On December 11, 1941, four trees were cut down. It is suspected that this was retaliation for the attack on Pearl Harbor by the Empire of Japan four days earlier, though this was never confirmed. In hopes of dissuading people from further attacks upon the trees during the war, they were referred to as "Oriental" flowering cherry trees for the war's duration. Suspended during World War II, the festival resumed in 1947 with the support of the Washington, D.C., Board of Trade and the D.C. Commissioners.
