Pronunciation /dʑɯ.kɯ/

Meaning

An after-school tutoring academy or cram school where students study supplementary lessons outside regular school.

塾 is a fundamental part of Japanese student life. Most students attend 塾 from elementary or middle school to supplement regular schoolwork and prepare for entrance exams. Unlike 予備校, 塾 serves a broader age range and covers both exam prep and general academic support. Japan has tens of thousands of 塾 ranging from small neighborhood operations to massive franchises like 公文 (Kumon).

Examples

  1. 小学校から塾に通ってたから遊ぶ時間なかったな。 I've been going to cram school since elementary, so I never had time to play.
  2. 塾の宿題と学校の宿題で毎日寝る時間ないんだけど。 Between cram school homework and regular school homework, I have zero time to sleep.
  3. 塾の先生のおかげで数学が好きになった。 Thanks to my cram school teacher, I actually started liking math.
