A 17,820-yen "First Seat," designed for single passengers, offers a box-style arrangement that is not a private compartment but can be converted into a bed by folding down the seat surface. The 20,870-yen "Premium Room" provides a fully private compartment with a sofa facing the window, which transforms into a bed, allowing passengers to relax, sleep comfortably, and enjoy the passing scenery in solitude. These sleeper services can now be found across Japan, with multi-day luxury tours that circle regional areas also proving highly popular. Among the major overnight trains currently operating are Sunrise Seto/Izumo, WEST EXPRESS Ginga, Train Suite Shiki-Shima, Twilight Express Mizukaze, and Seven Stars in Kyushu.
