Um...20 year old ALTs would be a disaster.
A 20 year old guy, put into a situation where every single 16-18 year old girl in the school thinks you're the coolest person they've ever met. haha, oookay...
Last year, I met a kid who was 18 and on a student exchange. I couldn't imagine a better situation for an 18 year old guy and he pretty much agreed. heh...
Anyways, keep in mind I'm a 26 year old currently working in a public high school... an age gap seems like a necessity, at the very least from the employer's point of view if not for the ALT's sanity/legal situation...
I took an ALT position a few months back for 230,000 a month (no reductions) on a short term contract. Just trying it out.. I can definitely see where something like your website would be handy. But, and I mean no offense, I'd be leery of ponying up ¥5000 yen for this. Sometimes it's hard to believe a website with no track record that they're actually providing a service. Then again, a ¥5000 yen gamble to get a sweet job might be worth it.
Anyways, I also don't really feel like working at a HS again after this contract so not so useful for me.

Oh yeah, as has been discussed to death in another thread, good luck actually getting a VISA with only college transcripts. I think what he meant was that he showed his college transcripts to Nova to get hired (the company didn't require a degree) and used his marriage visa to stay in Japan. Either that, or he was in Japan some years ago. Or both.
It is virtually impossible to go work in Japan degree-less, unless you're married, doing working holiday visa, or have years of prior provable ESL experience. (Specialist of Humanities and Instructor visas both require the Degree or Experience, the two visas issued for work in conversation schools and public schools).
Sorry to beat a dead horse, but it seems impossible to kill this "can work in Japan without a degree" idea.
