Hello, I have been teaching Japanese (and English) online and cafe around Yachioyo- city, chiba. If you are interested in taking lessons, feel free to contact me and also I am thinking about having some small group lessons at cafe. I know there are so many international parties and so on but most of the time people are willing to talk in English and maybe because of your job there are not much chances to practice Japanese.. etc. I am sure you want to learn Japanese too so that you will be able to make more friends, a lot easier to make a living in Japan!
