Clear in Chinese / Japanese...

日本晴 is a Japanese Kanji title that means beautiful weather, clear and cloudless sky, or clear weather.

It's a little odd, but if you literally translated this phrase, it says, “Japanese weather,” as if that was an indication of perfect weather (maybe a little arrogant on behalf of Japan - I've experienced a monsoon there, which was unpleasant).

清 is a word that means clarity or clear in Chinese, Japanese Kanji, and old Korean Hanja.

Looking at the parts of this character, you have three splashes of water on the left, “life” on the top right, and the moon on the lower right.

Because of something Confucius said about 2500 years ago, you can imagine that this character means “live life with clarity like bright moonlight piercing pure water.” The Confucian idea is something like “Keep clear what is pure in yourself, and let your pure nature show through.” Kind of like saying, “Don't pollute your mind or body, so that they remain clear.”

This might be stretching the definition of this single Chinese character but the elements are there, and “clarity” is a powerful idea.

Korean note: Korean pronunciation is given above but this character is written with a slight difference in the "moon radical" in Korean. However, anyone who can read Korean Hanja, will understand this character with no problem (this is considered an alternate form in Korean). If you want the more standard Korean Hanja form (which is an alternate form in Chinese), just let me know.

Japanese note: When reading in Japanese, this Kanji has additional meanings of pure, purify, or cleanse (sometimes to remove demons or "exorcise"). Used more in compound words in Japanese than as a stand-alone Kanji.

青天 means clear sky and/or blue sky in Chinese and Japanese Kanji.

Sometimes this term is used in Chinese to refer to an upright and honorable official or politician (a very rare thing).

In Japanese, this can also be the name Harutaka.

晴朗 is the Chinese, Japanese Kanji, and old Korean Hanja for sunny and cloudless.

This can also mean fair, serene, clear, and bright.

This usually refers to clear weather and sunny skies.
