noun
mushroom millionaire; newly rich person

Standard kanji spelling for this rare term.
Variant spelling without okurigana.
成金 is the common modern term for 'nouveau riche', while 俄か分限 is a rare, somewhat dated expression with a similar meaning.
俄か (sudden, unexpected) + 分限 (wealth, social standing). The exact historical derivation is uncertain; the term is now rare.
