as; due to; with; along with; following
Expresses that one change or event happens together with, or as a result of, another change or event.
This pattern is used when two things occur in parallel, often with a cause-effect or correlation. It is common in formal speeches, news reports, and written explanations. It is not used in casual conversation; in speech you would use にしたがって or とともに, or simpler structures like 〜につれて (for verbs) or 〜で (reason).
The nuance is that the second clause is a natural or inevitable result of the first. For example, as the economy grows, people's lives improve. The subject is often impersonal or abstract, such as society, technology, or the times.
