Pro Tip
When to use
Use this idiom when someone gives something valuable to a person who cannot appreciate it, such as giving a book to someone who doesn't read or giving a gourmet meal to someone who dislikes fine dining.
Word Origin
The idiom originates from the idea that giving gold coins (小判, koban) to a cat (猫, neko) is meaningless because the cat cannot understand or use the value of the gold. The phrase dates back to the Edo period (1603–1868) and reflects the cultural value placed on gold coins during that time.
Usage Notes
This idiom is used in both spoken and written Japanese to express the futility of giving something valuable to an unappreciative recipient. It can also be used humorously or sarcastically.
