How much do I need to travel to Japan in a tight budget trip? including Airfare, hotel and food?

Does Anybody can help me? I wanna travel to Japan, but I guess everybody think it is expensive and i wanna prove them it is not. got any idea for cheap airfares , food and stay?

Here is a guess:
$1000 for a round trip ticket
$100 per day for all expenses: lodging, transport, food, fun

Japan used to be much more expensive (relative terms) ten or so years ago.

go to Yahoo travel and you can get airfare prices. You will need at least $3k (ball park figure). $1k for airfare, $2k for hotels and daily expenses. You could stay in youth hostels and capsule hotels. Travel light.

If you go on stand-by you can usually pick up a really cheap flight.

While in Japan you will need a minimum of $100 for accomodation, transport and meals.

There are plenty of cheap hotels, ryokans (traditional Japanese Inns), and hostels all over Japan. I booked a room in Tokyo for two people last week for 4800 Yen. Do a web search...

If you want to eat inexpensively in Japan it is very easy to do. There is no shortage of cheap noodle places where you can get a large bowl of noodles and sometimes rice for 400 yen. Cheaper still are bento boxes which you can get practically everywhere.

Beware of taxis and buying drinks in bars and restaurants. They are way overpriced. Most expensive of all are rock melons on sale in supermarkets which are priced at 35,000 Yen!!
