Around 23 million years ago, western Japan was a coastal region of the Eurasia continent. The subducting plates, being deeper than the Eurasian plate, pulled parts of Japan which become modern Chūgoku region and Kyushu eastward, opening the Sea of Japan (simultaneously with the Sea of Okhotsk) around 15-20 million years ago, with likely freshwater lake state before the sea has rushed in.

It is most commonly used to distinguish the country's four largest islands ( Hokkaidō , Honshū , Kyūshū , and Shikokū ) from smaller islands such as the Bonin Islands and the Ryukyu Islands .
The Japanese archipelago is the result of subducting tectonic plates over several 100 million years, from the mid-Silurian (443.8 Mya) to the Pleistocene (11,700 years ago). Approximately 15,000 km (9,300 mi) of oceanic floor has passed under the Japanese archipelago in the last 450 million years, with most being fully subducted.
The making of the map was a major undertaking and the map took several years to complete. The map was not created by Fra Mauro alone, but by a team of cartographers, artists, and copyists led by him and using some of the most expensive techniques available at the time. The price of the map would have been about an average copyist's annual ...
