継続する

The Japanese verb 継続する (keizoku suru) is a cornerstone of the Japanese lexicon, representing the concept of 'continuation' or 'persistence' in both formal and semi-formal contexts. At its heart, it is a suru-verb, meaning it is formed by the noun 継続 (keizoku), which translates to 'continuation' or 'sequel,' combined with the auxiliary verb する (suru), meaning 'to do.' While English speakers might simply say 'keep going' or 'continue,' keizoku suru carries a nuance of sustained effort, systematic maintenance, or the formal extension of a state or activity. It is less about the physical act of moving forward and more about the temporal persistence of an action or condition. In Japanese society, there is a profound cultural emphasis on the virtue of persistence, often encapsulated in the proverb 'Keizoku wa chikara nari' (Continuity is power). This gives the word a positive, almost moral weight when used in personal development or educational settings.

Formal Usage

In business or legal contexts, it refers to the renewal of contracts or the ongoing nature of a project. For example, 'keiyaku wo keizoku suru' means to renew or continue a contract.

Beyond the boardroom, you will encounter this word in news reports discussing economic trends, such as the 'keizoku' of a recession or a growth period. It is also a staple in the world of fitness and habit-building. If you are learning a language or going to the gym, a Japanese mentor wouldn't just tell you to 'do your best' (ganbatte); they might emphasize the importance of keizoku. The word implies a rejection of the 'quick fix' mentality, favoring instead the steady, rhythmic application of effort over time. It is important to distinguish this from the more common 'tsuzukeru.' While both mean to continue, keizoku suru is often perceived as more academic, formal, or objective. It describes the state of something remaining in effect or the conscious decision to maintain a process.

Psychological Nuance

It often implies a sense of discipline and willpower. When someone says they are 'keizoku'ing their studies, they are highlighting their consistency.

In a broader sense, keizoku suru covers the maintenance of a status quo. If a policy is being 'keizoku'ed, it means it is not being cancelled or changed. This makes it a vital word for understanding Japanese news, where administrative decisions are frequently described with this verb. The kanji themselves provide a clue to this depth: 継 (kei) means to inherit, patch, or succeed, suggesting a link between the past and the future, while 続 (zoku) means to continue or series. Together, they paint a picture of a sequence that remains unbroken, like a thread connecting different points in time. This is why the word is used for historical traditions that are 'keizoku'ed through generations.

Grammar Note

As a transitive verb, it takes the particle 'wo' (を) when you are continuing an action. As an intransitive verb, it can describe a state continuing with 'ga' (が).

Ultimately, keizoku suru is about the long game. It is the word used when discussing sustainable development (SDGs), long-term investment, and lifelong learning. It bridges the gap between a simple action and a permanent lifestyle or institutional policy. When you use this word, you are signaling that the subject is not just happening right now, but is part of a deliberate, ongoing sequence that has value because of its endurance.

Mastering the usage of 継続する (keizoku suru) requires understanding its flexibility as a Sino-Japanese (kango) verb. Unlike native Japanese verbs (wago) like tsuzukeru, keizoku suru is frequently used in written reports, formal speeches, and professional communication. It functions primarily as a transitive verb when an agent is performing an action, but it can also function intransitively when describing a phenomenon that persists. To use it correctly, you must pay close attention to the particles and the level of formality you wish to convey.

The Transitive Pattern (~を継続する)

This is the most common usage. You use the particle 'wo' to indicate what is being continued. This is often an activity, a contract, a study, or a policy.

When discussing personal habits, using keizoku suru implies a high level of dedication. While you might say 'benkyou wo tsuzukeru' to a friend, you might write 'mainichi no gakushuu wo keizoku suru' in a self-reflection essay or a job application to show your disciplined nature. The word choice itself elevates the perceived effort. It's also worth noting that keizoku can be used as a noun in compound phrases, such as 'keizoku-teki na' (continuous/sustained) or 'keizoku-sei' (continuity).

The Intransitive Pattern (~が継続する)

When a state or condition continues naturally or without a specified actor, the particle 'ga' is used. This is common in weather reports or medical descriptions.

In business Japanese (Keigo), keizoku suru is often paired with humble or honorific expressions. For instance, 'keizoku shite mairimasu' (we will continue) is a standard way to end a business proposal, showing commitment to the client. It conveys a sense of reliability and long-term partnership. In contrast, using 'tsuzukemasu' might sound a bit too casual or simplistic in a high-stakes negotiation. The word is also essential for describing legal states, such as 'keizoku chū' (currently in progress/pending), often seen in court cases or administrative processing.

Common Collocations

1. 契約を継続する (Renew a contract)
2. 調査を継続する (Continue an investigation)
3. 支援を継続する (Continue support)

Finally, consider the negative form keizoku shinai or keizoku wo chuushi suru (discontinue). In the context of subscriptions (like Netflix or a gym), you might see the phrase 'keizoku tetsuzuki' (renewal procedure). If you don't do this, your service will not 'keizoku suru.' Understanding this word helps you navigate the logistical side of living or working in Japan, from signing lease agreements to managing bank accounts. It is a verb of stability and endurance.

You will encounter 継続する (keizoku suru) in a variety of real-world settings, ranging from the highly formal to the aspirational. In Japan, the concept of 'keizoku' is deeply ingrained in the education system and the corporate world. It is not just a verb; it is a philosophy of life. If you watch NHK News or read a Japanese newspaper like the Asahi Shimbun, you will see this word daily. It is the preferred term for discussing government policies, international treaties, and economic trends. For example, when a prime minister announces that they will 'keizoku' the policies of their predecessor, it signals stability and a lack of radical change.

In the Workplace

During quarterly reviews or project meetings, managers will ask if a certain initiative should be 'keizoku'ed or terminated. It sounds more decisive and professional than the casual 'tsuzukeru.'

In the realm of self-help and education, keizoku suru is used to talk about 'the power of habit.' You'll find countless books in Japanese bookstores with '継続' in the title, offering strategies on how to keep studying or exercising. In this context, it often appears in the phrase 'keizoku wa chikara nari' (continuing is power/persistence pays off). Teachers use this phrase to encourage students who are struggling with difficult subjects like math or English. It suggests that talent is less important than the ability to keep going day after day. If you are a student in Japan, you will likely hear your sensei use this word when talking about your long-term goals.

In Healthcare

Doctors use 'keizoku' when discussing treatment plans. They might say 'kusuri no fukuyou wo keizoku shite kudasai' (please continue taking your medication). This usage is precise and technical.

Another common place to hear this word is in the sports world. Athletes often talk about 'keizoku' in interviews, referring to their training regimens. A marathon runner might describe the 'keizoku' of their pace, or a baseball player might talk about 'keizoku'ing their daily practice routine. In these cases, it implies a gritty, unglamorous, but essential part of success. It is also used in the context of TV shows or manga series. If a series is popular, it might be 'keizoku'ed for another season. Fans will look for news about whether their favorite show will 'keizoku' or end.

Legal and Administrative

When you receive a notice from your landlord or a utility company, look for 'keizoku.' It often refers to the automatic renewal of a service or lease.

In summary, keizoku suru is a word that spans the gap between technical jargon and motivational speech. Whether it's a doctor's advice, a CEO's strategy, or a teacher's encouragement, the word signals a commitment to the passage of time and the maintenance of effort. Understanding its various contexts will significantly improve your ability to navigate professional and social life in Japan.

While 継続する (keizoku suru) is a versatile word, English speakers often struggle with its formality and its relationship with similar verbs like tsuzukeru and tsuzuku. The most common mistake is using keizoku suru in a context that is too casual, making the speaker sound unnaturally stiff or robotic. For example, telling a friend 'I will continue eating this apple' using keizoku suru would sound very strange; you should use 'tabe-tsuzukeru' instead. Keizoku suru is best reserved for activities that have a certain weight or formal structure.

Mistake 1: Formality Mismatch

Using it for simple, everyday physical actions.
Incorrect: 'TV wo keizoku shite mimasu' (I will continue watching TV).
Correct: 'TV wo mi-tsuzukemasu.'

Another frequent error involves the misuse of particles. Because keizoku suru can be both transitive (taking an object) and intransitive (describing a state), learners sometimes mix up 'wo' and 'ga.' If you say 'benkyou ga keizoku suru,' it sounds like the studying is continuing by itself, which is logically odd in most cases. You should say 'benkyou wo keizoku suru' (I continue my studies). Conversely, for a natural phenomenon like rain, 'ame wo keizoku suru' would imply you are controlling the rain, which is impossible. Use 'ame ga keizoku suru' instead.

Mistake 2: Particle Confusion

Using 'wo' for natural states or 'ga' for intentional actions.
Incorrect: 'Keiyaku ga keizoku suru' (The contract continues - okay, but 'keiyaku wo keizoku suru' is better if you are the one renewing it).

A third mistake is confusing keizoku suru with iji suru (to maintain) or shinkou suru (to progress). While they are related, keizoku suru specifically refers to the temporal aspect—not stopping. Iji suru focuses on keeping the quality or level the same. If you are maintaining your weight, you use 'iji suru.' If you are continuing your diet, you use 'keizoku suru.' Mixing these up can lead to subtle misunderstandings about your goals or the status of a project.

Mistake 3: Semantic Overlap

Using 'keizoku' when 'iji' (maintenance) or 'renkyuu' (consecutive) is needed.
Incorrect: 'Kono ondo wo keizoku suru' (Continue this temperature).
Correct: 'Kono ondo wo iji suru' (Maintain this temperature).

Finally, be careful with the noun form. In English, we say 'continuation of...' but in Japanese, the word order is '...no keizoku.' Forgetting the 'no' particle or putting it in the wrong place is a common syntax error for beginners. Also, remember that 'keizoku' is a Sino-Japanese word, so it's usually written in Kanji. Writing it in Hiragana (けいぞく) is acceptable but might look childish in a professional email.

To truly master 継続する (keizoku suru), you must understand its position within a family of related verbs. Japanese has several ways to express the idea of 'continuing,' each with its own nuance and level of formality. The most direct alternative is the native verb tsuzukeru. While both can often be translated as 'to continue,' tsuzukeru is more versatile and can be attached to other verbs to form compounds, like 'yomi-tsuzukeru' (keep reading). Keizoku suru cannot be used this way; it stands alone as a suru-verb.

Keizoku suru vs. Tsuzukeru

Keizoku suru is formal, objective, and often refers to systems or long-term plans. Tsuzukeru is common, subjective, and used for any action, large or small.

Another similar word is 持続する (jizoku suru). While keizoku focuses on the act of not stopping, jizoku focuses on the 'duration' or 'sustainability' of a state. It is often used for things that have a natural tendency to fade, like the effects of medicine or the heat of a fire. In the context of the environment, 'sustainable development' is translated as 'jizoku kanou na kaihatsu.' If you want to emphasize that something lasts a long time, jizoku is often the better choice. Then there is 続行する (zokkō suru), which means 'to resume' or 'to carry on' after an interruption. If a game is paused and then starts again, you would use zokkō.

Comparison Table

Keizoku: Formal continuation of a process.
Jizoku: Duration/Sustaining a state over time.
Zokkō: Carrying on after a break or specifically in games/tasks.

For even more specific contexts, you might use 維持する (iji suru) for 'maintaining' a level, or 存続する (sonzoku suru) for 'surviving' or 'existing' (often used for companies or species). If a company is about to go bankrupt but manages to stay in business, it 'sonzoku's. Keizoku wouldn't be quite right there because sonzoku emphasizes the existence itself rather than just the activity. In academic writing, you might also see 継承する (keishō suru), which means 'to inherit' or 'to carry on a legacy.' This is specifically for traditions, skills, or titles passed from one person to another.

Summary of Nuances

Choose Sonzoku for survival, Keishō for legacy, and Iji for maintaining a specific standard.

In conclusion, while 'continue' is a broad word in English, Japanese breaks it down into several specific concepts. Keizoku suru is your go-to for the formal continuation of actions, projects, and habits. By comparing it with its synonyms, you can express yourself with much greater precision and sound more like a native speaker in professional environments.
