It is a historic building. It was the former prefectural office and assembly building of Yamagata Prefecture. It is made of brick with neo-baroque wall construction, and the interior has a spacious space reminiscent of a Western church. After being destroyed in a fire in 1911, it was rebuilt in 1916.

You cannot cycle past this point. There is a toll booth and they will stop you (there are signs that say no bicycles past this point). There are hiking trails, but seems difficult to carry a bike up them.

You cannot continue past this point on the hiking trail. There is a toilet and parking lot here. You also cannot cycle to the caldera. There is a toll booth and they prevent cyclists from continuing. If you don’t have a car and don’t want to hike without your bike to the top, this is the best place for pictures.
