Green Park Omoide no Mori / Kutsuki Onsen Tenku is located in Takashima, Shiga Prefecture. Its bicarbonate spring, at 40°C, fills an indoor bath and an outdoor rotenburo, with a sauna also on site.
Insider tip — Kutsuki Onsen Tenku, the sky-high spring, sits in the remote Kutsuki Valley of the mountains northwest of Kyoto where the ancient Saba Kaido highway carried salted mackerel from Obama Bay on the Sea of Japan to the imperial kitchens of Kyoto. The Green Park Omoide no Mori preserves forest recreation facilities in a valley whose cedar forests and mountain streams still feel entirely removed from the urban world below.
