Mandarake Complex at Akihabara, Tokyo

Eight-floor secondhand manga and anime mega-store on Chuo-dori.

Mandarake Complex is an eight-floor secondhand treasure house dedicated to manga, anime, and Japanese subculture collectibles, occupying a jet-black building with crimson signage that has become a landmark on Chuo-dori in Sotokanda. Founded as a used manga store in 1980, Mandarake's Akihabara flagship stocks everything from vintage Showa-era goods and cels to doujinshi, figures, toys, and BJD dolls. It sits a six-minute walk from Akihabara Station.

Each floor specialises in different categories, with a buy-back counter for sellers and browsing open 365 days a year from noon to 8pm. Collectors hunt for rare Japanese Pop Antiques alongside mainstream anime merchandise, making it as rewarding for serious hunters as for casual fans. The sheer breadth suits anyone chasing a particular figure, cel, or nostalgic manga volume.

Set aside an unhurried afternoon to lose yourself across the floors, and ask staff about the buy-back counter if you have items to sell. Few places capture Akihabara's otaku spirit as completely as this.
