How to say "downside" in Japanese

• 下振れしたぶれ

• マイナス面マイナスめん
  nounThe word for 'downside' meaning the negative aspect or disadvantage of a plan, decision, or situation. When 'downside' means the bad side of something rather than a downward movement, this is the word you want.
  テレビにいくつかのマイナス面まいなすめんがあるのも事実じじつである。↗

  It is true that television also has some disadvantages.

For 'downside' as the negative aspect or drawback of something, use 「マイナス面」; 「下振れ」 means a downturn or downward swing — a movement toward worse conditions — and fits only that movement sense, as in economic talk.
