Tokyo is a highly-populated, fast-paced, expensive mega-city from the future, which can make it quite a daunting place to visit. Not many Japanese people speak English (and if they do, are often too shy to say much), so the first tip is: on the flight over, memorize some basic Japanese phrases. You probably know 'konnichiwa' (hello!) and 'thank you' ('arigato') already, but if you're feeling really clever, add 'Where is the train station/toilet/hotel' ('eki/oh-te-rai/hoteru wa doko deska?') to your Japanese skills.
