How to say "understandable" in Japanese

• 無理はないむりはない
  expression, i-adjectiveCovers the 'no wonder' sense: someone's action or feeling is understandable because nothing about it is unreasonable. Use it when commenting that a reaction was only natural given the circumstances.
  私にはうれしくはなかったが、ほかのあらゆるものと同おなじ様ようにトニーの価格かかくも上あがるのは無理むりはないと思おもい、同意どういした。↗

  I wasn't happy, but it seemed reasonable that his prices should go up like everything else, so I agreed.
• 無理もないむりもない
  expression, i-adjectiveSame 'no wonder' sense as 無理はない and largely interchangeable with it; the も adds a slightly softer, more sympathetic shade, as if conceding 'that would hardly be unreasonable either.'
  無理むりもないわ、はじめのうちは、そんな風ふうに感かんじるものよね。↗

  It's reasonable that you feel that way at first.
• 無理のないむりのない
  expression, prenominal modifierThe noun-modifying form: it describes a plan, pace, or approach as unforced and reasonable rather than calling a person's reaction understandable. For 'his anger is understandable,' this is seldom the word you want.
• 故なしとしないゆえなしとしない
  expression, i-adjectiveA set phrase asserting that an action or attitude was not without reason — closer to 'justified' than to plain 'understandable.' Being less common, it is seldom the word for simply saying 'I see why.'
• 無理ないむりない
  expression, i-adjectiveA shortened form of 無理はない／無理もない with the same 'no wonder' meaning; use it when you want to grant, briefly and lightly, that someone's reaction was only natural.

For the 'no wonder they felt that way' sense, pick 「無理はない」 or 「無理もない」 (or the shortened 「無理ない」); 「無理のない」 instead describes unforced plans or approaches, while 「故なしとしない」 stresses that an action was justified.
