"Eiken Grade Pre-1 Pass-through Words in Order of Appearance, Supported by the Ministry of Education, Culture, Sports, Science and Technology" Obunsha Price: ¥1650 I bought this new and used it for only one month. I've marked some words with red circles as shown in the image, but they are erasable friction pen marks. Thanks to this book, I was able to pass the exam. #Obunsha #book #language/English
