Where can I smoke on the train?

Smoking is prohibited on the Hokuriku Shinkansen.
On the Sanyo Shinkansen, please use the smoking room by the foyer (some trains do not have
smoking rooms).
Smoking is prohibited on all conventional trains, with the exception of some private rooms on the Sunrise Seto and Izumo trains and the smoking room on the TWILIGHT EXPRESS Mizukaze
train.
