I had hard time experiencing the entrance examination to enter Todai's graduate school, so I may understand it better than high school or undergraduate students who are looking to experiencing the exam the first time. Come to me and we can share all the difficulties with each other.
I am also welcoming smaller students and workers who want to speak English fluently and confidently. At the end of the day, we will all realize that English or any other non-native languages of yours is just a mean to help us communicate with others, then become a global citizen. Do not be afraid of speaking it loudly.
