The tech sounds vaguely somewhat like the smart bra Microsoft has been working on—minus the emotional overeating tracking bit. Or perhaps Nintendo's Love Tester.

But as NicoNico reports, the True Love Tester is currently not for sale. But! If you purchase over 5,000 yen (about US$50) worth of Ravijour lingerie, you can enter to win a chance to test it out at hotels in six different cities (you pick the city!) across Japan. Five lucky couples will be selected.

So, yes, this is part of a promotional campaign. It's also the first time a bra like this has been developed. For science!
