Mt. Inasayama Observatory
At 333m above sea level, this observatory stands at the top of Mt. Inasayama at the center of Nagasaki City. The observatory with a cafe and restaurant offers a view over Nagasaki Bay, Unzen, Amakusa and Goto Islands.
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!”
