Hikari (ひかり?, "Light") is the name of a high-speed train service running on the Tokaido and Sanyo Shinkansen "bullet train" lines in Japan. Slower than the premier Nozomi but faster than the all-stations Kodama, the Hikari is the fastest train service on the Tokaido and Sanyo Shinkansen that is covered in the Japan Rail Pass.
JR West began operating the Hikari Rail Star service from the start of the new timetable on 11 March 2000. This service is limited to the Sanyo Shinkansen, and uses special 8-car 700 series trains with a distinctive livery and a maximum speed of 285 km/h. JR West introduced the service to provide better competition against airlines on the Osaka-Fukuoka route. These services do not have Green car accommodation, but the reserved seating cars feature 2+2 seating and also some 4-seat compartments instead of the standard 3+2 arrangement in non-reserved seating cars. The front row of seats in these cars feature power outlets for laptop users.
