Tokyo (30)

Japan's mobile phone system is not compatible with most non-Japanese phones. This includes Blackberrys and tri-region phones. Make sure you don't get caught short by checking to see if your phone gives you a signal when you get off the plane. If not, you are able to rent a phone at the airport (it's easier here as you can return it just before you head home and the language barrier is not an issue).

Instead of bankrupting yourself on a taxi fom the airport to your hotel, get one of the reliable and regular limousine buses from the airport directly to your hotel.

Business cards can be critical - particularly in cultures such as Japan and the rest of Asia. Always keep some business cards aside away from your main store, just in case (like me) you forget it one day. At least you've got some spare.

On your own in Tokyo? Search out large office blocks, daytime or night time, there's usually a food court either at ground or upper level. Japan can be expensive and this is an easy and inexpensive way to eat out alone. Don't worry about the language, there are the plastic plates to point out.
