Facilities

Free Wi-Fi is available on many Shinkansen trains; availability varies by train and cars with the service are marked. Connections can become unstable or temporarily drop in tunnels and mountainous areas, so download anything essential in advance.

Shinkansen power outlets supply AC 100V, but availability and location vary by train type. Newer trains may have an outlet at every seat; on some older sets they are limited to window or end-row seats. Japan uses Type A plugs. No special procedures are required when using the outlets for mobile chargers. If they are available, feel free to use them.

Restrooms are available in each Shinkansen. The number and locations of restrooms may vary depending on the carriage.

Smoking is prohibited in all Shinkansen cars. The onboard smoking rooms on the Tokaido, Sanyo and Kyushu Shinkansen were abolished on 16 March 2024, so the entire network is now non-smoking, heated tobacco included.

Shinkansen trains are equipped with “multi-purpose rooms”. These rooms are private spaces primarily reserved for individuals with physical disabilities or mobility challenges. However, when not in use by passengers with disabilities, these rooms may also be utilized for purposes such as breastfeeding, changing room, or accommodating passengers with health issues. Most Shinkansen trains have one, but not all — and other train types may not. Multi-purpose rooms are usually locked and cannot be accessed without permission. If you wish to use one, you may request the train conductor to unlock it for you.
