Hosho Onsen

Hosho Onsen in Oita Prefecture flows with sulfate and simple thermal waters in a prefecture that holds the extraordinary distinction of producing more hot spring water volume than any other prefecture in Japan, making Oita the unquestioned capital of the country's geothermal bathing culture and home to some of the most remarkable and diverse thermal spring environments found anywhere in the world. The spring's dual mineral profile combines the distinctive sulfate chemistry traditionally associated with relaxation and recovery with the gentle accessibility of simple-type mineral water, producing a balanced bathing experience suited to both restorative and leisurely immersion. Hosho Onsen contributes to Oita's extraordinary thermal tapestry, a prefecture where the concentrated volcanic geothermal energy of the Beppu-Shimabara graben zone produces springs of such variety and abundance that the entire region has been recognized as a thermal heritage of global significance.
