Internet
There are a couple of ways to use the internet in Japan, but if you are reading this page, you're probably on top of things.
Internet cafes are easy to find - they usually have up-to-date equipment, a fast connection and some young Japanese men passed out in front of a role playing game. A signing up fee is often required. After that, it generally costs one hundred yen for fifteen minutes. Internet cafes also offer printing services and in some cases, CD burning. Other things such as Messenger, might be limited. Most places have a range of discounts and a free drink policy. So, it is possible to spend fifteen minutes drinking glass after glass of Coke then head to the exit, feeling a pinch of remorse.
Another option is to set up an internet connection in your apartment. Here, there are two possibilities worth considering. Firstly, if you live in an apartment it may be that your complex has a shared internet connection. If it does, notices should be posted around the building. This method can be cheap and easy.
If this isn't possible, information on different service providers (ISPs) can be found in the computer section of electrical shops such as Joshin or Midori Denki. Speed and price are usually the main considerations. Make sure that the place where you live is able to receive services, too - some apartments, for example, cannot get fibre optics. The internet service provider should be able to give advice on this.
Usually, a phone line from NTT is necessary if you want to set up a connection. The ISP will sometimes get in touch with NTT on your behalf. Once that has been organised you will receive a modem from the service provider. After that, getting online should be straightforward.
Payment is generally made through a convenience store, or taken directly from your account. You will then get two bills a month, one from your ISP and another for the phone line from NTT. Many of the ISPs also have good deals on phone call charges when using an 'Internet provider phone' service. Rates for calling overseas can be competitive, so it is worthwhile to look into this when installing your line.
In recent months there has been a move towards fiber optic internet connections. They are much faster than broadband, it's possible to recieve TV through the cables and at the moment there are lots of special offers such as free installation of the line. Post a question in the forums if you want to find out more.
Japan is well known for being a technologically advanced country. However, as far as computers are concerned, it isn't that different to the west.
