very true! XD
WHAT?? YOU MEAN I CANT STEAL MANA?? D: I'm kidding. XD

But for the hotels, another tip is that when you're researching them online, no matter where you decide to stay, look for a five star Westernized hotel (If you value some of your American customs XD). Also, Shinjuku is the best place to stay for any Japanese fashion/vk/etc lovers (I learned that from some of my Japanese friends and it worked out VERY well). :3 The Prince Hotel is an AMAZING hotel that can be fairly cheap (if you search it on expedia at the right time), and so is the Shinjuku Washington Hotel. Shinjuku Washington is kinda small, but most people visiting Japan aren't going to be spending majority of their time in a hotel anyway, unless they're not there for fun.

Oh, and you can buy converters in Japan for really cheap. I had to do that for my laptop. I found a really good converter at an electronic store for $2.(^^)

Tokyo isn't the only city with no street signs. Osaka and Hiroshima didn't either, so I would assume none of them do. XD
