Sukkiri Wakaru (Clearly Understand) Bookkeeping for the Japanese Bookkeeping Association (Nissho Boki) Level 2: Commercial Bookkeeping, 13th Edition (Price: ¥1540) Sukkiri Wakaru (Clearly Understand) Bookkeeping for the Japanese Bookkeeping Association (Nissho Boki) Level 2: Industrial Bookkeeping, 9th Edition (Price: ¥1540) I'm selling these because I passed the exam and no longer need them. They show signs of use, but there's almost no writing in them, and I think they're perfectly usable! If you need it, I can also share my study methods, tips, and the textbooks I used when I passed. Feel free to ask when you purchase.
