Honesty and Sincerity in Chinese / Japanese...

至誠 is the idea that you enter into something with the utmost sincerity and fidelity. Ideas such as devotion, honesty, and “one's true heart” are also contained in this word.

至誠 is a universal word as the Chinese, Japanese Kanji, and Korean Hanja are all identical.

誠 means truth, faith, fidelity, sincerity, trust, and/or confidence.

As a single-character wall scroll, this suggests that you believe “honesty is the best policy,” as your personal philosophy.

This is also a virtue of the Samurai Warrior

信 is another character that expresses the idea of honesty.

It can also mean truth, faith, belief in, fidelity, sincerity, trust, and/or confidence.

Some have included this in the list for the Bushido, although “makoto” is probably more common/popular.

Note: In some contexts, this character can mean a letter (mail), news, or envoy. However, alone, it will generally be read with the honesty-meaning.

虚実 is a Japanese word that means “falsehood [and] truth” or “fiction [and] fact.”

This concept is used in warfare, gameplay, and martial arts strategies. 虚実 can be a strategy of real and/or deceptive moves. This gets to some Sun Tzu Art of War stuff where in warfare a strategic move is either a real and serious move or it is a deceptive blow.

Let's explore each character in more depth:

虚 was originally written 虛 (there is a very subtle difference in the strokes at the bottom of the character) and means unpreparedness, falsehood, emptiness, void, abstract theory, empty or unoccupied, diffident or timid, false, humble or modest, virtual, or in vain.
In the Buddhist context, 虛 represents the Pali/Sanskrit word “śūnya,” meaning empty, vacant, unreal, unsubstantial, untrue, space, humble, or in vain.
In ancient Eastern/Chinese astronomy, 虛 represents the “Emptiness” constellation (one of the 28 mansions in the sky).

実 was originally 實 in Chinese (they currently write it as 实 in Simplified Chinese) with the meaning, truth, reality, sincerity, honesty, fidelity, and substance.
The Buddhist context is similar, adding real, true, honest, really, solid, definitely, sincere, solid, fixed, full, to fill, fruit, kernel, verily, in fact, the supreme fact, or ultimate reality to the definition.
