Traveler reviews

Mt. Inasa offers the absolute best views of Nagasaki. The night scenery is stunning and definitely lives up to the hype! While the ropeway was a great ride, the slope car looks like a cool, modern alternative that I’d love to try on my next trip. It's a must-visit spot if you want to see the city lights sparkle.

The ropeway is a 30 minutes walk from Nagasaki station. Tickets are easy to purchase at the counter. There's a beautiful shrine next to waiting area. The observatory on top of the hill shows one view towards the city, and opposite side is full of mountains. It's advisable to visit just before the sunset to enjoy the magnificent sceneries of the sunset. One can get a view of the city from the top in daylight and after illumination. There is way to walk down to Inasa-Park which I saw, some visitors opted.

Mt. Inasa Overlook offers one of the most breathtaking panoramic views in Nagasaki. From the summit, visitors can enjoy stunning scenery of the city, harbor, and surrounding mountains, especially during sunset and at night when the city lights create a spectacular view. The observation area is spacious, clean, and well maintained, making it comfortable to relax and take photos. It’s a must-visit spot for anyone looking to experience Nagasaki’s famous night view.

We enjoyed the rope car ride up and down the mountain, which allowed us to capture the views alongside the mountain. The weather was cool and the cafe had lovely cakes.. but the most amazing view was to be had at the top of the observatory. Arriving just before sunset means you get a better collection of the riot of colours as the sun set

You can drive to the mountaintop if you arrive before 6 p.m. (paid parking). Otherwise, you can park halfway up the mountain for free and take the cable car to the top. The observation building offers a 360-degree view. I’d say it’s my pick for the best night view in Japan.
