夏休み
なつやすみ
natsuyasumi
= summer vacation; summer break
In Japan, 夏休み (natsuyasumi) is more than just time off school — it arrives every late July packed with mandatory homework, early-morning radio exercises, and the distant sound of festival drums. No other season carries this same dense ritual calendar.
夏休み refers specifically to the summer recess observed by schools, typically running from late July to late August (roughly 40 days). Students return to a stack of required assignments rather than an empty schedule.
In a workplace context, the equivalent break is called 夏季休暇 (kakki kyūka) or colloquially 盆休み (bon yasumi), centered on the Obon week in mid-August. Using 夏休み in a business email to describe your company’s closure can sound slightly childlike; 夏季休暇 is the professional register.
Three terms overlap in meaning but belong to different contexts:
• 夏休み — school summer break; also the default casual word children and students use
• 夏季休暇 (kakki kyūka) — the formal, business-register equivalent; appears in company announcements and official correspondence
• 盆休み (bon yasumi) — informal term for the Obon holiday cluster (around August 13–16); used in casual adult speech when referring specifically to that mid-August period
A common learner mistake is using 夏休み in a work email. Swap it for 夏季休暇 whenever you write to a client or manager.
夏休み is written with two kanji components: 夏 (natsu), meaning summer, and 休 (yasu), meaning rest or pause — the same character found in 休日 (holiday) and 休憩 (break). The み ending nominalizes the verb 休む (yasumu, to rest), making 休み a noun meaning “a rest period.” Together, 夏休み literally means “the summer’s resting time.”
Everyday use
夏休みの計画、もう立てた？家族でどこか行くの？
Natsuyasumi no keikaku, mō tateta? Kazoku de doko ka iku no?
Have you made plans for summer break yet? Are you going somewhere with your family?
Casual / Social Media
夏休みは沖縄に行ってきた！海が最高だったよ。
Natsuyasumi wa Okinawa ni itte kita! Umi ga saikō datta yo.
I went to Okinawa for summer break! The ocean was amazing.
Formal / Cultural context
弊社の夏季休暇は8月13日から16日までとなっております。
Heisha no kakki kyūka wa hachi-gatsu jūsan-nichi kara jūroku-nichi made to natte orimasu.
Our company’s summer holiday period runs from August 13th through the 16th.
Japanese summer homework (夏休みの宿題) is a defining feature of 夏休み that surprises many non-Japanese learners. Students receive an assignment packet on the last school day — typically including a reading report (読書感想文), an independent research project (自由研究), a daily illustrated diary (絵日記), and math drills. The sheer volume is calculated to fill the entire break, and submitting unfinished work on the first day back is a social embarrassment every Japanese adult remembers vividly.
Another institution unique to 夏休み is ラジオ体操 (rajio taisō) — a standardized calisthenics routine broadcast on NHK Radio at 6:30 a.m. every morning throughout the break. Children gather at neighborhood parks, stamp an attendance card for each session, and earn a small prize for completing all sessions. The melody is so recognizable that hearing it as an adult can instantly recreate the feeling of a humid August dawn. This ritual has run virtually unchanged since 1928 and remains one of the most culturally loaded sounds of a Japanese summer.
