I taught English in a Japanese Junior high and elementary school. The government makes the textbooks with input from senior teachers and they're all inexpensive paperbacks. It makes much more sense when I consider the gigantic expensive hardcover textbooks I would get as a kid. They were quickly outdated and occasionally filled with obscene writing from previous students.
