一年間(いちねんかん)

いちねんかん
noun
one year; for one year; period of one year
1. one year; period of one year
A duration of one year. The 間(かん) suffix emphasizes a continuous span of time, distinguishing this from 一年(いちねん), which can also mean 'first year.'
一年間(いちねんかん)日本(にほん)に住(す)んだ。
I lived in Japan for one year.
一年間(いちねんかん)の留学(りゅうがく)経験(けいけん)がある。

この保険(ほけん)は一年間(いちねんかん)有効(ゆうこう)で、毎年(まいとし)更新(こうしん)する必要(ひつよう)がある。
This insurance is valid for one year and must be renewed annually.

Adds the duration suffix 間(かん) to 一年(いちねん), making the meaning unambiguously 'for one year' rather than 'first year.'

  • 一年間(いちねんかん)続(つづ)く: to continue for one year
  • 一年間(いちねんかん)の予定(よてい): a one-year plan
  • 一年間(いちねんかん)有効(ゆうこう): valid for one year
