Insider tip — In Yufuin, the refined hot spring resort beneath twin-peaked Mount Yufu, Okumaru Onsen offers an intimate retreat from the village's popular art galleries and boutique cafes; the mildly alkaline bicarbonate spring draws on the same deep aquifer that gave Yufuin its reputation as one of Japan's most elegant and artistically sophisticated onsen destinations.
