In 1970 (Showa 45), amidst Japan's rapid economic growth, the Japan World Exposition (EXPO '70) was held in the Senri Hills of Osaka. As an event symbolizing Japan's high economic growth, it achieved over 64 million visitors with the participation of 77 countries. The entire country was enveloped in the Expo mood. 55 years later, in 2025 (Reiwa 7), the Expo will return to Osaka. This book looks back at the Osaka Expo based on the previously released "Gakken Edition Elementary School Student's Japan World Exposition," "Extra Edition Junior High Course EXPO '70 Everything," "Extra Edition High School Course World Exposition Young Guide," and the treasured photographs taken for their production. The book's structure alternates between newly written pages introducing pavilions and trivia, and reprinted pages from the magazines "Science" and "Learning" of the time, allowing those who attended, as well as those who couldn't, to relive the excitement of the Osaka Expo. ■ Special Interview with Naoki Urasawa!
