The Mt. Inasa Overlook is an absolutely beautiful place to view the sunset. Sitting at an elevation of 333 meters, it offers what is famously called a "$10 million view" of the city. The scenery was spectacular right at sunset and became even better just after, when the sky started changing into incredible colors behind the radio towers.
A quick heads-up on getting to the top if you are visiting soon: I initially tried to head up on my first night but discovered the main transport options were down. The Nagasaki Ropeway is closed for maintenance from June 8 to July 10, 2026. Additionally, the slope rail car is undergoing repairs that are expected to last until the end of October 2026.
Because of the closures, I took a taxi up from the Hilton. It cost between ¥4,000 and ¥5,000, but let me tell you, it was definitely worth the extra cost and effort. The sweeping views of Nagasaki are incredible and not to be missed!
I finally visited Inasayama Observatory, famous as one of the world’s top three night views—and it truly lives up to the hype. Surrounded by mountains, the glowing cityscape below rivals Hong Kong’s. The observatory itself is beautifully maintained. However, the summit parking is small; on busy weekends, it’s better to use the mid-level lot. The wind is very strong, making time-lapse photography challenging. The deck is open 24 hours, so early morning views are also highly recommended. A wonderful experience overall!
The most fantastic night view that I have ever seen. For the tower lovers, you must take the sunset tower pictures.
About the transportation, it needs to take the bus then transit to shuttle bus. Therefore, this place may not be suitable for the elderly. Also, you may need to care about the time you leave as the shuttle bus is not big that you may need to walk to the bus station as well as the bus stations have many people queueing.
Early May 2026- no need to drive up yourself as need to pay 1000 yen to drive up and parked next to observatory deck. Move down a bit and park free at a big parking lot next to the park and it offers free shuttle bus to the deck. Takes less than 5 minutes to reach the deck.
Staffs guiding the traffics are very helpful
The night view here is absolutely awesome! It’s the perfect spot to grab a snack and just chill out. I’m also sharing some drone footage to give you a glimpse of the stunning aerial perspective. I hiked from Nagasaki station to here because the cable car was not open. If you don’t drive and take transportation, please check the cable car time online in case long walking happens.
