Akebono Kodomo no Mori Koen is a whimsical Moomin Valley- inspired park nestled in the mountains of Saitama in Japan and is free to enter. It consists of a collection of adorable buildings, bridges, a tree house, and a light-house in the center of a small pond.

The house (pictured above) has grass roof with solar panels. The inside of the building has three floors, with elaborate, wooden staircases and a beautiful iron railing.
