On 12 October 1492, after several months at sea, Christopher Columbus arrived on the coast of the OTL Wakayama Prefecture, in Japan. The single rather large POD in this history, is the lack of the Americas, leaving Europe and Africa directly across the AtlantoPacific from Eastern Asia. Rather than the predictions of Eratosthenes and Ptolemy, it was the predictions such as that of Martin Von Behaim in his 1492 Erdapfel (the oldest surviving globe), which was followed by Columbus on his fateful voyage, which proved to be correct. In OTL this roughly means eliminating both American continents and their associated islands, including Greenland and moving 20 degrees west to 160 degrees west.
