The Japanese word 箱 (箱, reading: はこ, *hako*) primarily means "box" or "container." It refers to an object with a lid or sides used for storing or carrying things. It can be of various shapes, sizes, and materials, from a simple cardboard 箱 to an elaborate wooden 箱. The meaning extends to include any container used for holding items.

You use 箱 in any context where you're referring to a 箱 or container. It's a common word, and the specific context of the conversation clarifies what kind of 箱 is being discussed. It's often used with other words to provide more detail, such as the material (e.g., 木箱 - wooden box), the contents (e.g., 宝石箱 - jewelry box), or the size (e.g., 大きな箱 - big box).

The word 箱 is most commonly written with the kanji 箱. However, when you're just starting to learn Japanese, it is written in hiragana はこ. The okurigana (the suffix hiragana) does not change, as the word itself does not conjugate.

There are some words that can have a similar meaning depending on the context. ⚫︎ 容器 (ようき, *youki*) - container ⚫︎ ケース (*keesu*) - case ⚫︎ 入れ物 (いれもの, *iremono*) - container, receptacle

There are no direct antonyms for 箱, as it is a noun that describes an object. However, you could consider the opposite of "being contained" which would be "not being contained", such as ⚫︎ 外 (そと, *soto*) - outside
