What airport are you flying into?
Most people are probably going to be flying into the Tokyo Narita Airport. How familiar is everyone with Japan's rail system, and rail passes?
[collapse=Subway/Train Information]Basically, before you go, you can choose to buy a foreigners-only rail pass. This allows you to ride all JR (Japan Rail) trains for free, throughout Japan. That includes almost all their bullet trains as well (but not the very fastest ones). Japan Rail is one of the biggest Japanese train companies, and they have service to almost everywhere.
If you're going to be sight-seeing Japan outside of Tokyo, it's a must-have. If you're just going within Tokyo, rail tickets are pretty cheap from one spot to the other (couple of bucks each way at the most). But you have to get the foreigners-only rail pass BEFORE you travel to Japan. You cannot buy them within Japan.
There are many sites to buy them from (as well as most travel agents), like
this one. They're pricy, but if you're going outside Tokyo on the bullet trains (Osaka and Kyoto are amazing, Osaka was my favourite spot in Japan when I was last there), it'll save you a **** ton of money. Bullet trains are amazing, expensive, and fast, and this lets you ride them for free.
Before you go to Japan, you purchase a voucher (usually mailed to you after you order it). Once in Japan, you can exchange this voucher for the rail pass, which you should keep with your passport at all times.
(technically, you're legally required to have your passport on you at all times, or you may be deported. In practice, though, this is almost never enforced, unless you get busted by the police for something)
If you're flying into Narita (as I suspect most will be, since the tournament's in Tokyo), there's a Japan Rail line that goes straight from the airport to all the major stations. You have to book a seat on that train, but if you have the pass, it's free. You don't have to book seats for any other trains, even the bullet trains (unless you pay a **** ton for 1st class).

Here's the Tokyo subway map (
alt). Trust me, it's much simpler than it looks. Each different colour represents a different rail company (which compete with each other to keep prices low, yay Japan). JR is the brack-and-white one, that circles around through the major districts (like Akihabara, Ikebukuro, and Shibuya). Bullet trains aren't on this map.
When you ride a train, you'll prepay a ticket when you go through the entrance to the station, and then pay the difference (if any) when you get off at your stop. You pay more the farther you go, and if you're transferring to a different line, you'll have to pay when you exit one company's section and again when you enter the other's. The prices are listed when you prepay the ticket, so you don't have to worry about misjudging or anything.
ex. You leave your hotel in Ikebukuro, and want to weeaboo it up in Akiba (Akihabara). You get on the rail station right next to your hotel (90% of everything important in Tokyo is a 2-5 minute walk from a rail station, especially hotels). At the JR ticket stiles, you go to the far-right or far-left (varies per station, but there's almost always bi-lingual signs) for the walk through. You show your pass to the agent and jsut walk through for free, and then get on the next train leaving for Akiba (there'll be like four spots in the station for you to get on).[/collapse]
Any word on cheap tickets?
