Marco Polo's Zipangu really the Philippines?

A new study by author Setsuko Matoba proposes the theory that the island of Zipangu made famous in The Travels of Marco Polo may not have been Japan, as believed, but the Philippines.

The theory appears in Matoba's book Zipangu and Japan, published in August 2007 by Yoshikawa Kobunkan Inc.

The Venetian explorer talked about the island in the 13th century, declaring it "a land that was laden with gold." His stories were collected and later published in the 14th century, possibly creating discrepancies in place names and locations.
