In Japan, the word ‘celebrity(セレブ) ‘ is commonly used, but the meaning is slightly different.
We often use the word only in the sense of “rich man.”
It is thought that if we say “rich man(金持ち)” directly, it sounds like a sarcasm.
Therefore, ‘celebrity(セレブ)’ came to be used instead of ‘rich man(金持ち)’ in some cases.
Japanese TV show sometimes introduce rich people as celebrities, but they often are not well-known.
