Although brown bears no longer traipse around Tokyo, their fossils dated between 340,000 and 20,000 years old have been discovered in several locations on Honshu Island, researchers noted in a new report, published Tuesday (Aug. 3) in the journal Royal Society Open Science. That raises the questions of when and how the Honshu bears first got to the island, but unfortunately, there s little fossil evidence of the beasts migration.
