Doujinshi.org shows nothing after 2017's doujinshi, and no manga after Rin closed.
Curious, he dosen't seem to be making any new manga that we can see but going by his twitter he has the money to travel around and enjoy plenty of good food.
I'd guess he got an artist job with some publisher and now no longer has as much free time to make ero manga as he used to. Might explain why his releases in Comic Rin stopped for a few years from mid 2009 to a final one off in 2011.
Edit: I still really want to see his Animal Ear Hot Spring manga animated one day. We've seen a few manga by other artists get animated like Emily's Creamy Pie and Akazawa Red's Namanaka Hyaku Percent.
