Senganen was constructed in 1658 by the wealthy Shimazu Clan, one of the most powerful feudal clans during the Edo Period (1603-1867). The Shimazu ruled the Satsuma domain (present day Kagoshima) for almost 700 years until the end of the feudal age in 1868. They continued to be influential into the modern era as some of the earliest adopters of Western science and technology.
