Hottarakashi Onsen (ほったらかし温泉) is a public hot spring bath facility in the mountains north of Kofu. It offers spectacular panoramic views of the Kofu Plain and the surrounding mountains, including Mount Fuji when visibility is good. The bath opens one hour before sunrise and stays open until after dark to allow visitors to experience both dawn and dusk whilst bathing in the baths' waters.

The facility offers two separate baths with separate admission fees. The Kocchi no Yu ("Here Bath") usually has shorter hours than the adjacent Acchi no Yu ("Over There Bath") which is positioned further east along the mountainside and thus provides the better sunrise vistas. The water itself has a high alkali content and feels silky on the skin.

Besides the baths, the Hottarakashi Onsen complex has some sheltered seating areas and vending machines
