Make sure you have money in shinjiku . there will be lots of things you want to buy and they all add up. its also fairly hard to spot out the atms over there. its not the oriential style city, this is a big brands fashion type city. :)
take a camera if you wanna get a few snaps of the great atmosphere or the famous crossing where tokyo drift was filmed.
transportation is great in japan squishy but great. every 3 or so minutes theres usually a train or bus to take you in the right direction. the maps can get a little confusing though.
