EFC, congrats on the news.
You will find the whole experience in Japan somewhat different to previous lives.
Be prepared to do things differently and be aware, from day 1 what is acceptable and not acceptable behaviour. Things in Japan are a lot more formal than what we are used to in the West.
When you arrive, introduce yourself to the guys on course ahead of you and try to get as much info on the course as possible from them, they will definitely help to prevent the odd cultural faux pas.
It's pretty straightforward, so nothing to be alarmed about. Just learn the rules quickly and play the game, that's the easiest way.
There's lots of support for the guys and, in general, we all look after each other.
Good luck with it all and enjoy the experience.
