Kaiten (manned suicide torpedo)
Historical term referring to the manned suicide torpedoes used by the Imperial Japanese Navy during World War II. Not used in modern military contexts.

Standard kanji spelling for both the literary 'changing the world' sense and the historical torpedo name.
Variant kanji form using 廻 instead of 回; less common but attested.
Composed of 回 (turn, revolve) and 天 (heaven, sky, world). The literal meaning 'turning heaven' developed into the figurative sense of changing the world or reversing a situation. The WWII torpedo name draws on the same kanji, evoking a desperate attempt to turn the tide of war.
