📖 How to use it

Indicates that an action or state is currently in progress or ongoing throughout a period.

Attaches to For 'chuu' (currently/during), attach to the ます-stem of a verb (e.g., 仕事中) or to a noun indicating an activity (e.g., 会議中). For 'juu' (throughout), attach to a noun indicating a period or place (e.g., 一日中, 世界中).

The suffix 中 has two readings with different meanings. When read as 'chuu', it means 'in the middle of' or 'during', and it attaches to the stem of a verb (the form before ます) or to a noun that represents an activity. For example, 仕事中 means 'in the middle of work', and 会議中 means 'during the meeting'. This is common in everyday speech to describe what someone is currently doing, often as a status update or a polite way to say someone is busy. When read as 'juu', it means 'throughout' or 'all over', and it attaches to nouns that represent a period or a place, like 一日中 (all day) or 世界中 (all over the world). This reading emphasizes the entirety of the time or space. You can remember the difference: 'chuu' is like being in the middle of something, while 'juu' covers the whole thing.

すみません、今、電話中です。
Sumimasen, ima, denwa-chuu desu.
Sorry, I'm on the phone right now.
会議中は、スマホを消してください。
Kaigi-chuu wa, sumaho o keshite kudasai.
Please turn off your smartphone during the meeting.
彼は一日中図書館で勉強していた。
Kare wa ichinichijuu toshokan de benkyou shite ita.
He was studying at the library all day.
Not 最中 (saichuu) 最中 also means 'in the middle of' but emphasizes that something is happening at that exact moment and often implies interruption. For example, 食事の最中に電話が鳴った (the phone rang in the middle of eating). 中 (chuu) is more general and can be used for status like 仕事中.
Register This pattern is used in both spoken and written Japanese, but the 'chuu' reading is common in polite speech and business contexts, while 'juu' is neutral and used in everyday conversation.
