Important/Influential language teaching books.

HI everyone, I thought it would be nice to share language teaching books (or other good to know books) that you consider important for "teaching in Japan". I didn't see any previous posts on this topic and thought it would be nice to share. Although I have read various books on teaching English, I'm sure there are many I'm not aware of/haven't read yet. Here are a couple of mine.

"How Languages are Learned" by Lightbown and Spada

"Making Communicative Language Teaching Happen" by Lee and VanPatten

"Language Files: Materials for an Introduction to Language and Linguistics" by Department of Linguistics

General book for people coming to Japan to teach:

"how to teach English" by Jeremy Harmer (Maybe this is outdated but it's what I had nearly 20 years ago)

“What every EFL teacher should know” by Paul Nation

For ALT's:

"Native Inquiry into Language Teacher Identity" and "Team Teachers in Japan: Beliefs, Identities, and Emotions" by Takeaki Hiratsuka (Relatively recent publications and pricey)

For teaching young learners:

"Teaching Young Learners English" by Shin and Crandall

EDIT: thank you everyone for sharing. I’ve saved this post so I can return to it.
