Only baby phrases. Certainly not anything that could be used in Air Traffic Control!
I do know that "hikoki" means "airplane" though.
One thing I noticed in Japan that was different than in other countries is that ATC seemed to be speaking English to everyone, even the Japanese pilots. This differs from other foreign countries I've flown in where they seem to use the native language with native pilots. For example, in Mexico they speak Spanish if the pilot starts out in Spanish. It is the same in Quebec and in Russia. I haven't had much international experience but that is what I have observed in my small exposure.
