Kuju in Oita Prefecture, Oike Springs is a serene paradise where crystal-clear water gushes from underground, forming pools of striking turquoise blue.

Every step along the forest path feels like a journey into a living painting—peaceful, untouched, and deeply spiritual. It’s one of Japan’s most mesmerizing natural wonders, beloved by photographers, hikers, and nature lovers seeking quiet beauty off the beaten path.
