"The deposits have a heavy concentration of rare earths. Just one square kilometer (0.4 square mile) of deposits will be able to provide one-fifth of the current global annual consumption," said Yasuhiro Kato, an associate professor of earth science at the University of Tokyo.
The discovery was made by a team led by Kato and including researchers from the Japan Agency for Marine-Earth Science and Technology.
They found the minerals in sea mud extracted from depths of 3,500 to 6,000 meters (11,500-20,000 ft) below the ocean surface at 78 locations. One-third of the sites yielded rich contents of rare earths and the metal yttrium, Kato said in a telephone interview.
Are these deposits off the coast of Japan real? Or are they a propaganda designed to get people's minds off of Fukushima & other problems? I wonder.

We-e-ll, such rare earth minerals as gadolinium make it possible for doctors to make diagnoses of their patients with MRIs, amongst other things. The trouble is, 90% of the world's known rare earth deposits are all in China.

Did you guys know that the rare in rare earth has nothing to do with the element being rare. Rare earth minerals are really quite plentiful.
The production of rare earth oxides comes attached with a major problem: radioactive waste. The mining of the rare earths and the processing of the various elements produces large amounts of thorium as a byproduct. This material is radioactive and dangerous to human health. In China, lax environmental laws have allowed the country to build a monopoly in the market. However, now the country is looking to mitigate environmental damage from the production of rare earths, shutting down small mining operations, and raising environmental standards. www.ibtimes.com... -rare-earth-liability-or-asset.htm

Are they stupid or something In my province they just found one of the richest deposit of yttrium in the world, just because they don't own the company doesn't mean they cant share.In other words they are probably competing companys.They are in a real rush to get this new mine opened back up its' actually an old mine that was used for gold and silver extraction.A wealthy asian investor wants this mine in production by next year.( the mine in my province).
Its a shame we are still getting raw materials from the ground when there is already so much of it above ground.Not to mention tailings from other mines of the past may be rich in this mineral they never had a use for before.Go to old mines and mine the tailings.
Japan certainly has incentive to explore for a source of rare earths after China used their monopoly as a form of economic warfare back in September 2010:

Japan and the U.S would probably wanna exploit these rare mineral deposits especially if they are this common in the Sites at the Ocean Depths in the Pacific
No wonder Japan has been exploring for other sources of Rare Earths.
China produces 97 percent of the world’s rare earths, and its fast economic growth requires that more of its metals production remain at home for domestic use. But last month’s unofficial embargo on shipment of rare-earth elements to Japan in response to the detention of a Chinese fishing-boat captain whose boat collided with a Japanese patrol boat shows that for China, rare-earth metals are not only iPod ingredients but also tools of economic warfare.
