Traveling from Higashihiroshima to Atami requires transferring between two train services. Initially, passengers will board the Sanyo Line Limited Express, specifically the 'Kodama' train, which operates at speeds of up to 120 km/h (75 mph). This leg of the journey takes approximately 2 hours and includes key stops in cities like Hiroshima and Okayama before reaching the next transfer point at Shin-Kobe Station.
Once at Shin-Kobe, travelers will transfer to the Tokaido Shinkansen. The fastest option, the Nozomi train on the Tokaido Shinkansen line, can whisk passengers to Atami in around 1 hour, with speeds reaching up to 300 km/h (186 mph). This route offers fewer stops than other services, making it the quickest choice for reaching Atami from Higashihiroshima.
While the Limited Express offers comfortable seating with standard amenities, the Nozomi Shinkansen provides a more rapid experience. Overall, this route presents an efficient mix of regional and high-speed travel for those looking to experience both the Shinkansen and Japan's scenic landscapes.
