Insider tip — In Himi, the Toyama fishing city blessed with the finest buri yellowtail in Japan (caught in winter under the snowy Tateyama mountain panorama), Soyu at Himi Onsenkyo draws saline coastal spring water with the mineral richness of Toyama Bay's deep cold waters; bathe with the Tateyama Kurobe alpine range glowing white across the bay — one of Japan's most breathtaking spa views from any season.
