Day 1: Nasu Area – Hidden Gems and Relaxation
Your journey for this adventure begins in Nasu Onsen, a tranquil retreat 35 minutes from Nasushiobara Station, easily accessible from Tokyo in just over an hour via the JR Tohoku Shinkansen.

First, immerse yourself in Tochigi’s oldest hot spring, Shika no Yu. Shika no Yu is a historic hot spring with over 1,300 years of history. Said to have been discovered by a hunter who found a deer healing its wounds in the spring, it is renowned for its milky-white, mineral-rich waters, which can get as hot as 48 degrees centigrade. The rustic wooden architecture, unchanged since its 1941 renovation, offers visitors a timeless escape, and a chance to experience the healing waters before heading into the sacred mountains. Make sure to follow the protocol of an ancient swimming ritual before entering the baths - this is a purification method and prevents lightheadedness from the hot waters.

Accommodation is offered at refined ryokan Sansuikaku, a ryokan where traditional architecture meets modern comfort. Cuisine in this region is equally remarkable.
