If weâre talking about communities using English to conduct the discussions, the grammar questions section of the Japanese Language Stack Exchange can get pretty specific and knowledgeable, but it can also be rather hit and miss with beginner questions that arenât very interesting from a linguistic perspective. I usually just skim through it every once in a while to find the topics that interest me.
With regards to journals, I follow the Journal of East Asian Linguistics, which regularly contains articles on Japanese, but I also enjoy reading about other languages from time to time.
Great recommendations. I already have Tsujimuraâs books, 100% vouch for them. It helps that she uses the same theoretical foundation Iâve internalized for a while now (generative grammar).
I recommend looking up Japanese Linguistics professors or co-authors of other linguistics works youâve read to find more resources. I canât remember other basics, but if youâve read all of Tsujimuraâs books, you probably already have a good foundation.
I donât know about any other communities or forums, please share if you find others! If youâd like to start Japanese linguistics discussions on here though, I would definitely participate and Iâm sure others would as well.
Linguistics isnât my field so I canât offer any specific resources, but the Google Scholar Citation search is great for finding current materials on a topic. Take a reference you already know about, such as the Tsujimura books, search for it, and click the âCited Byâ link. Works better the more fundamental (and widely cited) your starting point is.
