Uma Ichi (Horse market) from "Guide to Famous Spots of Edo Vol.6"
(Japanese book)
Uma Ichi was a horse market that was held in mid-December every year. Traders would bring 100-150 nanbukoma horses aged two or three from the Nanbu domain to trade at the market. In Yabunouchi, there were three horse dealerships which worked for the stables of the Nanbu clan. The horse market used to be held in three locations, which were Fuchū Rokusho-no-miya, Asakusa, and Azabujūban, but it ceased being held in Fuchū Rokusho-no-miya Shrine during the Kyōho years (1716-1736), and it was subsequently held only in Asakusa Yabunouchi and Azabujūban. The location of the horse market pictured is in what is today Hanakawado 2 chōme, Taitō-ku.
