The computer itself must have a wireless adapter to connect to wireless networks. It is also necessary to have a wireless router, which must support the same kind of wireless communication as the adapter(a,b,g,n), although an ad-hoc network can be set up with only two computers and no router.
If you are talking about building of wireless network. Then you need a wireless router and a wireless network adapter (if you have a laptop you might not need it). If you have a desktop you rather will have to purchase a wireless network adapter. Pay attention to what kind of wireless network you are going to build. It can be a, b, g, and n types.
When selecting a wireless network adapter for a wireless network, it is important to be aware of the technology and capabilities of the router. The latest technology used in wireless routers is 802.11N, which is backward compatible with older networking protocols such as 802.11g and 802.b. However, the performance of signal transfers of a wireless network adapter is limited by the technology used in the router. For example, a wireless-N adapter will not reach its full Mbps speeds of data transfer when connected to a wireless-G router.

You might have to. Not many B-type routers support WPA. Check the router manual to see if it's capable of WPA.
It depends on the type of wifi adapter. The 3 most common ones are b, g, and n. First check the type of adapter your laptop has. Mine, for example, is wireless n. If you have a wireless g adapter then upgrading to a wireless n adapter would be a good choice. Alternatively, upgrading you're router to wireless n (if you're laptop is wireless n) would work too.
Wireless B is the 802.11b standard.Any Wireless B routerr has a bandwidth of 11Mbps
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.
no...you can buy things like wireless internet cards or drill holes in the wall to hardwire it but having just a wireless thing would be easiest
A wireless only router sends out a radio signal to all the devices, B, G and N bands. The computer/devices have to have a wirless card/dongle to work though. It only has the one ethernet port for the modem to connect to it.A Wired only router is one that only has ethernet ports connecting it to the computers/devices. There is no radio transmitter in it.Most routers have both now, usually 4 ethernet ports and the wireless radio as one, so you can connect wireless or wired devices to the router at the same time.An example world be my older tower doesn't have a wireless card and I don't want to buy a USB wireless device so I can just use the ethernet cable to connect to the router while my Laptop connects wirelessly.
All wireless adapters are the same.
Assuming this other computer is not located near your router (in which case you would just run a cable) the first thing you need is to make sure this computer has a working wireless card that is compatible with your router. There are four flavors of wireless - A, B, G, and N. A is rarely used these days and not compatible with the rest. N cards and routers are usually backward compatible with B and G, but check. G is the most widely available. Once you have a computer with a compatible card that you know is working, just connect it like you did your first computer that's on the network. In some cases, you may have to power down all of your devices and then re-boot "from the wall out" - first the modem, then the router, finally the computer(s). It's that simple. Most wireless router are configured by default to accept a number of simultaneous connections. If for some reason the above fails, check your computer and make sure the wireless card is activated (Device Manager) and receiving - you should see some kind of indicator on your computer or the card depending on your equipment. Still no connection? Check the settings on your router. Did you enable security (WEP, WPA, etc) or turn off broadcasting? You'll need to make those settings on you new computer. Specifics of this can be involved and depend on which method you use.
