It was the last stage of the Boshin War, and occurred around Hakodate in the northern Japanese island of Hokkaidō. In Japanese, it is also known as the Battle of Goryokaku (五稜郭の戦い, Goryokaku no tatakai).

It was the first government to attempt to institute democracy in Japan, though voting was allowed only to the samurai caste.
