In Japan we use the character “力(ちから-chikara or りき-riki or りょく-ryoku)” for the English word “power”. We use like this; 彼は力が強い(かれは ちからが つよい-karewa chikaraga tsuyoi). This sentence means “He has strong power”.
We have many words in which this character is contained. Here are some examples; “引力(いんりょく-inryoku)” means “Gravity”, “武力(ぶりょく-buryoku)” means “Force”, “努力(どりょく-doryoku)” means” Effort”, “知力(ちりょく-chiryoku)” means “Intelligence”, “暴力(ぼうりょく-bouryoku)” means “Violence” etc.
