Translation guide
A person with assets worth several million units of a currency, typically dollars. In Japanese, this is expressed with specific terms for the ultra-wealthy, often using the word 億万長者 (okumanchōja) or the loanword マルチミリオネア (maruchimirionea).
Describing someone whose net worth is in the millions (often dollars).
The most common and natural Japanese term for a multimillionaire or billionaire. Literally 'person of hundreds of millions', it implies extreme wealth.

The founder of that company is a multimillionaire.
Means 'very wealthy person' or 'magnate'. It can refer to multimillionaires but is broader, covering anyone with great wealth.

Loanword from English. Used occasionally in business or media contexts, but sounds foreign and is less natural than 億万長者.

Literally 'a person with assets of several million dollars'. A clear and precise way to describe a multimillionaire in dollar terms.

General term for 'rich person'. In casual conversation, it can imply multimillionaire status without specifying the amount.
That person is a multimillionaire, you know.
Short for 'celebrity', but often used to mean a wealthy, glamorous person. Can imply multimillionaire status in a trendy context.
億万長者 specifically implies wealth in the hundreds of millions (億), making it closer to 'multimillionaire' or even 'billionaire'. 大富豪 is a broader term for 'very wealthy person' and can be used for anyone extremely rich, not necessarily a multimillionaire.
Do not translate 'multimillionaire' literally as 複数百万長者 or similar. Such phrases are not used in Japanese. Stick to 億万長者 or descriptive phrases.

彼はすごいセレブで、家が何軒もある。
