This is a uchiwa (Japanese fan) sold at the AKB48 concert held on September 13, 2009, at the Fuji-Q Highland Sound Conifer. During this concert, "River" and "Kimi no koto ga Suki Dakara" were performed for the first time. This is a rare wooden uchiwa sold at that concert. It is believed to be quite scarce. Of course, it is unopened and unused.
