Hamasaka Onsenkyo is a hot spring area in Shinonsen Town, Mikata District, Hyogo Prefecture. Located in the historic Tajima region, it consists of three hot spring areas: Shichikama Onsen, Futsukaichi Onsen, and Hamasaka Onsen. Surrounded by beautiful natural scenery and blessed with abundant thermal water, the resort is popular with both local residents and visitors seeking relaxation, regional cuisine, and a taste of traditional hot spring culture.
In 1971, Hamasaka Onsenkyo was selected as the first project under a national energy-saving model initiative. The program aimed to make effective use of local natural resources and promote more efficient energy consumption. The hot spring area’s abundant thermal energy made it a notable example of how natural resources could contribute to regional development.
On April 16, 1991, Hamasaka Onsenkyo was designated a National Health Resort Hot Spring Area through Environment Agency Notification No. 22. This designation recognized its value as a place for relaxation and recuperation and helped establish its reputation as a destination for visitors from across Japan.
JR Hamasaka Station on the San-in Main Line is the main railway station serving the area. The hot spring sources are centrally managed, ensuring a plentiful supply of thermal water. In addition to supplying inns and public bathing facilities, the system distributes hot spring water directly to ordinary households.
Hamasaka Onsenkyo is particularly known for the large number of homes receiving hot spring water, a feature that reflects how deeply the springs are woven into everyday life in the community.
Nearby Hamasaka Fishing Port is renowned for its landings of firefly squid, known in Japanese as hotaru-ika. The area is also famous for snow crab, locally called Matsuba-gani. Many inns serve seasonal dishes prepared with fresh seafood from the Sea of Japan, making local cuisine an important part of the hot spring experience.
Depending on the season, visitors can enjoy the delicate flavor of firefly squid or savor the rich sweetness of snow crab. A stay in Hamasaka is an excellent opportunity to combine hot spring bathing with the distinctive seafood culture of northern Hyogo.
