This is a book about the 2025 Osaka-Kansai Expo, published by Pia. It's very helpful for those planning to visit the Expo, as it provides detailed information about the Grand Roof Ring, pavilions, transportation in Osaka, and tourist attractions. I handled this book with care since I bought it, so there are no stains or scratches. I used this book as a reference to travel from Hiroshima to Shin-Osaka and then to the East Gate via the subway. At the Expo, I stayed near the Midosuji Line and enjoyed the daytime pavilions and the nighttime water show. On the third day, I went on a water cruise in Osaka and visited Dotonbori before returning home. This book was extremely useful for my Expo-related sightseeing.
