Kuchi ga Karui (口が軽い - Having a Big Mouth)

Kuchi ga Karui

People who have a big mouth can be described as 'kuchi ga karui' (口が軽い) in Japanese.

Since 'kuchi' (口) means "mouth" and 'karui' (軽い) means "light," the literal meaning of 'kuchi ga karui' is "one's mouth is light."

Here, the Chinese character 軽 is used in terms such as 'karuhazumi' (軽はずみ) and 'keisotsu' (軽率), both of which means "rash" or "thoughtless".

From this, it is thought that 'kuchi ga karui' came to mean "people who talk a lot rashly."
