There was a similar image in National Geographic a few months back that pointed it out. The cause? Fishing vessels. No, I'm serious. The waters off southern Japan are the most heavily fished in the world.

Another interesting thing about that area. See the no-pollution area just above it (and no-light area, except for one spot, in the other image)? That's not water. That's North Korea.
