Hakodate, with a population of 320,000 lies at the southern point of the Japanese island of Hokkaido. In 1859 it was among the five Japanese towns first opened for outside trade, representing the gateway to the outside world. Hakodate is also the traditional starting point for trips to Hokkaido, which can be reached either by ferry or by train through the underwater tunnel constructed in 1988. This Japanese port is also famous for its star-shaped fort.
