Otemon is the eastern gateway into the Imperial palace in Tokyo.
During the time of the Samurai this was called Edo-jo, and was the Tokugawa Shogun's castle in Tokyo.
Otemon is the gateway that was placed in the hands of the Ogaki-han to control and protect. It is believed that the founder of Masaki Ryu, Masaki Tarodayu Toshimitsu may have spent some time working at this gateway
