Kumiko (Rinko Kikuchi) is bored by her life. As a twenty-something Tokyo “office lady,” she sees herself stuck in a dead-end job. She quietly detests the demands and intrusiveness of her condescending boss, Mr. Sakagami (Nobuyuke Katsube), and the incessant phone calls of her nagging mother (voiced by Yumiko Hioki). She’s even loath to address such everyday activities as keeping up her apartment, collecting her mail or spending time with a onetime acquaintance, Michi (Kanako Higashi). In fact, the only things that seem to give Kumiko any pleasure are caring for her pet rabbit, Bunzo, and her pursuit of an unusual hobby – treasure hunting.
