JR Central and JR West will upgrade the seating and facilities in Green Cars on the Tokaido and Sanyo Shinkansen lines, with the new features to be introduced progressively from December 15, 2027.
Cars 8 and 9 will be fitted with “multi-function armrest seats” featuring drink holders and smartphone holders, while Car 10 will offer “partition seats” designed to provide greater privacy from adjacent passengers. The upgrades will apply to Cars 8 through 10 of N700A and N700S trainsets, excluding N700A trainsets scheduled to be retired within the next few years.
All seats will feature improved cushioning and large tables that can be stowed in the armrests. The footrests will be changed to a flip-up design to increase legroom, while the maximum reclining angle will be changed from 123 degrees to 116 degrees.
A new powder room will be installed in Car 9 of N700S trainsets, equipped with a vanity mirror, a full-length mirror, a counter table, and privacy curtains. In addition, the vibration-control system in Cars 7 through 10 of N700S trainsets will be improved, reducing lateral swaying caused when trains pass each other by approximately 10%.
Improvements to communications services and restrooms will be introduced ahead of the other upgrades, progressively from October 26, 2026. On N700S trainsets, the free “S Wi-Fi for Biz” service will be expanded to Cars 9 and 10, in addition to the existing Cars 7 and 8. Cars 8 through 10 will also be equipped with 5G-compatible transparent glass antennas, as used in Supreme Class, to improve connection stability through increased network capacity and other measures.
In addition, on Car 9 of newly built N700S trainsets, the sanitary disposal boxes in women-only restrooms will be redesigned to make their contents less visible. Shared restrooms will also be fitted with baby chairs, in addition to the existing baby beds.
In conjunction with the service improvements, Green Car fares on the Tokaido and Sanyo Shinkansen lines will be revised for travel from December 15, 2027. Depending on the operating distance, one-way fares will increase by between 800 yen and 4,510 yen.
