  • Synonym活用かつようNeutralMaking full or flexible use of something, as in 「経験を活用する」; the emphasis is on using it well. In grammar it also means conjugation.
  • Synonym使うつかうNeutralThe everyday verb for using something, as in 「箸を使う」; the most common word in speech. 「使用」 is a Sino-Japanese noun with a more formal feel.
  • Synonym用いるもちいるWrittenA written-style verb meaning to use or adopt, as in 「新しい方法を用いる」; it can also mean employing a person. More formal than 「使う」.
  • Synonym役立てるやくだてるNeutralPutting something to use so it helps, as in 「経験を仕事に役立てる」; the focus is on the benefit gained, which 「使用」 does not imply.
  • Synonym行使こうしFormalFormal word for exercising rights, power or force, as in 「武力行使」 and 「権利を行使する」; 「使用」 refers broadly to using things.

  • Related適用てきようNeutralApplying a rule, law or method to a specific case, as in 「保険が適用される」; 「使用」 just means using something in general.
  • Related当てはめるあてはめるNeutralApplying or fitting a rule or formula onto something; close to 「適用」 but more colloquial. 「使用」 is general use with no such nuance.
  • Related応用おうようNeutralPutting theory or knowledge to practical use, as in 「応用問題」; the idea is adapting what you know, while 「使用」 is simply using a thing.
  • Antonym不使用ふしようWrittenA written-style word meaning not using or having stopped using something; it directly negates 「使用」 and appears often in manuals and rules.

Default to 「使用」 for the neutral act of using something, especially in writing or formal speech; in everyday talk say 「使う」. Use 「利用」 for benefiting from something, 「活用」 for putting it to good use, 「適用」 for applying rules, and 「行使」 for rights or power.
