Kifu no Sho Ryokan in Kaga, Ishikawa prefecture, draws sulfate-calcium thermal waters in the Kaga Onsen group — four historic onsen towns (Yamashiro, Yamanaka, Katayamazu, Awazu) in the Kaga domain of feudal Ishikawa — where the Kaga clan's patronage of Japanese arts produced the highest standard of traditional craft culture outside Kyoto, including Kenzan-yaki pottery, Kaga Yuzen silk dyeing, Wajima lacquerware, and gold leaf work still centered in Kanazawa's 21st Century Museum of Contemporary Art. The sulfate-calcium waters are recognized for skin, joint, and fatigue therapy in a ryokan whose culinary program draws on Kaga cuisine — the most elaborate regional Japanese cuisine after Kyoto's, featuring snow crab, fugu (puffer fish), bamboo shoots, and the seasonal dishes perfected under Edo-period Kaga domain patronage. The Sea of Japan's winter storms and Noto Peninsula's isolation have preserved in the Kaga-Noto cultural zone the most intact traditional Japanese living culture outside Kyoto.
