The name Faithful and Honest in Chinese / Japanese...

信義 is a word often used to describe a person with an honest and loyal reputation.

Simply put, this applies to somebody you can trust (with your life).

In Chinese, this is often defined as good faith, honor, trust, and justice.
In Korean, this word means fidelity, truthfulness, or faithfulness.
In Japanese: faith, fidelity, and loyalty. It's also a Japanese male given name when pronounced “Nobuyoshi.”

誠実 is the Japanese version of integrity which can also be defined as a combination of “sincere, honest, and faithful.”

Some may also define this as “loyal” or “loyalty.” In some contexts, it can mean “genuine.” Yes, all of this meaning in just one Japanese word!

忠 is the simplest way to write the word loyalty in Chinese and Japanese.

A single character like this leaves the meaning open. But alone, a Chinese or Japanese person would think of loyalty to duty or loyalty to one's master (in ancient times). I suppose that it could be loyalty to your boss or company in this day in age.

忠 can also mean fidelity or faithfulness.

This can also be romanized as “chung.”

篤實 means sincere, solid, and faithful.
