About Inasayama
Mount Inasa (Inasa-yama in Japanese) is a hill to the West of Nagasaki that is 333 metres high.
There is an observation platform that is popular with tourists as it provides spectacular views of Nagasaki's 10 Million Dollar Night View. It's called this because various lights of the city below look like a sea of jewellery. This is also a common place for dating for young local couples.
Rock Festivals are also held on the mountain all year round.
