Mito Kōmon
Mito Kōmon (水戸黄門) is a Japanese jidaigeki or period drama that has been on prime-time television since 1969. The title character is the historic Tokugawa Mitsukuni, former vice-shogun and retired second daimyo of the Mito Domain. In the guise of Mitsuemon, a retired crêpe merchant from Echigo, he roams the realm with two samurai retainers, fun-loving Sasaki Sukesaburō (Suke-san) and studious Atsumi Kakunoshin (Kaku-san). An episode typically starts with some injustice perpetrated by a corrupt official, wealthy merchant or gangster; the travelers arrive incognito, discover the injustice and quietly investigate it; and the episode concludes with a brawl in which the unarmed, disguised protagonists better a crowd of samurai and gangsters, culminating with the presentation of the inrō that reveals the hero's identity.
