noun
A navigational instrument that shows direction; synonymous with 羅針盤 (らしんばん) but less common in modern usage.
船には羅針儀が備え付けられている。
A compass is installed on the ship.
Loanword from English, widely used in modern Japanese for both drawing and navigational compasses.
Compound of 羅針 (らしん, 'compass needle') and 儀 (ぎ, 'instrument'). The exact historical derivation is uncertain, but the spelling is conventionally associated with navigational instruments.
