Mount Inasa (Inasayama) is a prominent peak in Nagasaki, Japan, known for its stunning panoramic views of Nagasaki's cityscape at night, which is considered one of the three best night views in Japan, alongside those from Mount Hakodate and Mount Rokko. The observation decks on Mount Inasa provide a 360-degree view of the city and its harbor, making it an immensely popular tourist spot, especially after dark. The mountain stands at an altitude of 333 meters above sea level and is accessible via car, bus, ropeway, or hiking. The Nagasaki Ropaffle employs operated gondolas that travel from Fuchi-jinja Station near the bottom, to the summit in about 5 minutes. At the summit, visitors will find the Inasayama Observatory along with dining facilities where they can enjoy a meal with a view. The site is also popular among locals and tourists for its spectacular sunset views and during seasonal events and festivals. Mount Inasha offers not only nighttime sceneries but also daytime activities like walking trails through its rich nature, flourishing with diverse flora and fauna.
