Sounds about as reliable as the folks who a few years back claim to have found the real Mt. Sinai and actual evidence of the Exodus (which archaeologists have been searching for fruitlessly for over a hundred years) over in Saudi Arabia. Of course, the Saudis refuse to allow anyone in to the area which is near the border so no one can confirm this or even verify that these blokes actually were there in the first place. Or how about all the claims about Noah's Ark up on Mt. Ararat. If you believe all the accounts, it has been found on all sides of the mountain both intact and broken apart. Of course, no one has actual evidence because: a) the Soviets destroyed the photos; b) the guy who took the photos fell into a crevasse on the way down the mountain; c) the Turkish authorities won't allow anyone to climb back up the mountain because of "security problems".

Of course there is no evidence for any of this and no reason to believe these wannabe discoverers. Most of the big finds in history have already been made and a lot of latter day explorers who want to make a big name for themselves are only too eager to jump on a poor lead or simply make up a hoax themselves if they think it can give them their 15 minutes of fame. The supposed find of Jesus' tomb by James Cameron and Jacobovici is in the same league. Don't believe the hype, not in those cases and not in this one either. The fact that this supposed Japanese A-bomb is said to have been exploded on a remote island now occupied by one of the most secretive and repressive regimes around is just too perfect to keep people from confirming or discounting the claim. Given the complete lack of evidence of any sort that Japan was engaged in a nuclear program, combined with the lack of evidence for the claim, is enough to reject it in my book.

Don't believe the hype!
