政策を実施する

You use this phrase when you are talking about big-picture stuff. It usually follows a noun that describes a plan or a system. The most common partner is 政策 (seisaku), which means policy. The verb 実施する (jisshi suru) is the star of the show here. It means "to implement" or "to carry out." You’ll see this in news headlines about the economy, environmental rules, or education changes. If you’re at work and your boss announces a new work-from-home rule, you might hear this phrase. It’s formal, so keep it for professional or academic settings. If you use it while talking to your cat about his new diet, he might find you a bit too bureaucratic. Actually, he’d probably just ignore you anyway.

Imagine you’re scrolling through a Japanese news site like NHK or Nikkei. You’ll see headlines like "The government implemented a new economic policy." In Japanese, that’s 政府は新しい経済政策を実施した. Or maybe you’re watching a J-Drama about a tough politician. He might shout about the need to 政策を迅速に実施する (implement policies quickly). In a more modern context, think about a tech company in Tokyo. They might テレワーク政策を実施する (implement a telework policy). Even schools use it. If a university decides all classes are now on Zoom, they are オンライン授業の政策を実施している. It’s everywhere in the world of "official business."

Reach for this phrase when you want to sound informed and professional. It’s perfect for job interviews when discussing company strategies. It’s the bread and butter of university essays and JLPT B2-level reading passages. If you are debating social issues on a forum or writing a serious blog post about climate change, this is your go-to. It signals to your listener that you aren’t just talking about random actions. You are talking about structured, intentional systems. It’s the linguistic equivalent of putting on a blazer before a meeting. You can also use it in business emails to sound authoritative when discussing project rollouts.

Please, don’t use this for personal chores. If you tell your roommate, "I am going to implement the policy of washing dishes," they will think you’ve lost your mind. For personal actions, use 決める (kimeru - decide) or 守る (mamoru - follow). Also, avoid it in very casual settings. If you’re at a bar with friends, saying 政策を実施する will make you sound like a robot. It’s too heavy for light conversation. It’s like using a sledgehammer to crack a nut. Keep it for the office, the classroom, or the newsroom. Also, don't use it for physical activities like "implementing a run in the park." That’s just ジョギングする.

The most frequent error is using the wrong verb. Many people try to say 政策を作る (make a policy). While not technically wrong, it only describes the planning phase. To say you are actually doing it, you need 実施する. Another mistake is mixing up 実施 (jisshi) with 実行 (jikkou). 実行 is more about "execution" of a specific task, while 実施 is the official implementation of a system.

Using する alone is too weak for such a heavy word like 政策. It’s like wearing flip-flops with a tuxedo.

If 実施する feels too stiff, you might try 実行する (jikkou suru). This means "to carry out" and is slightly more action-oriented. It’s like the difference between "implementing" a rule and "executing" a plan. Another one is 行う (okonau), which is a general word for "to do" or "to conduct." It’s softer and more common in speech. For example, 政策を行う is perfectly fine and a bit less "lawyer-like." Then there’s 適用する (tekiyou suru), which means "to apply." You’d use this if a policy only applies to certain people, like "applying a discount policy to students."

You’ll often see this phrase modified by adverbs. 迅速に実施する (jinsoku ni - quickly implement) is a favorite of politicians who want to look busy. 試験的に実施する (shikenteki ni - implement as a trial) is common for new tech or apps. You might also see the passive form: 政策が実施される (the policy is implemented). This is very common in news reporting where the focus is on the action, not who did it. In corporate settings, you might hear 新たな政策を実施に移す (move a new policy into implementation), which adds a bit of flavor and movement to the phrase.

Is this only for government? No! Companies and organizations use it all the time for their internal rules. Is it ever used in casual speech? Rarely, unless you're being sarcastic or joking about your "personal policies." What's the difference between 政策 and 規則? 政策 is a broad policy or strategy; 規則 is a specific rule or regulation. Can I use it for a game? Yes, if you're talking about a game developer implementing a new balancing policy. Why is it so long? Japanese formal language loves multi-kanji compounds; it adds weight and clarity to the meaning. Is 実施 a noun? Yes, it's a Suru-verb, so 実施 alone is "implementation," and adding する makes it the action.
