The Odawara to Hashima route is primarily serviced by the Shinkansen, specifically the Hikari service. This train operates at speeds reaching up to 285 km/h (177 mph), covering the approximately 220 km distance in around 1 hour and 45 minutes. The Hikari Shinkansen provides a good balance of speed and regional accessibility, making several stops, including at Shin-Yokohama and Nagoya, before reaching Hashima.
There are also other service options, such as the Kodama Shinkansen, which is a slower option that makes more frequent stops along the way, leading to a travel time of about 2 hours and 40 minutes. While the Kodama service is less speedy, it allows travelers to experience intermediate destinations.
Both services offer different seating classes, accommodating varying preferences for comfort. The Hikari is ideal for those looking for a fast trip with fewer stops, whereas the Kodama ensures a broader experience of the local areas along the route.
