A refined inn on the edge of the lake, Minamikan has a choice of 'modern', 'retro' and 'classic' rooms, all with broad views across the water. The top-end 'modern' has a tatami room with twin beds and private cypress-wood onsen. The cheaper 'classic' has seen the likes of literary great Kawabata Yasunari pass through.
There is also an excellent restaurant. The ryokan entrance is set back from the road.
