"A Grammar for 100 Million People: English Grammar for Speaking" Yasuto Onishi / Paul Macvey Price: ¥1,980 (tax included) There are markings in about 5 places with a highlighter or mechanical pencil. There may be other overlooked markings. The markings do not interfere with reading at all. The markings are scattered mainly in the first chapter of the book. I bought it at a bookstore about two months ago. It's a thick reference book, so you might use it like an encyclopedia. Available for immediate purchase. Price negotiations are possible.
