Some Book Off chains, especially ones abroad, have various signboard designs, but still they share the symbol colors of Book Off which are yellow, blue, and red. Book Off has its mascot "Yomuyomukun (Mr. Yomu-yomu)" holding a book in his hands. "Yomu (読む)" in Japanese means "read". Another uniqueness of Book Off is the employees’ loud greeting. Employees shout “いらっしゃいませ! (irashaimase! : welcome!)” when customers enter, and "ありがとうございました! (arigatou gozaimasita! : thank you!)” when customers leave the shop. Book Off chain stores abroad also greet customers with Japanese.
