I'm looking for advice on finding a research topic to work on for my master's degree in the near future. I'm currently working on my graduation thesis, which is a Russian translation and commentary of "The structure of the Japanese language" by Kuno Susumu. Because of it, I have taken a keen interest in the grammar of Japanese and I intend to make that language my field of study in the future as well, but so far I haven't been able to find a suitable topic. What are some prominent issues in Japanese linguistics nowadays? What are some issues that you personally consider interesting and worth researching? I am personally interested in the study of dialects and focus my current search on works and articles dealing with dialectology, so any suggestions regarding that would be especially welcome.
Thanks in advance!
