Mount Inasa (稲佐山 Inasa-yama) is a hill to the west of Nagasaki city. The Nagasaki Ropeway allows visitors to travel to the top from Nagasaki. A short walk from the cable car station are several buildings that house transmitters for TV and radio stations that serve Nagasaki and the surrounding area.
There is an observation platform that is popular with tourists as it provides spectacular views of Nagasaki’s “10 Million Dollar Night View”
