This is a 23-volume set of Shogakukan's "Shonen Shojo Nihon no Rekishi" (Japanese History for Boys and Girls) manga series, which teaches Japanese history. The set includes all 21 volumes of the main series, plus two supplementary books: a biographical dictionary and a historical site/museum dictionary. A panoramic timeline is also included as a bonus (see image 10). Based on meticulous historical research, the series recreates the period from the Paleolithic era to the present day in dynamic manga format. It's a full-fledged educational manga that allows children to enjoy learning and acquire accurate knowledge as their first introduction to history. It's easy for elementary school students to read, yet the content is authentic. It can be used for a long time, from junior high school entrance exams to university entrance exams. Learning through manga stories helps children understand the flow of history and the characters involved. Especially for children preparing for junior high school entrance exams, history can be challenging due to the many difficult kanji characters, and memorizing everything can be tough. This book, which allows them to grasp the flow of history and events through manga, will be very helpful. 【Condition】 Purchased for my daughter's junior high school entrance exams. She seems to have read it once, but she hardly read it after the exams were over. Therefore, the outer box has some wear and tear, such as scratches and dents, due to aging, but the books themselves have almost no damage, and the contents are in near-new condition. Please note that some of the books have slight discoloration on the spine due to aging, as they were kept on a bookshelf. This is a used item that has been read by a child, so please refrain from purchasing if you are looking for a perfect product. We cannot accept claims or returns, so please take a good look at the images and make your judgment. If you have any questions, please ask. 【Shipping】 We plan to ship via Rakuraku Mercari courier service.
