I already posted this in the resources thread, but I'm posting it here as well, because I suspect more advanced learners/teachers on this board don't go there often to look for new sites.
I've just started a Japanese-learning blog for intermediate to advanced learners of Japanese. It's called Before Breakfast, and you can find it here:
beforebreakfast.net: 日本語を朝飯前にするウェブサイト
My site is
not for beginners; reading ability for hiragana and katakana (and basic kanji) is assumed. It's always seemed to me that too many sites out there are tailored to absolute beginners (and never give enough information) or they're tailored to super-advanced learners (and the information is never in an easy-to-digest form).
In contrast, my site's purpose is to provide interesting tidbits about advanced Japanese in a format that can be readily understood by intermediate Japanese speakers, hence helping them up to the next level.
I hope you'll visit, comment, and learn something!
