起きる
おきる
okiru
= to wake up; to get up; also: to occur
起きる (okiru) is one of those verbs that pulls double duty in Japanese: it describes the very personal act of waking from sleep, and it also captures the impersonal moment when events unfold in the world. Mastering both senses — and knowing when to reach for 起こる or 起こす instead — is a key milestone for N5 learners.
起きる is an ichidan (ru-verb) intransitive verb with two closely related but distinct meanings.
① To wake up / to get up — describing the act of rousing oneself from sleep or rising from a lying position. The subject is always the person who wakes themselves: “毎朝6時に起きる” (I wake up at 6 every morning). Because it is intransitive, you cannot use 起きる to say you woke someone else up — for that, the transitive 起こす (okosu) is required.
② To occur / to happen — describing events, incidents, or situations that arise. Here 起きる overlaps with 起こる (okoru), and both are acceptable in many contexts: “事故が起きた” and “事故が起こった” are interchangeable in everyday speech. However, 起きる in this sense carries a slight nuance of unexpectedness or urgency, making it especially common in news headlines and spoken alerts.
Conjugation follows the standard ru-verb pattern: 起きます (polite), 起きない (negative), 起きた (past), 起きている (ongoing state — still awake / currently happening).
The trio 起きる / 起こる / 起こす trips up many learners. Remember: 起きる and 起こる are both intransitive (no direct object), but 起きる is used for people waking themselves as well as events, while 起こる focuses almost exclusively on events. 起こす is transitive — it needs an object: “弟を起こした” (I woke my younger brother up). A quick test: if you can insert “〜を” before the verb, you want 起こす; otherwise choose 起きる or 起こる.
Another common mistake is confusing 起きれる and 起きられる. In casual speech 起きれる (ra-dropped) is widespread, but in formal writing 起きられる is the correct potential form: “明日、6時に起きられますか？”
起 is composed of 走 (hashiru, to run/dash) on the left and 己 (onore, self/oneself) on the right. The combined image is of the self propelling forward from rest into motion — a body springing up and dashing ahead. This etymology neatly captures both meanings of 起きる: the physical act of rising from bed and the sudden onset of an event breaking into motion.
Everyday use
今日は7時に起きたから、電車に間に合った。

Casual / Social Media
また起きれなかった〜😭 寝坊して遅刻確定です。

Formal / Cultural context
緊急事態が起きた場合は、速やかに担当者までご連絡ください。
Kinkyuu jitai ga okita baai wa, sumiyaka ni tantousha made go-renraku kudasai.
If an emergency occurs, please contact the person in charge immediately.
Japan has a deep cultural appreciation for early rising captured in the proverb 早起きは三文の徳 (hayaoki wa sanmon no toku) — literally ‘rising early is worth three mon (coins),’ equivalent to ‘the early bird catches the worm.’ This value is baked into school schedules, corporate culture, and the wildly popular genre of morning information programs (朝の情報番組) that air from around 5:30 a.m. and attract millions of viewers who are already up, dressed, and eating breakfast before 7.
The second meaning of 起きる — events occurring — takes on particular weight in Japanese news and disaster communication. Because Japan lies on the Pacific Ring of Fire, phrases like 「地震が起きた」 (an earthquake occurred) and 「津波が起きる恐れがある」 (there is a risk of a tsunami occurring) are part of the everyday emergency vocabulary that Japanese residents encounter through public alert systems and broadcast announcements. This dual nature of 起きる — mundane mornings and sudden emergencies — reflects the word’s role at the very heart of daily Japanese life.
