This is a set of textbooks and past question collections, but you can also purchase them individually. Please consult in the comments. "Basic World Heritage 100: World Heritage Certification Level 3 Official Textbook" World Heritage Academy / World Heritage Certification Office Price: ¥1450 ↓ No writing. In good condition. "World Heritage Certification Level 3 & 4 Official Past Questions Collection 2018 Edition" World Heritage Certification Office / NPO World Heritage Academy Price: ¥1200 ↓ Slightly worn. No writing. Although the year is old, there isn't much change in the questions for the World Heritage Certification, so I think it's usable. This is a textbook published by the official World Heritage Certification. It's recommended for those who don't take the World Heritage Certification but want to know what Japan's World Heritage sites are like. It has explanations with photos of beautiful scenery, etc. #WorldHeritageAcademy #WorldHeritageCertificationOffice #Book #Geography/Geography/Maps
