Translation guide
In Japanese, the concept of a millionaire is expressed through specific terms that denote wealth and status. The most common and direct term is 億万長者 (okumanchōja), which literally means 'billionaire' but is used for 'millionaire' in the sense of a very wealthy person. Other terms vary in formality and nuance.
To refer to someone who is extremely rich, typically with assets in the millions or more.
To specify someone who possesses exactly one million units of a currency (e.g., dollars, yen).
While 'millionaire' literally means someone with a million units of currency, in Japanese, 億万長者 (okumanchōja) is the natural equivalent even though it technically means 'billionaire'. Using 百万長者 (hyakumanchōja) may sound unnatural or overly literal.
In casual conversation, 金持ち (kanemochi) is often sufficient to convey the idea of a wealthy person. Reserve 億万長者 for when you want to emphasize extreme wealth.
