Welcome, Kay!
That's awesome that you want to teach English in Japan! I'm deaf and I lived in Japan for 11 years. So, I don't know a whole lot about teaching in Japan but I do know the education system very well and of course general knowledge about Japan.
Are you planning on immersing yourself into the deaf culture in Japan? I highly recommend it. There's many events and such that are great experiences and you'll be able to make friends who might even be in a similar situation as yourself.
Oh and although you're teaching English, learn Japanese cause you're definitely going to need it despite what people say.
Anyways, feel free to PM me if you have any questions about Japan, I'd love to chat with you and I'm all for recommending stuff.
