毎日
まいにち
mainichi
= every day; daily
毎日 (mainichi) is one of the first time words Japanese learners encounter — and for good reason. Whether you’re talking about a morning commute, a language study habit, or a fitness routine, this single word anchors the rhythm of daily life in Japanese conversation.
毎日 means “every day” or “daily” and functions both as an adverb modifying a verb and as a noun referring to the concept of each day. As an adverb, it typically appears before the verb or at the start of a sentence to set the time frame: 毎日学校に行きます (I go to school every day). As a noun, it can be the subject or topic of a sentence: 毎日が楽しいです (Every day is fun). Unlike 日々 (hibi), which carries a more literary or reflective tone, 毎日 is the natural, neutral choice for casual and formal speech alike. It emphasizes consistent repetition — the fact that something happens on each and every day without exception.
A common point of confusion for English speakers is the proper position of 毎日 in a sentence. Japanese follows a time-before-verb order, so 毎日 comes near the beginning of the clause, not at the end as English “every day” often does. Say 毎日日本語を勉強しています, not ×日本語を勉強しています毎日. Another source of confusion is the proper noun 毎日新聞 (Mainichi Shimbun), one of Japan’s major national newspapers. The pronunciation is identical to the common word, so context makes the difference — the newspaper is almost always referred to with 新聞 attached. Finally, note the handy expression 毎日のように (mainichi no you ni), meaning “almost every day” or “as if every day” — useful when you want to convey high frequency without claiming absolute daily occurrence.
毎日 is built from two kanji with transparent meanings. 毎 (mai) is a prefix meaning “every” or “each” and appears in a productive series of time words: 毎週 (maishuu, every week), 毎月 (maitsuki, every month), 毎年 (maitoshi/mainnen, every year), and 毎朝 (maiasa, every morning). The character 毎 depicts a woman with an ornamental hairpin, historically associated with regularity and nurturing routine. 日 (nichi/hi) means “day” or “sun” and is one of the most common kanji in everyday Japanese. Together, 毎日 literally reads as “each day,” making its meaning immediately deducible once you recognize the 毎〜 pattern.
Everyday use
彼女は毎日30分ジョギングをしています。
Kanojo wa mainichi sanjuppun jogingu wo shite imasu.
She goes jogging for 30 minutes every day.
Casual / Social Media
毎日コーヒーを飲みながら日本語の単語を覚えています。
Mainichi koohii wo nominagara nihongo no tango wo oboete imasu.
I memorize Japanese vocabulary every day while drinking coffee.
Formal / Cultural context
社員一同、毎日安全に業務を遂行するよう努めております。
Shain ichidou, mainichi anzen ni gyoumu wo suikou suru you tsutomete orimasu.
All employees strive to carry out their duties safely every day.
In Japanese work culture, 毎日 carries a quiet weight. The expectation of showing up and contributing 毎日 — reliably, without exception — is deeply embedded in professional norms. Phrases like 毎日お疲れさまです (Thank you for your hard work every day) are used by managers to acknowledge the sustained effort that daily presence represents, not just a single task completed.
For Japanese language learners abroad, 毎日 often becomes a personal mantra. Study communities and language-exchange apps frequently feature goals framed around 毎日: 毎日10分でも練習しよう (Let’s practice even just 10 minutes every day). This reflects a broader Japanese cultural value — 継続は力なり (keizoku wa chikara nari, persistence is power) — that prizes consistent daily effort over occasional bursts of intensity.
