Meaning
The N3 kanji 必 (ひつ, かなら-ず) conveys a strong sense of "must," "certainly," or "without fail." It's a character you'll frequently encounter when expressing necessity, inevitability, or an absolute requirement. You can think of it as a firm declaration: something will, or should, happen with no room for doubt. This kanji is all about certainty and compulsion, indicating an unavoidable or essential action or outcome.
This section explores the interesting origins of 必. While it's not a simple pictograph of an object, 必 is considered an ideograph that conveys an abstract concept. One common theory suggests it depicts a heart (心, which forms the lower part of 必) with something piercing it from above. This imagery evokes a sense of being "fixed" or "certain." Just as a pierced object is held firmly in place, an event described with 必 is certain to occur.
Another theory links it to an arrow hitting a target, implying "accuracy" or "without fail." The top stroke that crosses over the 'heart' radical reinforces this sense of a definitive action or mark. It ensures a target is met or a condition is fulfilled.
Visually, you can clearly see the radical 心 (kokoro, heart) at the bottom. The top part, which resembles the kanji 八 (hachi, eight) or a simplified arrow/cross, signifies a fixed point, a boundary, or an inescapable condition. This combination strongly reinforces the idea of something definite, absolute, and unavoidable. So, when you encounter 必, remember that it always signals something definite, required, or certain.
This kanji has 5 strokes and is taught in Grade 4 in Japanese schools, making it a relatively early character to learn in your kanji journey.
Readings
The kanji 必 has both on'yomi (Chinese-derived) and kun'yomi (native Japanese) readings. Understanding both is key to mastering 必 and knowing when to apply them correctly in Japanese vocabulary.
On'yomi (音読み) — Chinese-derived readings
The primary on'yomi reading for 必 is ヒツ (Hitsu). This reading typically appears in compound words, especially those relating to necessity, certainty, or requirements. These are often derived from Chinese vocabulary, giving them a more formal or technical feel.
- 必要 (hitsuyō) — meaning "necessity," "essential," or "required." This is one of the most frequently encountered words using 必 and is fundamental to daily communication. For example: 「これは生活に必要なものです。」 (Kore wa seikatsu ni hitsuyō na mono desu.) - "This is something essential for life."
- 必須 (hissu) — meaning "indispensable," "essential," or "compulsory." While similar to 必要, 必須 often implies a stronger, more non-negotiable requirement. For example: 「大学の卒業には必須科目を修める必要があります。」 (Daigaku no sotsugyō ni wa hissu kamoku wo osameru hitsuyō ga arimasu.) - "Completing indispensable subjects is necessary for university graduation."
- 必然 (hitsuzen) — meaning "inevitability," "necessity," or "destiny." This word describes something that is bound to happen or is logically unavoidable. For example: 「その結果は必然だった。」 (Sono kekka wa hitsuzen datta.) - "That outcome was inevitable."
Kun'yomi (訓読み) — Native Japanese readings
The main kun'yomi reading for 必 is かなら-ず (kanarazu). This reading functions as an adverb, meaning "certainly," "without fail," or "must." It often appears on its own or with hiragana attached, giving a distinctly Japanese feel to the expression of certainty.
- 必ず (kanarazu) — This is the most common form of the kun'yomi, acting as an adverb to emphasize certainty. It's used for strong promises, commands, or predictions. For example: 「明日は必ず来てください。」 (Ashita wa kanarazu kite kudasai.) - "Please come tomorrow without fail." It conveys a strong sense of obligation or assurance.
- 必ずしも (kanarazushimo) — This is a crucial expression that, when followed by a negative verb, means "not necessarily." It's used to express that something is not always the case or is not absolutely required. This phrase is vital for expressing nuanced opinions. For example: 「お金持ちが必ずしも幸せとは限らない。」 (Okanemochi ga kanarazushimo shiawase to wa kagiranai.) - "It's not necessarily true that wealthy people are happy."

Memory Tip
To remember 必, visualize a "heart" (心) that is "certainly" fixed or "must" follow a particular direction. Imagine an arrow (the upper part resembling a simplified arrow or a cross mark) piercing a heart, making it certain to feel something, or that it must react in a particular way. Another useful image is a heart (心) with a firm "lid" or "cover" (the top part) on it, symbolizing that its fate is sealed—it must be. These visuals of something being firmly held, marked, or contained help solidify the idea of "certainty" or "necessity." Keep this phrase in mind: "The heart must be certain!"
