tickets – On which trains in Japan is reservation mandatory?

First a reminder: whether one posseses a rail pass such as the Japan Rail Pass has no effect on seat reservation requirements. If reservation is required, it remains so if you have a rail pass. Of course, a rail pass usually allows you to make reservations free of charge, but it is still necessary to visit the ticket office to make your reservation. (Note that some minor regional passes do not allow you to make reservations; in that case all-reserved trains require payment of at least the reservation fee.)

Firstly, there are four all-reserved Shinkansen services. Note that all services on the Tokaido-Sanyo-Kyushu Shinkansen between Tokyo and Kagoshima-Chuo, serving Nagoya, Kyoto, Osaka, Hiroshima, Fukuoka, Kumamoto, etc. have non-reserved seats.

  • The Hayate and Hayabusa services on the Tohoku-Hokkaido Shinkansen between Tokyo and Shin-Hakodate-Hokuto. However, if your trip is fully on the section between Morioka and Shin-Hakodate-Hokuto, see the note at the bottom.
  • The Komachi services on the Akita Shinkansen between Tokyo and Akita. However, if your trip is fully on the section between Morioka and Akita, see the note at the bottom.
  • The Kagayaki services on the Hokuriku Shinkansen between Tokyo and Kanazawa.

If you try to make a reservation on one of those trains and the train is fully booked, you will have the option to obtain a standing ticket, which as its name implies lets you ride the train by standing in the intervals between carriages. A standing ticket is slightly cheaper than a reserved seat ticket, as it does not include the seat reservation fee. It is not possible to obtain a standing ticket in any other circumstance, such as if the train is not fully booked (in order to save money) or on any train other than the four above.

The two “premium” express services serving Narita airport are also all-reserved:

  • The JR Narita Express, serving many stations in the greater Tokyo area. However, see the note at the bottom.
  • The Keisei Skyliner, serving Nippori and Ueno.

The two surviving regularly scheduled overnight trains:

  • The Sunrise Seto, between Tokyo and Takamatsu.
  • The Sunrise Izumo, between Tokyo and Izumoshi.

Finally, almost all “touristy” trains are all-reserved, such as:

The easiest way to find out whether a given train has unreserved seats (or, in general, which seating options are available on it) is to look it up on Hyperdia, and see what options are available in the drop-down list of the “Seat Fee” column. If the column is empty, it means the train is an ordinary commuter train, where reservation is not possible in the first place.


Note about the Hayabusa, Hayate and Komachi services beyond Morioka. To compensate for the fact that no services with non-reserved seats exist beyond Morioka, it is possible to board those services without a reservation, by purchasing a “special limited express ticket” (特定特急券) instead of a regular reserved-seat limited express ticket. A special limited express ticket works in essentially the same way as a non-reserved-seat one would: it is cheaper than a reserved-seat one since it does not include a seat reservation fee, and it allows the holder to use any vacant seat, with the caveat that if another passenger has a reserved-seat ticket for that seat, the latter has priority. Rail pass holders, meanwhile, can simply board with just their pass.

Note about the Narita Express. Similarly, the Narita Express can be boarded without a reservation, by purchasing a “non-designated seat ticket” (座席未指定券) instead of a regular reserved-seat limited express ticket (or just boarding with a rail pass). As above, a non-designated seat ticket allows the holder to use any vacant seat, with the caveat that reserved-seat ticket holders have priority. However, a non-designated seat ticket costs the same as a reserved-seat one. A non-designated seat ticket can also be converted to a reserved-seat one at no extra cost.
