Mitsumura Tosho Publishing Co., Ltd. (Location: Shinagawa-ku, Tokyo; President: Naoki Yoshida), a publisher of textbooks for elementary, junior high, and high schools, is launching a new line of stationery and merchandise inspired by their textbooks. Targeted not only at students currently using textbooks but also at all adults who grew up with them, these items were developed to help people cherish nostalgic memories of 'the me of the past.' We hope this line will remind customers of the excitement they felt when first opening a textbook upon entering elementary school, and bring that excitement to their daily lives as adults. For the time being, these products will be sold exclusively at the following event venues, although online sales are being considered for the future.
