blackberry (2)

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).

One thing you may realise when you are travelling is that your Blackberry gets very good usage. Whether it's surfing the web, checking emails or calling back home - all drain on the battery. Instead of digging around looking for the right adaptor and plug to stick it in, why not take a spare battery so that you can just plug and go?
