Well I just went to the Japanese Amazon site and ordered it.
If you click on the link provided above, then look to the right and there's an orange button (where the usual "add to cart") button is on the Amazon.com website.
On the next page you'll see a list of things that similar customers bought and a little button that says "Would you like to see this page in English?" Click on that and from then on half of the information is in English and half is in Japanese.
Proceed to checkout, log in (I had to create a new account, it didn't recognize my amazon.com password for some reason - strange as I shop at amazon.ca, .com and .co.uk using the same login and password) and then you might be asked for an address - don't start filling out the form, instead click on the "International" link and enter an address there.
On the next page, suddenly everything was in Japanese again except for my address, I clicked the wrong button and the next page was in English, telling me to choose an address for shipping, or billing (I can't remember which), so I did. After that I entered my credit card details and then got the usual final page with a summary of everything (I think the total cost was 4,700 yen - which is roughly $47) and I clicked "Place Order" and that was that. So now, hopefully, in 4 to 6 weeks I should receive my copy.
Of course, the whole thing might be in Japanese, which would be funny; as your unofficial guinea pig on this one, I'll let everyone know all the dvd details as soon as it arrives.
Sayonara.
