If your computer only supports WEP encryption, but the wireless network uses WPA, you will not be able to connect to the network. However, most wireless networks can be configured to use WEP security or no security, which will allow you to connect. The trade-off is that the network becomes less secure. WEP encryption is possible to defeat, and turning off security will allow anyone connected to the network to view all data traffic, including private information. A better option may be to purchase a wireless adapter that supports WPA encryption. WPA was developed to fix the flaws of WEP, and is much stronger.
As long as the router you are trying to connect with supports -b or -g you will be fine. There is no difference between Japan and the US where 802.11 standards are concerned.

You just need to set a security key and you are ready to go. You might need to read the user's manual for some technical details because different brands are using different interfaces for such things.
Setting up your router's wireless security is the best way to prevent other people from using your wireless Internet connection.
