Nostalgia.

During Japan's Edo period of isolation, Nagasaki was the only city permitted to engage in foreign trade. To this day, Nagasaki retains a rich foreign influence, inviting visitors to uncover its mysterious charm. The city boasts numerous tourist attractions, including unique offshore islands, vibrant shopping streets with an oriental flair, million-dollar night views from mountaintops, ancient shrines and hot spring resorts, and enchanting theme parks and aquariums, all contributing to Nagasaki's unique allure. The Megane Bridge, spanning the Nakashima River, is said to be Japan's oldest stone arch bridge and is one of Nagasaki's most popular tourist spots. It is called the 'Megane Bridge' because the reflection of its two arches in the water resembles a pair of glasses.
