Mar 19–22, 2026 Shizuoka, Yamanashi, and Nagano Sauna Trip

I already knew the saunas of Yamanashi and Nagano were so incredible they could be called a sauna mecca. Thanks to the powerful natural circulation centered on Mount Fuji and the Northern and Southern Alps, exceptional water springs up everywhere. Just thinking about immersing myself in those cold plunge baths makes me tremble with excitement. I also wanted to make my dream of taking a sauna while gazing at Mount Fuji come true. To satisfy that desire, the ultimate trip was about to begin. First, I'll start by bringing you Sauna Shikiji, which boasts Japan's strongest cold plunge bath.
