Overview
Misato Observatory is a public observatory located in rolling hills at approximately 430 meters elevation in Kimino Town, Kaiso District, Wakayama Prefecture. Featuring a 105-centimeter reflector telescope, it carries the catchphrase "a miraculous starry sky spot where you can meet the Milky Way."
