Hour of the Rat [12pm] (Ne no koku), from the series "The Twelve Hours in Yoshiwara (Seiro juni toki tsuzuki)"

Kitagawa Utamaro's Hour of the Rat (12 p.m.) (Ne no koku), from the series The Twelve Hours in Yoshiwara (Seiro juni toki tsuzuki), is in the Art Institute of Chicago (artwork 23982). Like the other sheets in the series, the design takes one of the twelve traditional Japanese double-hours, here the Hour of the Rat, and assigns it a scene from the daily life of the Yoshiwara. The Hour of the Rat traditionally corresponds to roughly 11 p.m. to 1 a.m., the dead of night, when the licensed quarter's nocturnal activity is at its height for some functions and its quietest for others. Utamaro's choice of subject for this hour, whether an interior scene with a courtesan and an attendant, an after-hours conversation, or a moment of solitary preparation, conveys the rhythm of the great Yoshiwara houses across a 24-hour cycle. The Twelve Hours in Yoshiwara is therefore far more than a decorative series: it is a structured ethnography of the pleasure quarter, in which Utamaro's named and unnamed women act out the temporal logic of their professional world. Stylistically the print belongs to Utamaro's mature Edo bijin-ga, with refined keyblock drawing, restrained nishiki-e color, and a half- or three-quarter-length figural composition that throws hair, collar, and facial expression into relief. The Art Institute of Chicago's holding preserves the Hour of the Rat for researchers tracing the social organization of the Yoshiwara and the way ukiyo-e represented private space within the licensed quarter. For collectors of Utamaro, the Seiro juni toki tsuzuki is among the essential series, and the Hour of the Rat sheet is one of its most quietly observant moments.
