At 0230 hours, Japanese troops began landing on New Britain on three beachheads, two of which were defended, but in general the Japanese had little difficult overcoming the defenses. Carrier aircraft from Akagi and Kaga supported the invasion after dawn, enjoying air superiority thus losing only one pilot (Flight Petty Officer 2nd Class Isao Hiraishi) all day. As the troops entered and captured Rabaul, New Britain, Bismarck Islands, as reported by Tolai natives later, Japanese troops mutilated corpses of Australian troops with axes and bayonets.
