The city of Nagasaki is another major port on Japan’s southernmost main island. As with Hiroshima, Nagasaki also has its own peace memorial. The city also has a handful of temples and shrines that are worth checking out if you’re staying in the area for a while. Among these, you’ll find one of only a few shrines connected to China’s legendary Confucius. Fans of urban exploration should definitely check out Gunkanjima (Battleship Island) for some amazing structural ruins.
