also: りょくば
noun
force field
Refers to a protective or energy barrier, often in science fiction or speculative contexts.
宇宙船は力場で守られていた。
The spaceship was protected by a force field.
Compound of 力 (power, force) and 場 (field, place). The reading りきば uses the go-on reading of 力, while りょくば uses the kan-on reading. The exact origin is uncertain, but it likely arose as a translation of the English term 'force field' in science fiction contexts.
