Money in Japan in Chinese / Japanese...

錢 is the simplest way to say “money” in Chinese.

It can also mean cash, coins, or currency. It's also a surname, Qian, in China.

This also means coins in old Korean Hanja and Japanese Kanji (though they use a slightly alternate form in Japan, as seen to the right). In both Japan and Korea, this can simply mean “one cent.”

On the left side of this character is a radical, which means “gold” (or metal, depending on context).

On the right are two repeated radicals which currently mean “small” or “narrow” but used to kind of mean “tools” or “weapons.”

It's a bit of a stretch, but you could suggest that money = “gold weapons” or “gold tools” in Chinese. Many Chinese people would argue otherwise depending on what they know of or the way they understand the etymology of the right side radical. I've seen some who say it means “industrialized gold,” but I take that to mean “raw gold turned into coins.”

金 is the symbol for metal (often means gold or money) in Chinese, Korean and Japanese.

In an interesting twist, in Japanese, this Kanji can also mean “Friday.” I guess Friday is “the golden day” in Japan.

Gold / Metal is one of the five elements that ancient Chinese believed all things were composed of. These elements are also part of the cycle of Chinese astrology. Every person has both an animal sign, and one of the five elements according to the date of their birth. See also Five Elements and Chinese 12 Animals / Zodiac.
