〜一方で

on the other hand / while

N2conjunctions

〜一方で is a conjunction meaning on the other hand / while, used to connect clauses and express logical relationships between ideas. Japanese has a rich set of conjunctions that convey subtle differences in meaning — contrast, cause, concession, addition — and using them correctly makes your Japanese flow naturally.

This is an advanced pattern found primarily in formal writing, news articles, business Japanese, and academic texts.

Common Mistakes#

  1. Using 〜一方で interchangeably with 〜かたがた / 〜かたわら — These patterns are similar but not identical. 〜かたがた / 〜かたわら (while also / besides) may be preferred in different contexts or registers.
  2. Using 〜一方で in casual conversation — This pattern sounds overly formal or literary in casual speech. Reserve it for formal writing, presentations, or situations that call for elevated language.
  3. Direct translation from English — The concept expressed by 〜一方で may not map one-to-one with its English translation. Focus on understanding the Japanese usage through example sentences rather than relying on the English gloss.
