Lake Kinrinko (or more correctly Lake Kinrin – since ‘ko’ means lake) is a large spring fed pond at the base of Mount Yufu in the quaint onsen village of Yufuin, Oita Prefecture.

The lake is easily accessible on foot from Yufuin Station via the Yunotsubo Kaido street.

On the mountain side of the lake there is a public bathhouse with a mixed bathing pool.
