Really welcoming staff and a relaxed learning style. I cannot recommend them enough.
Their lessons focus on giving opportunities to speak in a friendly way with a relaxed pace (which I really enjoy) as I just need to learn Japanese in my day-to-day life to get around Tokyo.
They also offer Kids, and Young Adult / Teens Japanese Lessons which is unique. I havent enrolled my kids yet - but am planning on it during the summer!
Cannot recommend Mika Sensei enough!
Full Disclosure: I made an account on Sunnypages just to review them. That's how much I loved it!
