I took the exam this fiscal year. This is a perfect, full set for the national exam. I bought them at TSUTAYA for about 17,000 yen, but due to work, I had to go out of prefecture for an extended period and left this set at home. I couldn't use them, so I reluctantly took special courses and studied online. Of these reference books, I only took the "Kokushi Navi" (National Exam Navigator) with me on the exam day. They are all new. The textbook for the practical training was surprisingly useful as many questions came from it, so I think it's very good. It's the latest textbook from October 2025! I studied with this at school, so there are some notes written in it. I researched extensively online before purchasing these reference books, so I believe they will be very helpful for the Certified Care Worker national exam. They cover topics like the Long-Term Care Insurance Act, caregiving techniques, and dementia care, and I think they are versatile enough to be useful in your work as well, so it wouldn't hurt to have them. In fact, if you can internalize all of these reference books from now on, I think you have almost a 100% chance of passing. *This is a full set.* It cannot be sold separately, and as a set, it is already priced at the lowest possible price, including room for negotiation. It's first come, first served, no reservations. This is a new, unused, latest edition, and I believe it's a very, very good deal. I am also listing this on other auction sites. While there are no further price reductions, the price may increase or the item may become unavailable. The current price is the lowest starting price. I sincerely wish you success in passing the 2027 exam. The red underlay is a free bonus. For an additional 1500 yen, I can also include the exam questions from the January 25, 2026 exam, if you would like a copy. Of course, it is already marked with correct/incorrect answers and scores in pencil. Thank you for reading to the end. *For those who purchase now, I will include the exam papers, which normally cost 1500 yen, for free. This includes approximately 80 pages for the morning and afternoon ABC parts.* I cannot offer any further discounts, but this sale will continue until early March. You will find that the actual exam questions are quite different. Please take advantage of this opportunity! Please understand that there may be initial scratches from the bookstore before purchase. I have kept them carefully.
