Inunakisan Motoyu Onsen: Yama-no-Yu – Osaka’s First Registered Hot Spring!
A hidden hot spring surrounded by nature, Inunakisan Motoyu Onsen “Yama-no-Yu” offers a rare 100% free-flowing natural spring. In 1959, owner Takahara Takefumi and his father discovered the source, making it Osaka’s first registered hot spring. This led to the creation of Osaka’s only onsen village, as nearby inns also gained access to the waters. Visitors from across Japan come for its therapeutic benefits, with many reporting improvements in atopic dermatitis. With its rich history and high mineral content, this is a truly exceptional onsen experience.
