Meaning
The kanji 秘 (ひ) primarily conveys the meanings of “secret,” “mystery,” “private,” “concealed,” and “profound.” It refers to anything kept hidden from others, not widely known, or possessing a deep, often mystical quality. This kanji is essential for expressing concepts like confidentiality, hidden knowledge, and enigmatic phenomena in Japanese.
Its origin lies in a fascinating combination of components. 秘 is a 形声文字 (keisei moji), a phono-semantic character, which means it combines a semantic component with a phonetic one. The left radical is 禾 (nogihen), commonly representing grain or crops. In this context, 禾 can symbolize something valuable, precious, or sacred.
The right component is 必 (hitsu), meaning “surely,” “must,” or “certainly.” The combination of these components suggests something precious or sacred (禾) that must (必) be kept hidden or secret. Furthermore, the phonetic component 必 is what gives rise to the On'yomi sound ヒ (Hi).
Thus, the visual form of 秘 effectively encapsulates the idea of something profoundly important that is intentionally kept from public view, much like a precious harvest carefully stored away for safety and privacy. This kanji has 10 strokes and is designated as a Jouyou Kanji (常用漢字) at the secondary school level (Grade S). It is an important character in everyday Japanese, though it is not taught in elementary school grades.

Memory Tip
To remember 秘, break it down into its components: 禾 (nogihen), representing "grain" or something valuable/sacred, and 必 (hitsu), meaning "certainly" or "must." Imagine a farmer who has just harvested a particularly precious and sacred grain (禾). They must (必) keep this special grain a secret, carefully hiding it away to protect its profound value. This creates the image of the "certainly hidden grain," or something that "must be kept secret." This visual mnemonic helps connect the idea of something important that is intentionally concealed or held in profound secrecy.
