The Oshiraji No Taki Waterfall in Tochigi prefecture is a scenic mountainous pool and accompanying waterfall. The pool of water has a stunning cobalt blue color, complementing the deep greens of the foliage and the slate grey facade of the rock faces. With little fanfare around it, and no touristy buildings around, Oshiraji Falls make for a great mountainous retreat. Anyone looking to get away from the hustle and bustle of Japanese city life will be pleasantly surprised at this hidden gem.
