I want to learn English and be good English speaker. — I am Japanese and Japanese spearker. I am open source software engineer, so I WRITE and READ English somehow. However I can almost not SPEAK and HEAR English. I am in Tokyo Japan. I want to learn English speak and hear skill. But I do not have place of learning English. Is there English learning spot in Tokyo, Japan? Or is there good study method of English in Japan? I want to information of these!

Medium? What is this? — In the world, there are some microblog/blog service, e.g. Twitter, and so on. I consider how I have to use medium. I am Japanese and speak/write Japanese on Twitter and so on. Japanese language has too many information per word length than other latin language. So some people says that Japanese language and/or Japanese user adapt Twitter. Because Medium have to be write long lantin (English) message, I think. So I write English to Medium as first post now.
