Cheapest Food available?

Well... i plan on living in japan in the future($$$), might be studying there($$$) without any support and food is still a part of survival...

So can anyone give me information on cheap and fulfilling foods available in japan?

The cheapest...
At 100yen shops, you can get some instant-ramens.
At McDonald's, they sell some hamburgers for 100yen.

Cheaper...
At chain fast-food restaurants, about 300-500yen, and in the morning, "morning-set" is good, I think.

Of course, at supermarkets, especially at the evening, you can get cheaper foods.
Also some shops like bakeries, they cut the price just before closing for the day.
I can recommend you buy in the supermarkets, 100yen shops, drug-stores, NOT convenience stores, if you want to save your money.

Buy all your meat and vegetables at Hanamasa. They have by far the cheapest prices in Japan.

The convinient stores are very useful and not so bad, I love seven-eleven very much.
But almost all goods are costly about 10-50% than other discount stores
like supermarkets, 100yen shops or drug-stores.

The cheapest way is to cook for yourself. If you don't have access to any cooking area see the first response. Otherwise, just keep in mind that you'll want to cook using what Japanese people tend to use and when it's in season. So hit up the cookbooks section of a bookstore or two and start watching the cooking shows on TV. Then head to your nearest grocery store and cruise the aisles for what's cheap. Go to your kitchen and start experimenting. Repeat. You'll become a pro in no time. :)

Depends tho, my dream career has a tight schedule, i might not be able to cook xD

Yeah well your dream career doesn't pay very well either, so better start learning how to cook.
