This is a place where many tourists gather in spring, summer, and autumn. Not promoted as a tourist spot until recent years, the pond is part of an erosion control system that was built to prevent damage to Biei in case of an eruption by nearby Mount Tokachidake.
The Blue Pond is named after is deep blue color which it owes to natural minerals dissolved in the water.
The pond is located along Prefectural Road number 966, which connects central Biei with Tokachidake Onsen via Shirogane Onsen. A free parking lot is located next to the road from where the pond can be reached in a 5-10 minute walk.
