while; at the same time; in addition
Expresses doing something alongside another main activity, often with a sense of balance or dual commitment.
This pattern indicates that someone does something in addition to their main activity, often implying a long-term or habitual secondary pursuit. It is similar to 'while doing' but carries a nuance of parallel dedication. For example, a person might work at a company while also studying for a degree. The main activity is usually the primary focus, and the secondary one is done alongside it. It is formal and primarily used in written Japanese, such as articles, reports, or formal speeches. In conversation, you would more likely use ながら or 一方で.
