True, the Japanese had a different way of dealing with civilians

I suggest you google "nanking", where the Imperial Japanese soldiers
tossed infants into the air and caught them on bayonetts, raped the
women, and officers had "beheading" contests. Then talk to the
indigenous Okinawans about being herded into caves to be bombed as part
of a PR campaign, while the Emporer tried to find a way to "surrender
with honor"

See how honorable the Japanese were?
