Japanese Words for Strength

Power / Strength / Force

The most fundamental Japanese word for strength and power. Chikara represents raw force and ability — it appears in hundreds of compound words and is one of the first kanji Japanese children learn. It can refer to physical strength, but also metaphorical power, influence, and capability.

Strong / Powerful / Resilient

The primary adjective for 'strong' in Japanese, used to describe everything from a strong person to a strong wind, a strong will, or even a strong flavor. Tsuyoi carries a sense of durability and toughness — something that can withstand adversity and remain intact.

Superhuman strength / Great physical power

A compound of 'sturdy/hard' and 'power,' gouriki describes extraordinary physical strength beyond normal human limits. Historically, gouriki referred to mountain porters in feudal Japan who carried impossibly heavy loads up steep temple paths — a testament to the awe such strength inspired.

Physical stamina / Endurance

Literally 'body power,' tairyoku refers to one's overall physical stamina and constitution. In Japan, maintaining tairyoku is considered a personal responsibility — schools emphasize physical fitness tests, and the concept is deeply tied to health, longevity, and the ability to persevere through daily challenges.

Arm strength / Brawn / Physical might

Combining 'arm' and 'power,' wanryoku specifically refers to muscular strength and brawn. While it literally describes arm strength, it's used more broadly to mean physical force or might. In Japanese culture, wanryoku alone is rarely celebrated — it's valued most when paired with wisdom and discipline.
