How do you say “billionaire” or “super rich” in Japanese? Let’s look at 億万長者 and 大金持ち!
| Japanese | Reading | Meaning |
|---|---|---|
| 億万長者 | okumanchousha | billionaire / multi-millionaire |
| 大金持ち | ookuramochi / ooganemochi | very wealthy person / rich person |
| お金持ち | okanemochi | wealthy person (general) |
億万長者: Billionaire
億万長者 (okumanchousha) literally means “a person with hundreds of millions” (億 = 100 million, 万 = 10,000, 長者 = wealthy person). It’s used for billionaires or extremely wealthy people:
- 彼は億万長者だ。 — He’s a billionaire.
- 億万長者になる夢がある。 — I have a dream of becoming a billionaire.
- 宝くじで億万長者になった。 — She became a billionaire (multi-millionaire) from the lottery.
大金持ち: Very Rich Person
大金持ち (ooganemochi) means someone very wealthy — a “big money person.” It’s less specific than 億万長者 and just means “loaded” or “super rich”:
- あの家族は大金持ちだ。 — That family is super rich.
- 大金持ちと結婚したい。 — I want to marry someone very wealthy.
- 大金持ちになったら何がしたい? — What would you do if you became super rich?
