You can take the ropeway to the top of the mountain.

From the observatory, you can enjoy a 360-degree panoramic view of the city of Nagasaki, including buildings in the city of Nagasaki, ships anchored at Nagasaki Port, and bridges over Nagasaki Port. Also, on clear days, you can see as far as Unzen, Amakusa, and the Goto Islands.

The night view from Sayama Observation Deck is especially beautiful and has been called the ``10 million dollar night view.'' The city lights of Nagasaki and the illuminated ships floating in Nagasaki Port are reflected in the beautiful sparkling sea, creating a magical atmosphere.
