Mandarake is a Japanese retail corporation that operates a chain of used goods stores specializing in otaku-related items. Its stock includes manga, anime-related goods, DVDs, CDs, toys, figurines, trading cards, video games, cosplay items, animation cels, and dōjinshi. As of September 2018, toys make up 48 percent of its non-consolidated sales.
Mandarake opened its first store in 1980 as a seven-square meter used manga shop inside the Nakano Broadway shopping complex in Nakano, Tokyo. It was formally incorporated in February 1987. The Nakano Broadway store has operated continuously since its founding.
Mandarake was established by a manga artist who was a member of the Garo Trio, a group recognized in the 1970s for work published in the alternative manga magazine Garo. Furukawa built public recognition through television appearances as an appraiser of rare and vintage manga on a variety series on TV Tokyo.
Mandarake currently operates 11 retail locations and one fulfillment center across Japan, with stores in Tokyo, Utsunomiya, Sapporo, Nagoya, Osaka, Fukuoka, and Kitakyūshū. The company also runs an online storefront that ships to 83 countries. It formerly operated stores in California, Bologna, and Beijing.
On the 4th of August 2014, a vintage Tetsujin 28-go tin toy worth 250,000 yen was stolen from Mandarake Nakano. The company posted a pixelated security image of the suspect online and threatened to remove the pixelation if the item was not returned within a week. The shoplifter, Kazutoshi Iwama, was arrested on the 19th of August 2014, and later sentenced to one year of imprisonment and three years of probation.
Mandarake became a public company on the 26th of July 2000, when it was listed on Mothers. It later moved to the Second Section of the Tokyo Stock Exchange on the 1st of February 2015.
