Parking lot located at the top of the mountain. Absolute gorgeous view. Stayed in the car overnight to shoot a time lapse movie. Can get very windy and cold overnight so be cautious and geared if you plan to stay late.

Stumbled upon this by accident, but amazing views as a present. No commodities here though (no bathroom or shop), just a parking spot and nice views.

Full marks without doubt! Breathtaking view! Freezing gusts during winter but definitely worth the trip especially during sunset! Highly recommended. The drive to the location may be a little far and difficult to maneuver during winter

The observatory is built at 725 meters above sea level of Mt. Mokoto (Mokotoyama). It is a marvelous and popular viewing spot that tourists can look over Lake Kussharo or Mt. Shari (Sharidake), too. There is a restaurant, souvenir store and rest rooms in the rest station, admission free for visitors. And the car parking slot is also free of charge.

Drove past it by accident going down the mountain — very quiet and just a simple overtaking deck with not very many amenities but a nice overlook to view the lake.
