Busshozan Onsen

Contemporary thermal bathhouse in Takamatsu that reimagines the traditional Japanese onsen experience through clean modern architecture and a relaxed, design-forward atmosphere. The facility features both indoor and outdoor soaking tubs filled with natural alkaline hot spring water that leaves skin feeling silky smooth, plus a sauna and cold plunge for the full bathing circuit. After soaking, the on-site cafe serves excellent kakigori shaved ice in summer and warm drinks year-round, with seating in a light-filled space that feels more like a boutique gallery than a bathhouse lobby. Reached by the charming local Kotoden railway line, the surrounding Busshozan neighborhood retains a quiet residential character that contrasts pleasantly with central Takamatsu.
