Overview
I could not verify Oyunuma Pond as a named location in the Ghost of Yōtei base game from the available reliable evidence. The name clearly refers to real places in Hokkaido, particularly the geothermal ponds at Noboribetsu Onsen and Niseko, but the sources I could access do not establish that either location appears in the game, whether under the same name or as a renamed fictional counterpart.
