Yes, the Hikari Shinkansen trains on the Tokaido and Sanyo lines (connecting Tokyo, Nagoya, Kyoto, and Osaka) definitely feature Green Cars, which are the Japanese equivalent of First Class. In 2026, on the standard 16-car N700S or N700A train sets used for Hikari service, Cars 8, 9, and 10 are designated as Green Cars. These cars offer a 2-and-2 seating configuration (compared to the 3-and-2 in standard cars), providing more legroom, wider seats with deeper recline, integrated footrests, and personal reading lights. While the faster "Nozomi" trains are more frequent, many travelers with a Japan Rail Pass specifically choose the Hikari because the pass covers the Green Car supplement if you have the "Green" version of the pass. In 2026, Green Car passengers also enjoy a quieter environment and access to the "S Work" business features, making it a favorite for those who need to remain productive while traveling at 300 km/h between Japan's major metropolitan hubs.
