Traveling from Atami to Tokyo is efficiently served by the Tōkaidō Shinkansen, specifically the Kodama and Hikari services. The Kodama Shinkansen stops at all stations along the route, including Odawara and Shin-Yokohama, with a journey time of approximately 1 hour and 40 minutes. It operates at speeds of up to 240 km/h (149 mph). On the other hand, the Hikari service offers a slightly quicker option, as it makes limited stops and can cover the distance in about 1 hour and 20 minutes, reaching the same top speed of 300 km/h (186 mph) between major stations.
Passengers can expect modern amenities onboard, with comfortable seating options in both Ordinary and Green classes. The Hikari service, being quicker and less frequent, is preferred by those prioritizing speed, while the Kodama’s extensive station stops cater to travelers looking to visit smaller towns along the route.
