契約を更新する

You’ll mostly see this in adult life. You use it as a standard verb phrase. You can say 契約を更新したい when you want to stay in your flat. Or 契約を更新したくない if you’re ready to move on. It’s very common in business and real estate. Just pair it with the thing you are renewing. It’s a solid, reliable phrase that makes you sound like a responsible adult.

Use this when talking to your landlord or boss. It’s perfect for discussing your phone plan or gym membership. If you’re a freelance worker, you’ll use this every time a project ends. It’s also used in sports when a player stays with a team. Basically, if there’s a signed paper involved, this is your go-to phrase. It feels professional and clear.

Don’t use this for personal relationships. Telling your partner you want to 契約を更新する for another year is a great way to get dumped. It’s too cold for friendships. Also, don't use it for simple promises. If you promised to buy coffee, you don't 'renew' that promise. Use it only for formal, documented agreements. Keep it out of the 'casual drinks' conversation unless you're joking.

In Japan, renewing an apartment lease is a big deal. Most leases last two years. When you renew, you often have to pay a 更新料 (renewal fee). This is usually one month's rent. It can be a shock to your bank account! This cultural quirk makes the phrase feel a bit heavy for many people. It’s a moment of financial planning and decision-making.

You might hear 契約更新 (keiyaku koushin) which is just the noun form. 自動更新 (jidou koushin) means 'automatic renewal.' This is what happens with your Netflix or Spotify. If you want to change the terms, you’d use 契約を変更する (keiyaku o henkou suru) instead. Knowing these variations helps you navigate the fine print of Japanese life.
