Nagahama Onsen

Nagahama Onsen provides siliceous mineral bathing in the historic castle city of Nagahama on the northern shore of Lake Biwa, where Toyotomi Hideyoshi—Japan's great 16th-century unifier—built his first castle and where the Nagahama Hikiyama Festival is celebrated each April with costumed child actors performing classical kabuki scenes atop elaborate floats, a tradition dating to 1615 and recognized as an Intangible Cultural Heritage of UNESCO. The warm mineral waters ease the fatigue of visitors who have explored Nagahama's beautifully preserved Kurokabe Square—a network of glass art shops and old merchant buildings—and the lakeside park surrounding Nagahama Castle's reconstructed tower. The convergence of Hideyoshi's legacy, living kabuki festival tradition, and Lake Biwa's northern waterscape makes Nagahama one of Shiga's most historically layered and rewarding onsen destinations.
