How to say "diversification" in Japanese

• 多様化たようかCommon
  noun, suru verb, intransitive verbThe common, general-purpose word for something becoming more varied. When English 'diversification' simply means that variety is increasing — in tastes, markets, or society — this is the safest choice.
• 万状ばんじょう
  nounAt bottom this means multifariousness — a state of great variety, many different kinds at once — rather than a process of diversifying, so it is seldom the word you want for 'diversification'.
• 経営多角化けいえいたかくか
  noun, suru verbDiversification as a corporate strategy: a company expanding into new lines of business. The element 経営 ('management') makes the business setting explicit, so this belongs to management and economics writing.
• 多角化たかくか
  noun, suru verbDiversification in the sense of branching out into several distinct fields or directions. In practice it is chiefly a business term, the shorter counterpart of 経営多角化, for a company broadening beyond its original line.
  その会社かいしゃは市場しじょうを拡大かくだいするために最近さいきんの製品せいひんの多角化たかくかを図はかった。↗

  The firm has recently diversified its products so as to extend its market.
• 多角経営たかくけいえい
  no-adjectiveDiversified management: the practice, or state, of running a company in several business lines at once. Choose this when you mean the strategy itself rather than the act or process of diversifying.

Use 多様化 for the general sense of things becoming more varied; 多角化, 経営多角化 and 多角経営 for corporate diversification; 万状 really means multifariousness and is seldom the word you want.
