This is a scenic spot from which you can see all of Muroran City. Although not a very high mountain at 199.6 meters above sea level, on a clear day you can see as far as Mt. It is also known as a treasure trove of wild birds.
The TV tower at the top of the mountain can be lit up from sunset to midnight (until 23:00 midnight from October to March) by applying with a message, and has been lighting up the city of Muroran continuously since it started in 1988.
