I'm selling this item because I bought it on Mercari but no longer use it. There is some staining on the side, and it shows signs of use. There are likely no markings inside, but I apologize in advance if I missed any. - Title: Kobun Jotatsu (Classical Japanese Mastery) - Author: Masaki Nakamitsu - Publisher: Z-KAI - Price: 1,000 yen - ISBN: 978-4860662875
