Wasōbon is a type of book that comes from Japan. It's different from regular books because the pages are folded in half instead of being bound together in a book cover. The word "wasōbon" actually comes from three different words: "wa" which means Japan, "sō" which means ancient, and "bon" which means book.
So, what makes wasōbon so special? Well, they're usually made by hand and have really beautiful illustrations, drawings, or calligraphy on every page. People in Japan used to use wasōbon as a way to read and study really important things like religious texts, historical accounts, and poetry.
When you open a wasōbon, it's kind of like opening a really big card or small poster, because the pages flip upwards instead of to the side like a regular book. It's a neat way to look at things and appreciate the beauty of each individual page.
Overall, wasōbon are cool because they're a traditional type of book from Japan that are still made and appreciated today. They're like little treasures that you can hold in your hands and explore.
