Hello everyone!
I've just compiled a list of threads outside of /nihongo/ that might be interesting to Japanese visitors of 4-ch.
Since I don't know what Japanese visitors might generally be interested in, I just did a little search on everything that is somehow related to Japan or 2channel. Kinda generic, I know. ( ´−`)
There might be more threads on 4-ch that could be interesting to Japanese visitors, especially on /anime/, /manga/ and /ascii/ but I suggest you just have a look there for yourself!
Here goes:

/games/
Video games, online games, board games, mind games.
Here are just two threads directly related to the Japanese
gaming market, but you might find other threads interesting to you:

Interesting discussion about recent major developments of Japan's constitution.
Some Japanese have already contributed to this thread.

This thread may not be about Japan but since it's about some of Japan's
most important neighbours, you might be interested.
