I don't know of a way to do that.
Can you buy Voodoo3 or TNT2 cards where you live?
The newer cards have TV-out jacks.

I found some sites that sell converters.
I don't know if they will ship to where you live or not.

Generally you can only output to TV in 640x400 mode or lower res. This is due to fact that US tv's follow NTSC (525 line) standard and cannot lock to higher rez's. Quality isn't so hot either.

If you want quality large screen output at 800x600 or higher rez you're going to spend $$$ on LCD projector or large computer monitor.

This is case where you get what you pay for. Cheap solutions give bad looking video, oh they work ok, but is NOT what you really want. Good looking stuff for presentation/teaching is NOT cheap!

First of all the VGA output is a digital signal, and the TV uses an analog signal.  You can get a converter which is an external box which will convert the signal to analog for your TV, but there is another problem.  As Mark touch on, the units that are (for the most part) sold in the US will output to NTSC standards that are used primarily in the United States.  I doubt that Japan (assuming that is where you are) is using NTSC, but is probably using PAL, which is a different standard used in Europe and other places.  Your TV output has to be matched to your country and also matched to your graphics card.  Some higher end graphics card manufacturers (ATI, Matrox) have add-on cards for their cards.  The first thing I would
do is check with graphics card manufacturer.

Mark is also right, that you get what you pay for.  
If you are looking just for presentation purposes, than the LCD projectors and panels will allow you to use the higher quality digital output and present that, without converting it to a TV signal.  There are high end converters available, which will require a specific configuration for your country, probably the replacement of your graphics board, and a daughter board with that that will do video output.

sweston, let me correct you. VGA is an ANALOG signal from 0-5V, There are 3 channels R, G, & B with Sync provided separately. NTSC is a composite signal with color encoded as a phase shift of the 3.58Mhz chrominance signal superimposed on the intensity signal.

Converting RGB/Sync into RS-170 (baseband) video is not hard and many cheap adapters are available for it. However NTSC monitors only are spec'd to have 525 lines. Thus any video resolution from your computer that varies widely from this horizontal frequency will NOT work. 640x400 is sufficiently close (and under) that it will generally work. 800x600 is over and it, and higher, video resolutions simply cannot be locked into by the TV. In some cases this can even damage the TV's because the horizontal retrace is used to generate the high voltage (2nd anode) and the flyback is designed with a high Q and does *NOT* like operation at other that 15,750Hz (525 lines * 30 frames/second).

As sweston pointed out there are different video standards in different parts of the world. You'll find cheap adapters that will convert to the lowest common denominator. If you want high res video you'll have to get a scan converter or a higher end monitor.

Mark,
Yeah, I blew that.  Both VGA and NTSC are analog signals, which makes conversion quite a lot easier.
