Book Off () is Japan’s biggest chain of second hand bookstores. It is operated by Book Off Corporation Limited. The first Book Off store opened in May, 1990. The first franchisee Book Off store opened in Nov, 1991. The success of the business expanded to 917 stores in Japan and 14 stores abroad (8 in US, 3 in France, 2 in Korea, and 1 in Canada). Book Off sells books including comic books, magazines, and novels, and also sells CDs, DVDs, and Game software. Books are grouped by genres, writers, and prices. The overseas Book Off stores sell second hand books from Japan and also from its own country. Book Off not only sells the second hand books, but also buys the books from customers. For that reason Book Off’s theme copy is “お売りください” which means “Please, sell us your book”. The company uses this copy rather than ”We buy your book” to show respect to customers.
