力 — Power, strength, force
Cultural Background
One of the most fundamental kanji in Japanese, 力 represents raw physical power and ability. Its simple two-stroke form is derived from a pictograph of a flexed arm, making it one of the oldest and most recognizable characters. In Japanese martial arts, 力 is central to concepts like 力技 (chikarawaza — power technique) and is deeply embedded in the cultural understanding of strength.
Modern Usage
Extremely common in everyday Japanese. Found in words like 能力 (nouryoku — ability), 努力 (doryoku — effort), 協力 (kyouryoku — cooperation), and 電力 (denryoku — electric power). Used across all contexts from casual to formal.

This kanji embodies the idea that true strength comes from perseverance.

In samurai philosophy, 剛 represents unwavering resolve. The character is commonly used in male given names, reflecting its association with masculine fortitude.

Common Mistakes to Avoid
男 means “Male, man” — not strength
Often mistakenly chosen by those wanting a "strength" tattoo. While 男 contains the 力 radical, it specifically means "male/man" — not strength. Getting this tattooed when you meant "strength" would be an embarrassing and permanent mistake.
カ means “Katakana character for 'ka'” — not strength
The katakana カ looks remarkably similar to the kanji 力 (chikara/strength). However, カ is simply a phonetic character with no meaning on its own. A poorly written 力 can easily be mistaken for カ, which would look nonsensical as a tattoo.
These are the most common mistakes — but context-specific errors are harder to catch. The kanji for “inner strength” vs “physical strength” vs “strength of will” each require different characters. A wrong choice isn't always obvious until a native speaker sees it.

What is the most common kanji for strength?
力 (chikara) is the most commonly used and universally recognized kanji for strength in Japanese. With only 2 strokes, it's simple, elegant, and unmistakable in meaning. It's the go-to choice for those who want a clean, powerful symbol.
Which kanji for strength is best for a tattoo?

Is it offensive to get a Japanese kanji tattoo?
Getting a kanji tattoo is not inherently offensive, but it requires respect and accuracy. The main risks are choosing the wrong character, poor calligraphy, or displaying cultural ignorance. Always verify your chosen kanji with a native speaker or professional translation service, and choose a tattoo artist experienced with Japanese characters.
How do I make sure my kanji tattoo is correct?
First, research the exact meaning and potential alternate readings of your chosen kanji. Second, have it verified by a native Japanese speaker — not just a dictionary lookup. Third, check that the font or calligraphy style is authentic. Services like inkanji provide AI-powered verification with cultural context to help ensure accuracy.
What's the difference between 力 and 強 for strength?
力 (chikara) represents raw power, force, and ability — think physical strength and energy. 強 (tsuyoi) represents being strong, tough, and resilient — more about the quality of being strong rather than the force itself. In English, 力 is closer to "power/force" while 強 is closer to "strong/tough."
