Wu Hsing-wen, editor-in-chief of Publishing Industry Magazine, notes that the Tokyo Book Fair has never been that well attended, the main reason being that Japan has a highly developed system of copyright agents. Copyright trading goes on routinely within this system. Secondly, costs are high there, making exhibitions an expensive proposition and causing foreign publishers to think twice about going there.
「出版界」雜誌總編輯吳興文也指出，日本東京書展一直不太熱絡，原因是日本版權代理作業相當發達，平時就有制度的進行交易，其次是物價昂貴、書展費用太高，令國外書商卻步。
