Power and Speed in Chinese / Japanese...

高速 means “high speed” or “in high gear” in Chinese and Japanese Kanji.

In old Korean Hanja, it also means “high speed” but can also be a nickname for “rapid transit.”

高速 is the best selection if you want to say “speed” in regard to your race car, race boat, or lifestyle. You need this word, which literally means “high speed,” as the Asian word for “speed” alone does not suggest whether you mean fast or slow.

力操正 is a Korean martial arts title meaning “Power Control.”

It's most often cited as one of the 8 key concepts from Tang Soo Do.

This can be pronounced in Chinese but will only be recognized by those familiar with martial arts terms.

龍馬精神虎虎生威 is an old proverb that is used to wish someone great health and success combined as a great compliment.

The meaning is “The vigor and spirit of the legendary dragon-horse and the power and prestige of the tiger.”

By giving a wall scroll like this to someone, you were either wishing or telling them that they have these qualities. There is also a suggestion of good health - at least anyone with the vigor of a dragon horse would seem to also be in good health.

This can be read as “girl power,” “woman power,” “women empowerment” or “female strength.”

女力 is kind of a strange or unofficial title in Chinese and Japanese. At least, it's not common for a wall scroll.

This should be “onna ryoku” in Japanese but I found some who suggest it should be “me riki.”

絶対的な力 is a long Japanese word that means “Absolute Power.”

By those terms, this is roughly the Japanese equivalent of “juggernaut.”

毅力 is a way to express “perseverance” with the idea of “willpower” in Chinese and old Korean Hanja. It can also mean “strong-willed.”

The first character means “strong” and “persistent,” while the second means “strength” and “power.”

大力 can mean immense physical strength or great power.

This can also act as an adjective for expressing how energetically or vigorously something is.

This can also be a given name, Dairiki, in Japanese.

悟性 means the power of understanding and insight in Chinese.

It is often associated with Neo-Confucianism. In that regard, it means to realize, perceive, or have the perception of man's true nature. It can also mean finding your soul, the soul of others, or the soul of the world. Some will translate this simply as the state of being “savvy.”

In Japanese, this is often translated as wisdom and understanding.

霊能力 is a word that means psychic power or spiritual ability in Japanese.

You may recognize the first character, 霊 (rei), is the same as the first Kanji in the word reiki. It means spirit or spiritual, but in this context can also mean psychic.
能力 can mean ability, capacity, or power.

自律 means self-discipline and self-control.

It is doing what you really want to do rather than being tossed around by your feelings like a leaf in the wind. You act instead of reacting. You get things done in an orderly and efficient way. With self-discipline, you take charge of yourself.

Not sure if this one works for a Japanese audience.

自力 is a word in Chinese, Japanese Kanji, old Korean, and Buddhist term meaning: the power within oneself; self-sufficient; by oneself; self-made; self-power; inner ability.

緩急 is often used as a Korean martial arts term, “speed control.” It's also one of the 8 key concepts of Tang Soo Do.

In other contexts, this can mean priority, pace, tempo, or slow and fast.

力 is the simplest form of “power” or “strength.”

In Japanese, it is pronounced “chikara” when used alone, and “ryoku” when used in a sentence (there are also a few other possible pronunciations of this Kanji in Japanese).

In some contexts, this can mean ability, force, physical strength, capability, and influence.

意志 is a Chinese, Korean, and Japanese word that means “determination to achieve.” It can also be translated as: will; willpower; determination; volition; intention; or intent.

In Japanese, this can also be the given name, Ishi.

意志力 is a form of willpower or self-control and is about having the determination or tenacity to keep going.

In Japanese, this is the power of will, the strength of will, volition, intention, intent, or determination.
