Nikko, in the mountainous highlands of northern Tochigi Prefecture, is home to one of Japan's most spectacular UNESCO World Heritage sites — the Toshogu Shrine complex, an extraordinarily ornate Edo-period mausoleum built for Tokugawa Ieyasu whose gilded carvings, lacquered gates, and mountain forest setting create a breathtaking synthesis of Japanese decorative art and sacred mountain landscape. Tsuruga-jo Onsen Tochigi, in the greater Nikko highland area, draws on sodium and bicarbonate thermal waters from the geothermal resources of the Nikko volcanic zone, offering restorative baths in a highland setting whose proximity to the Toshogu UNESCO complex, the Kegon Falls plunging 97 metres into the Daiya River below Lake Chuzenji, and the autumn foliage of the Irohazaka mountain road makes it one of Japan's most scenically extraordinary spa destinations. The Nikko Toshogu Shrine UNESCO complex, Lake Chuzenji and Kegon Falls, and the Oku-Nikko highland plateau with its Ryuzu and Yudaki waterfalls create an unmatched concentration of natural and historical grandeur surrounding this northern Tochigi thermal destination.
