The book cover has some minor scratches and stains, but the main body of the book is relatively clean. This book, published by Yokohama Trade News on May 31, 1979, is a historical book about Yokohama at the time of the opening of its port. It cost 5,500 yen at the time of publication, but now commands a premium price. Although the price is not fixed, even used copies sell for over 10,000 yen. A characteristic of this book is that it is composed of accounts from living witnesses at the time. There is no better reference material for learning about the history of Yokohama at the time of the port's opening. All the text has furigana (kana readings), so you can read it easily and enjoyably. The book has 387 pages.
