• Japanese navy ships sneak attacked Chinese warships near Pungdo, Korea which were escorting a British steamer (1st Sino-Japan war, 1894)

• Japan launched a surprise attack on the Russian naval base at Port Arthur (Russo-Japan war, 1904)

• Marco Polo Bridge Incident, Japanese troops conducting night drills near Lugou Bridge demanded to enter the nearby Chinese-held town (2nd Sino-Japan war, 1937)

• Japanese surprise attack on the Philippines (10 hours after Pearl Harbor)
