対策
たいさく·taisaku
Meaning
countermeasure; measure; strategy; preparation
Nuance & Usage
対策 refers to measures taken to deal with or prevent a problem. 対策を立てる (taisaku wo tateru) means 'to devise countermeasures.' 試験対策 (shiken taisaku) means 'exam preparation.' 安全対策 (anzen taisaku) means 'safety measures.' 地震対策 (jishin taisaku) means 'earthquake preparedness.' It is action-oriented — not just thinking about a problem, but planning concrete steps to address it.
Common Mistakes
Learners sometimes confuse 対策 with 対応 (taiou — response/handling). 対策 is about planned, proactive measures (before or in anticipation of a problem), while 対応 is about responding or reacting (often in real-time). 地震対策 is preparation before an earthquake; 地震への対応 is how you respond when one happens. The verb is 対策を立てる or 対策を取る, not 対策する (though this is sometimes heard casually).
