This is "NHK Invitation to History Volume 10: The Decisive Battle of Sekigahara" (New Compact Series). It focuses on the Battle of Sekigahara, depicting the path to Tokugawa Ieyasu's unification of the country, the events before and after the battle, and the successes and sorrows of the related warlords. It has been stored on my home bookshelf for a long time. There are slight stains on the top and edges of the book, but the pages are clean with no stains or sun damage. Please consider this item with the understanding that it is a used book.
