Translation guide
WWII is an abbreviation for World War II. In Japanese, it is most commonly referred to as 第二次世界大戦 (Dainiji Sekai Taisen), literally 'the Second World War'. This is the standard formal term. In casual contexts, the abbreviated form 第二次大戦 is sometimes used. When referring to the war in relation to Japan, the term 太平洋戦争 (Taiheiyō Sensō, 'Pacific War') is often used, though this specifically denotes the conflict between Japan and the Allies from 1941 to 1945. Be aware that 大東亜戦争 (Daitōa Sensō, 'Greater East Asia War') is a historical term used during the war and is now considered politically charged.
