Traveling from Higashihiroshima to Tokyo is best done via the Shinkansen, specifically the Nozomi service, which is the fastest option on this route. The Nozomi Shinkansen reaches speeds of up to 300 km/h (186 mph) and covers the distance in approximately 4 hours, making only a few selected stops, such as at Okayama and Shin-Kobe. An alternative is the Hikari Shinkansen, which travels at a slightly reduced speed of around 285 km/h (177 mph) and takes about 4 hours and 30 minutes for the same journey, stopping at additional stations like Hiroshima and Yokohama.
Both trains offer standard and Green Class seating, catering to passengers looking for comfort. While the Nozomi is well-suited for those prioritizing speed, the Hikari offers a blend of accessibility to more destinations along the route while still maintaining a relatively quick travel time.
