A summary textbook specifically for Japanese language study. - Title: Summary of Four Subjects: Japanese Language - Publisher: Yotsuya Otsuka - ISBN: 978-4-907-7017-1 - Colors: Orange/White/Blue It was almost unused. Thank you for looking. Price reduced. I remember it was from around the time I was in 4th grade of elementary school, so I think it would be good for review. Please purchase only if you understand.
