Prince Shotoku's globe

Size and shape, when and where(find)
Prince shotoku's globe has been transmitted to underground stones in Tokyo-dori in Hyogo prefecture Taiko town. And the size of about a softball with a diameter of 9.7 centimeters. This is from the Edo period. It was discovered 1200 years after the time of Prince shotoku. The globe can be confirmed up to Antarctica and Mu continent. How made and why made As a result of scientific analysis, this is made of lime and the technique of plastering is used. Prince shotoku's globe is made of stone. This globe can't made without the help of such material. And Prince shotoku inherited the knowledge left by the supercritcal civilization of the Mu continent, probably made this globe.

History
Approximately 1400 years ago, at that time East Asia did not even know the root of Earth as a circle. Moreover, it is not only Europe, Asia, Africa. The geographies of the areas that were first clarified after the Great Voyage age, such as the two continents (discovered in 1492) and Antarctica (discovered in 1820), are accurately made.Surely Prince Shotoku left super ancient civilization in the Mu continent era. In the world map of Europe at that time, there was a custom to write a aerial  continent on the position of Antarctica in order to balance with the northern hemisphere's land.Because I wanted to inherit knowledge in some way I wonder if I made this globe. 

Paradox
It is thought that this globe was made in that era based on the latest knowledge of Western origin, around the middle of the Edo era. '''As scientist though, the prince shotoku's not made of prince shotoku's globe. Because only it has been dedicated to the temple of prince shotoku'''

What people think about it
What was the source of the medium that Prince Shotoku could make the globe? There was nothing to check such as aircrafts and helicopters, but how did the globe complete?
