The Toyohashi to Hashima route is primarily served by the Tōkaidō Shinkansen and the Conventional Line. The Nozomi Shinkansen, operating on this line, can reach speeds up to 300 km/h (186 mph) and typically covers the distance in approximately 30 minutes, with minimal stopping. Alternatively, the Hikari Shinkansen, which also runs on the Tōkaidō line, takes around 40 minutes as it includes more stops at stations such as Nagoya and Toyohashi.
In addition to these high-speed options, there are also local trains available that can take an hour or more depending on the schedule and stops. Travelers can choose between Ordinary and Green class seating, with Green Class offering enhanced comfort and spacious seating arrangements.
For those who prioritize speed, the Nozomi service is the fastest choice, while the Hikari provides a good mix of speed and accessibility to further destinations along the route.
