Thanks for your reply Larabell !.

I am still seriously considering speaking with my Father in Law regarding contacts/work opportunities in Japan but really not sure which strategy to adopt, as said he is very much "old school", do you think it would be inappropriate if I were to write him a letter in Japanese <aided by a translator> to put across my point of view, I do speak Japanese but not to the level where I can confidently go deep enough into what I want to convey... Any thoughts welcomed.
