What It Means
発展をする is all about progress and growth. It describes a transition from a simple state to a complex one. Think of it as 'leveling up' in real life. It’s not just about getting bigger. It’s about becoming better, more refined, or more influential. You’ll see this used for economies, technologies, and even relationships.
How To Use It
Grammatically, this is a noun 発展 combined with the verb する. Adding the particle を makes the action feel a bit more deliberate. You usually pair it with a subject that is capable of change. For example, 経済が発展をする (the economy develops). You can also use it transitively as 発展させる to mean 'to develop something.' It's a very flexible and positive-sounding phrase.
When To Use It
Use this when you want to sound professional or observant. It’s perfect for business meetings or writing reports. You can also use it when discussing history or urban planning. If you're talking about how your favorite anime series has grown in complexity, this works too! It carries a sense of forward momentum that people find very inspiring.
When NOT To Use It
Don't use this for biological growth. If your nephew grew five inches, use 成長する instead. 発展をする is for systems, organizations, or abstract concepts. Also, avoid using it for things that are getting worse. You wouldn't say a disease 'develops' with this word unless you're being very clinical or ironic. It almost always implies a 'good' kind of progress.
Cultural Background
In Japan, the word 発展 carries a lot of weight. After World War II, the 'Economic Miracle' was described as a period of rapid 発展. Because of this, the word is deeply tied to national pride and hard work. When a Japanese person hears this word, they often think of skyscrapers and high-speed trains. It represents the collective dream of a better future.
Common Variations
In casual speech, people usually drop the を and just say 発展する. If you want to say something is 'developing' right now, use 発展している. If you want to describe a 'developing country,' the term is 発展途上国. You might also hear 大発展, which means a 'huge' or 'great' development. It’s a great way to add some drama to your progress report!
Notas de uso
This phrase is neutral but leans towards formal contexts. In casual speech, the `を` is almost always omitted to form `発展する`.
The 'O' Factor
Including the `を` makes the sentence feel more 'written' or 'prepared.' In quick conversation, you'll almost always hear just `発展する`.
Not for Plants!
Never use this for flowers or trees. If it's alive and growing physically, use `生長` (seichou) or `育つ` (sodatsu).
The Ultimate Compliment
In business emails, saying `貴社の益々のご発展をお祈り申し上げます` is the gold standard for wishing a company continued success.
