I've just finished unpacking my books and putting them on the shelf after an international move. I arranged them by topic, and it boggled my mind how I have no less than 15 books on N1/Level 1 plus 10 others on kanj, vocab, and other advanced topics. I knew I had a lot of books but I didn't realize I've hoarded this many.
I'm ashamed to admit I've hardly ever cracked the spine of most of them....
They're too good to waste, so I've decided to do a page a day. Let's see if my lazy ass can keep even that up.
On another note, my soon-to-be brother-in-law has taken up my offer to teach him Japanese via Skype. The poor guy has been stuck in the "trying to learn" phase for a couple of years now. When he becomes family, it'd greatly help matters if he could at least communicate with the in-laws. (The other happy alternative would be having the in-laws learn English, but we'll see...)
As to why his fiancée can't be the one to teach him, she kinda expects him to start practicing with her even before knowing the basics. I'm talking 「N1はN2です」 level basic. If she spoke Japanese around him I bet he could pick up a lot of stuff but they're in a long distance relationship and my SIL's English is pretty good so she has no reason to start using Japanese on him.
I was at a loss for teaching materials. The printouts I used long ago for Levels 4 and 3 have been lost and I only have N1 books in the house. However, I was pleasantly surprised to find online resources for learning Japanese have come a long way from where they were 8-10 years ago (yeah, I'm a dinosaur). Here are a couple I'm planning to use:

My favorite so far since you can toggle between Japanese and English. Audio recordings are the icing on the cake. And everything is well-organized.

This is more of a teacher's resource site that requires registration (free). 6-7 years ago I remember they had this interactive flash browser app that was a fun way to learn some basic vocabulary but I can't find it anymore. It's not very well organized and a pain to browse, but they have a lot of illustrations for making flash cards and teacher's plans for classroom activities. All kanji on the site also comes with furigana so it's easy to read for beginners (hurts my head though). Officially endorsed by the Japan Foundation.
EDIT: Found another gold mine!
https://www.erin.ne.jp/jp/index.php
Pretty cool site with lots of video skits, quizzes, and interactive vocabulary lists. The premise is about the experience of an exchange student from the UK named Erin. Uses real-world Japanese. I estimate that it requires at least late elementary level of Japanese to use effectively without a teacher. If you register, you can keep track of you progress but the content is accessible even without registering. Also officially endorsed by the Japan Foundation.
If anyone knows of other good sites for beginning Japanese, I'd like to hear about them as well.
