How to say "enforcement" in Japanese

• 実施じっしJLPT N3approx.Common

  The plan was put into operation.
• 強制きょうせいJLPT N1approx.Common

  Nothing can force me to give it up.

  noun, suru verb, transitive verbEnforcement as execution: carrying out or performing what has been ordered or decided, such as executing a sentence; think of it as putting an order or decision into action.

  The courts administer the law.
• 施行しこうJLPT N1approx.Common

  いつその法律ほうりつは施行しこうされますか。↗

  When will the law go into force?
• 強行きょうこうJLPT N1approx.Common
