There are no regular meetups, and the concentration of interested people might be low. But what I say to this is, where there are two rationalists willing to meet up, there's fun to be had! So 遠慮なく, please contact me personally, especially if you live at a reasonable distance and are able to come to 新宿区 or 文京区 (which is where I live). I am more than willing to meet with you even if there are just two of us. And if there are more of us, I will coordinate. I don't use Facebook, so talk to me at ukesapkurisu@gmail.com (but writing the first six letters of this e-mail address in reverse order) - よろしく, Chris
