Mount Inasa (稲佐山, Inasa-yama) is a hill to the west of Nagasaki which rises to a height of 333 metres (1,093 ft).

A short walk from the top ropeway and slope car stations (adjacent to each other) is Mt.

Inasa Overlook, a multi-level observation deck[1] with "360-degree panoramic view"[2] from the rooftop.

Inasa is known as Nagasaki's "10 Million Dollar Night View" (1000万ドルの夜景, Issenmandoru no yakei).

There are also several buildings that house transmitters for TV and radio stations that serve Nagasaki and the surrounding area.
