Who invented Japanese sumo wrestling?
There is no one person who is recorded as the inventor of sumo
wrestling, as it is an ancient Japanese sport that traces back
centuries with no record of its originators. Professional sumo,
which can still be seen today, can trace its roots back to the Edo
Period in Japan's history, which lasted from 1603 to 1868. The
first professional sumo tournaments were held in 1684. It is
believed that professional sumo wrestling came about as an
alternate source of income for the samurai.
