Inasa-machi, Nagasaki City

Mt. Inasa Lights Stretching Beyond the Harbor, and Castella I Brought Along

At Mt. Inasa, city lights climb the slopes around Nagasaki Harbor. On a summer night, I took the slope car to the summit and enjoyed the view with castella in hand; in spring, I walked among about 80,000 azaleas in the park; and in winter, I rode the glass-sided ropeway and followed the harbor lights up the hillsides.

In spring, see the azaleas halfway up the mountain; in summer and winter, head to the summit for the night views. Pick a season and enjoy that day’s scenery and my travel story.

At the Mt. Inasa observatory at night, a woman in a white cardigan and pink dress gazes at a box of castella. Nagasaki Harbor and the hillside city lights spread out beyond the glass railing.

Harbor Lights Stretching into the Distance, and Castella I Brought Along

Partway through my summer trip around Kyushu, I decided to spend 2 nights in Nagasaki. My red convertible had come over by ferry from Ariake, and my friend, who’d flown in a little earlier to meet me, was riding shotgun. We’d decided to visit Mt. Inasa for the night view on our first night in Nagasaki.

When I was driving around the city, I could only catch glimpses of the harbor between buildings. We parked at Mt. Inasa’s midway car park, which holds about 400 cars, then rode the slope car up to the summit. It began operating in 2020. As we climbed slowly, more and more lights appeared outside the window, and I was already leaning toward the glass before we even reached the observatory.

At the observatory, Nagasaki Harbor opened up beyond the glass railing. The water was dark, and only the city around it glowed. Lights from homes dotted the distant hills too. I hadn’t realized the city I’d just driven through had this shape. I found myself stopping at the railing.

Blue lights lined the ground, and the benches faced the night view. I straightened my white cardigan over my pink dress and walked toward the harbor with my friend. Instead of trying to take in the whole view at once, I found it easier to follow the lights one by one—along the shore, then up the hills. My friend seemed to prefer seeing it all at once, so she stepped back from the railing to take it in.

“Those lights in the distance go higher up the hills than I expected,” I said, and my friend was looking across the harbor too. Homes line the bowl-shaped slopes around Nagasaki, giving the night view a different feel from one over a flat city. Without thinking, my eyes followed the lights higher and higher, as if I were trying to see just how far up they went.

When I opened the little box we’d picked up in town, there was one slice of castella inside. The top was golden, and the sponge was moist all the way through. I decided to take a bite before photographing the view. The sweet scent of eggs made an outdoor snack at night feel a little special.

On a clear day, you can apparently see Unzen, Amakusa, and the Goto Islands. But it was night, so the sea beyond the harbor stayed dark. I pointed out over the water and wondered aloud with my friend whether islands would be floating in that darkness by day. We promised to come back at dusk next time and watch the daylight turn into night.

After taking in the night view, we took a break in the observatory lounge. Sitting side by side, we showed each other the photos we’d taken. We’d been standing in the same place, but the harbor was at the center of my friend’s pictures, while mine were all about the hillside lights. We couldn’t believe we’d noticed such different things, and ended up laughing.

While we were in the lounge, I picked Sea Firefly for the drive back. We returned to the midway car park, and once I’d checked that my friend had fastened her seat belt in the passenger seat, I started the song. We drove down the mountain road and into the lights we’d been looking down at from above.

Local specialty

Nagasaki Castella

A moist cake from Nagasaki, made with flour, sugar, and eggs. I picked up a small box of castella in town and opened it at the summit observatory on a summer night. With the night view in front of me, even the sweet egg aroma felt extra special.

Highlights

Night Views Over the Harbor and Hillsides

The city lights climb the bowl-shaped slopes around Nagasaki Harbor. I was amazed to see the city I’d just driven through from this angle, and found myself searching for the highest lights from beside the railing.

Light at Your Feet on the Observatory Deck

The summit observatory has small lights scattered across its floor too. Enjoy the night view through the glass railing alongside the glow beneath your feet.
