogen is suitable for commercial use and long-distance travel because it can be refueled in a short time. On the other hand, EVs are quiet and easy to maintain. Each has its own advantages, so it is important to choose the right vehicle for the purpose.
Hydrogen refueling and infrastructure
Hydrogen fuel can be refueled at a hydrogen station by connecting a special nozzle and following the same procedure as gasoline refueling, which takes about three minutes.
- Number of hydrogen stations in operation in Japan: Approximately 154 (as of 2025)
- Gas stations: Approximately 27,000
At this stage, infrastructure development is an issue, and further expansion is necessary for widespread adoption.
Cost comparison of hydrogen and gasoline
| Item | 水素燃料 | gasoline |
| unit price | Approximately 1,200 yen/kg | Approximately 160-180 yen/L |
| Full-fill cost | Approximately 6,000 to 7,000 yen | Approximately 8,000 to 9,000 yen |
| Emissions during driving | Mainly water, almost zero CO₂ | Exhaust gas containing CO₂ |
Fuel efficiency varies depending on the vehicle and system, but at present it may be equivalent to or slightly worse than gasoline vehicles.

world trends
- Japanese government aims to have 1,000 hydrogen stations by 2030
- In Europe and China, hydrogen fuelling is progressing in large commercial vehicles such as buses and trucks
Hydrogen is being considered for use in a wide range of areas, including power generation, transportation, and driving, and is positioned as a core element of energy policy.
My Feelings, Then and Now
- The "H2 Buddy Porter Concept" is a hydrogen bike demonstration model that combines environmental friendliness and practicality.
- Refueling is quick, and the operation feels similar to that of a gasoline vehicle.
- Infrastructure development and fuel costs are the keys to widespread adoption
- Rather than choosing one or the other, coexistence depending on the application is realistic.
Hydrogen-fueled motorcycles have the potential to bring new options to urban mobility and logistics. However, infrastructure and cost challenges still remain. When the technology matures and society is ready, hydrogen may become the norm for motorcycles on your streets.
Thinking about how transportation will change in the future by looking at familiar means of transportation can also lead us to reexamine our own way of life.
