Wow mate, truly awesome! I wish to do something like this in the next few years, following your journal now! Amazing photos too!
May I suggest when you go to Macau that you guys do the Bungee Jump? It's the highest in the world and it's a truly remarkable experience. If you'd like some advise on places to go and see for HK/Macau over the space of a week please do let me know as we pretty much covered all the areas in about 6 days!
You are gonna love Japan I'm sure of it!
Enjoy
