きかんちゅう
noun
during the period; throughout the period
time-general
1. during the period; throughout the period; while the specified period is ongoing
Specifies a time frame that begins and ends with a particular period — typically a sale, campaign, exhibition, event, or contract term. Functions both as a noun and, very commonly, as an adverbial modifier placed at the start of a sentence.

There are discounts during the sale period.
期間中(きかんちゅう)はいつでも返品(へんぴん)できます。

Customers who purchase a product during the campaign period will receive a special gift.

Compound of 期間(きかん) ('period; term') and the suffix 〜中(ちゅう) ('during; in the middle of'). Structurally a noun, but overwhelmingly used adverbially, often at the head of a sentence, to specify the duration in which something applies.

Usage

  • Frequently preceded by a specific period noun: セール期間中(きかんちゅう), キャンペーン期間中(きかんちゅう), 開催(かいさい)期間中(きかんちゅう).
  • Alone, refers back to a period established by context.
  • Very common in advertisements, event announcements, travel notices, contracts, and official bulletins.

Common collocations

Similar words

  • 期間内(きかんない): within the period — more formal and contractual, emphasizing that something must fall inside the set period (e.g., 期間内(きかんない)の返品(へんぴん), 'returns made within the period').
  • 〜中(ちゅう): during — the bare suffix, used productively with many nouns (e.g., 会議中(かいぎちゅう), 'during the meeting').
  • 最中(さいちゅう): right in the middle of — emphasizes being actively in progress, often with vivid, moment-by-moment nuance.
