A shipwreck from a failed Mongolian invasion of Japan in the 13th century has been discovered by archaeologists working at the underwater Takashima Kozaki site.
Researchers from the University of the Ryukyus and the Matsuura city board of education said it was the second shipwreck from the invasion ordered by Kublai Khan. Three other potential wrecks have also been found but are yet to be confirmed, archaeology professor Yoshifumi Ikeda told the Asahi Shimbun.
