The route from Aioi to Atami is serviced primarily by the Limited Express trains, specifically the "Hamakan" and "Fujikawa" services. The Hamakan Limited Express covers the distance at speeds reaching up to 120 km/h (75 mph), allowing travelers to enjoy the scenic views along the coastline while minimizing travel time. The journey typically takes around 2 hours with several stops including popular locations such as Himeji and Sakuya.
On the other hand, the Fujikawa Limited Express is another option on this route, providing travelers with a slightly longer travel time of about 2 hours and 15 minutes, as it makes more frequent stops to cater to local passengers. Both trains offer comfortable seating and small onboard refreshments, making the trip enjoyable and efficient. The choice between the Hamakan and Fujikawa largely depends on the traveler's preference for speed versus access to more local stations.
