Onuma Lake Golf Club

Onuma Lake Golf Club is a 27-hole woodland course set on the southern slopes of Mount Komagatake in Mori, Hokkaido Prefecture, Japan. The layout winds through deep primeval forest, with scattered ponds of varying sizes and streams that cut across and alongside the fairways throughout. These water features are not merely scenic — they actively narrow the lines of play and demand precise shot-making at every turn. Each of the three nine-hole loops has its own distinct character, keeping the challenge fresh across the full round. The streams in particular define the strategy here. Whether running parallel to a hole or crossing the fairway directly, they compress your options and reward careful course management over raw power.
