Wao! Are you serious? If you want to study English, I may study together. But, once you start using your English, keep it! Otherwise, it is hard to get accustomed to learning English in Japan. This is because without using English, we can manage everything as long as we stay in the domestic.
Sorry, I may use little bit difficult English. You can check your unknown words in English dictionary.
Maybe, we can talk later on screen.
