Koga Onsen Yapponpon no Yu is an onsen in Koka, Shiga prefecture, Japan. Its sodium-chloride thermal water, at 40°C, serves an indoor bath, an outdoor rotenburo and a sauna.

Insider tip — Koka (甲賀) is Japan's most famous ninja stronghold — the rival clan to Iga, Mie. The Koka Ninja Village (Koka Ninja no Sato) reconstructs shinobi training grounds just minutes away. Soak here after testing your stealth skills on the obstacle course, then explore the cedar-forested Tanakami Mountains that once hid entire ninja villages from enemy warlords.
