I personally believe most Japanese people who want to learn English are proficient in written English. All you need is just practice and someone to practice conversing with is what I'm happy to provide.
I'm currently helping many Japanese friends of mine at Waseda University practice their conversational English. I'm also assisting someone with TOEIC test preparation.
The pace and setting of the lesson will depend on the student's preference and I can cater to all levels.
I'm an easy-going relaxed person who likes socialising and I look forward to meeting you! :)
