Perched atop 333-meter Mt. Inasa in central Nagasaki City, this observatory features a cafe and restaurant. It offers views not only of Nagasaki Bay and the surrounding area, but also of Unzen, Amakusa, and the Goto Islands in the distance.

The scenery is impressive during the day, but the beauty after dark is also well worth seeing. Often called the “$10 million night view,” the panorama was recertified as one of the “World's New Three Great Night Views,” alongside Monaco and Shanghai, at the Night View Summit in Nagasaki in 2021. Together with the lighting display installed in the observatory floor, it creates a romantic atmosphere.

Several hiking trails lead to the summit, making it possible to reach the observatory on foot. For easier access, take the Nagasaki Inasayama Slope Car, which runs from the middle of the mountain to the summit, or the ropeway. Designed by a world-renowned industrial designer, the gondolas feature an innovative shape and glass on all sides, providing unobstructed views during the ride. The scenery offers a different perspective from the observatory itself.

    As the ropeway climbs to the summit, the city of Nagasaki and its harbor gradually come into view. The most anticipated part is the scenery after nightfall, when the city lights stretch along the valleys and bay, sparkling in the darkness and creating a very romantic atmosphere. Looking out over all of Nagasaki from the observatory, you can take in the mountains, sea, and city all at once, highlighting Nagasaki's unique terrain and charm.

    Once hailed as one of the “World’s Three Great Night Views,” the night view from Nagasaki’s Mt. Inasayama was definitely the most breathtaking visual feast of the entire trip.

    Getting to the summit isn’t very straightforward. You first need to take a bus to the area near the shrine, then transfer to the ropeway up the mountain. It can feel a little nerve-racking to find your way in the dim light when everything around you is pitch-black, but there are actually plenty of other visitors along the way, so it’s quite safe as long as you follow the crowd. As the ropeway slowly rises, the view opens up as well.

    The moment you finally step onto the Mt. Inasayama Observatory, the scenery before you instantly makes it clear that its world-class reputation is well deserved. The brilliant lights from countless homes blend perfectly with the bay’s distinctive landscape, making the entire city look as though it has been covered with a sparkling carpet of jewels. The stunning, mesmerizing night view goes straight to the heart and is definitely a grand finale not to be missed on a trip to Nagasaki.

    Mt. Inasayama, one of the world's top three night views.

    Just for that reputation, even after finally making the long journey and spending the whole day on the road, I still really wanted to come at night.

    It was around 8 p.m. We were clearly still downtown when I suddenly told my friend I really wanted to go to Mt. Inasayama. And then we actually went. Totally crazy. I love being a crazy person who just goes whenever I feel like it.

    Even though we probably stayed up there for less than 20 minutes, I was still glad we came. Otherwise, after going home, I probably would've cried about not coming, haha.

    But rather than taking the ropeway up the mountain, what I actually long for more is riding motorcycles with a group of people to see the night view together.
    (Too bad I don't have any friends 😢

    Look, there's a heart in the distance. For these few photos, all the hardship along the way started turning into excitement once we got on the ropeway?

    In the end, we just barely caught the last ropeway down. It was so nerve-racking and thrilling because we almost got stranded on the mountain, hahaha.

    There were actually a lot of taxi drivers up there, though. It seems like there must be good money in it.

    But sorry, I only had enough money for the ropeway, haha, and I get carsick easily.

    Night views...
    I've never really understood what's so great about them.
    They're just bright lights. Wouldn't looking at the stars be better?
    But I still really liked this impulsive trip.

    But that's okay. This trip was meant for checking places off my list and being a crazy person anyway? If I'm worried I'll regret something, I'll do it first and regret it afterward.
    That's how I see it.

    If you come to Nagasaki, you definitely shouldn’t miss Mt. Inasayama Observatory! Take the ropeway up to the 333-meter summit, and you’ll be greeted with a stunning 360-degree view.
    During the day, you can see Nagasaki Bay, Unzen, Amakusa, and the Goto Islands in the distance. At night, it becomes truly breathtaking, with countless lights spread across the mountains and sea like jewels scattered over the earth.
    No wonder Nagasaki’s night view was once chosen as one of the “New Three Great Night Views of the World.” Sitting at the observatory with a gentle breeze, watching the whole city slowly light up, I honestly couldn’t help thinking, “This trip was absolutely worth it!”

    You can see the night view of Nagasaki City from the mountaintop observatory. Nagasaki is built on hills, so you can watch the lights stretch up the slopes. The lights reflecting on the bay make the whole scene so romantic!
