I really want to watch Biggest Loser

Greetings from Japan,
I am living in Japan, and I just heard about the show Biggest Loser. I really want to watch it... every season. However, I can't find any place to buy it, download it, or watch it.

Can anyone help me? Please tell me where I can find it on the internet, or (if you have tapes/dvds) I would be happy to pay for copies and shipping.

Any advice? Any help?
