Carry lots of bottled water with you! It gets incredibly hot during summer.

always wear a pair of nice shoes!you don't want to stop shopping around because of sore legs. a better way is to exercise on walking at least 1 month earlier.

American Airlines Admirals Club at Narita International Airport. All Admirals Clubs are not created equal. This one is special from the moment you walk in the door. There are many Western refinements, but you never lose the sense that you are in an Asian environment. I would not recommend spending money for a day pass at most Admirals Club. This is the lone exception. If you are around for three (3) or more hours, the pass will be well worth it. You can shower, eat, and drink. Also free wi-fi internet access for your laptop, or free access to club computers. This place cranks.
