Complete set of 6 volumes on Japan's Natural Treasures. Publisher: Kodansha List Price: 29,800 yen A valuable resource published in 1984. The original case is not included. The books have been stored at home for a long time, so there is some wear and tear due to age, but the condition is relatively good. (Please check the photos for details.) I am not considering selling individual volumes, and I prefer to sell the set. Price negotiations are possible within a reasonable range. Please feel free to ask any questions. Please purchase only if you understand that these are used items. Thank you for your understanding.
