Moving along, while abroad in Japan the necessity of a cell phone is a lot bigger than in the U.S. (as in, I can survive without one here in the U.S. and in Japan... I doubt it.)As a student living abroad a cellphone would probably be a necessity simply as peace of mind and so that your parents can easily get contact you. I'd definitely get one.
Based on your situation I would suggest getting a softbank prepaid phone. They cost about 5000 yen for the handset and credit can be bought in 3000 and 5000 yen increments. As incoming calls are free, unlimited mail costs just 300 yen/month, and credit being valid for 60 days, with minimal calling you can easily limit your phone costs to 23000 yen for the entire year, which is pretty much as cheap as you can go.

So, what I want to know is if I should get a cell phone here in the U.S. and then take it abroad with me (specifically iPhone).This is a possibility but i will be very expensive if you intend to roam on a US carrier. Alternatively you could bring a US phone and get a Japanese Sim card, but if you are interested in the iphone it would probably be better to just get one in Japan and then just pay the cancellation fee on your contract (expensive) when you end up leaving.
If I should buy a cell phone in Japan, in what way and what will the process be like?It depends on what type of phone you will be getting but at the most basic they need passport and an address in Japan for a prepaid phone. For contract phones you will need alien registration, a bank account, and might need a minimum valid length of your visa.
some further comments:
Japan has its own radio frequency for cellphones, so only Japanese cellphones would work in Japan, i.e. those from abroad will not work in Japan.Japan has 3g networks that run on a 2100 mhz frequency. The iphone 3g, 3gs, and many other foreign phones will work on this frequency but you need to check your phone specs to be sure.
the older 8gb version is sold for nearly half the price of what they cost abroad.I don't think the 8gb version is still available, but the newer 16gb 3gs is free with a two year contract.
There are three major cellphone carriers in Japan: docomo, AU, and softbank (and lately, a fourth player called willcom is in the business too). The only carrier that actually provides information in English is softbank, who also sell the iphone btw. All the other carriers are in Japanese only.There's more like 5 carries. Docomo, Softbank, and Au are the 3 major ones, with Willcom and EM mobile as newer entrants. Btw, docomo, au, and willcom also have english pages. And au might be worth looking into as they offer 50% discounts on their services to students.

At the end of a two year contract the costs of the old and new system tend to even out. BTW, the standard contract is 2 years (actually 26 months). You can cancel at any time but there are cancellation fees up to the completion of your contract.
Please choose a phone wisely, because you will probably be stuck with the same model for the first 6 months you use it.Yes, with contract phones you are pretty much stuck with them for the length of the contract if you don't want to pay heavy cancellation fees. But this should read 26 months, not 6 months to avoid any fees.
