Human Academy Japanese Language Teacher Training Course - Series Name: Japanese Language Teacher Training Course - Publisher: Human Academy Includes 3 textbooks and 10 DVD boxes. I purchased this here. However, I immediately became a full-time teacher at a Japanese language school after completing the training course, and I barely had time to look at them, but I was able to pass the teaching certification exam. The grammar hasn't changed, so I think it's especially useful for those studying independently. The explanations by the Human Academy instructors are easy to understand. I'm offering it at a low price, so please consider it. There are no markings. Thank you for looking.
