Obama Onsen is a seaside hot spring town in Unzen, Nagasaki Prefecture, facing the Chijiwa Bay of the Shimabara Peninsula on Kyushu Island. The resort is famous for its exceptionally high-temperature siliceous springs — among Japan's hottest — that flow directly to the shoreline, creating dramatic steaming coastal scenery and unique foot-bath promenades along the sea. Its location near the historic Unzen volcanic highland makes Obama Onsen a fascinating destination where geothermal activity, maritime beauty, and Japanese bathing culture converge.
