Meaning
The kanji 株 (kabu) has several core meanings, primarily 'stock' or 'share' in finance, and 'stump,' 'root,' or 'plant' in botany. At its core, 株 refers to a fundamental part or unit, whether it's the base of a tree or a unit of ownership in a company.
Its origin lies in a phono-semantic compound. The left radical, 木 (ki), explicitly means 'tree' or 'wood,' providing the semantic hint for its connection to plants and forestry. The right component, 朱 (shu), originally referred to 'vermillion' or 'cinnabar,' a red pigment. While its primary role in 株 is phonetic, 朱's underlying sense of 'base' or 'foundation' might have subtly influenced the kanji's meaning, evolving from a tree stump to a fundamental unit of ownership in a business.
The most ancient and literal meaning of 株 is a 'tree stump' – the remaining base of a tree after it has been cut down. Visually, the truncated tree (木) represents a solid, foundational base, directly connecting to the concept of a 'stump.' From this physical base, the meaning extended to the 'root' or 'origin' of a plant, and by extension, a single 'plant' or 'clump of plants.'
Through a metaphorical leap, this idea of a fundamental, indivisible unit then evolved. It came to mean a 'share' or 'stock' in a company, representing a portion of its foundational assets or ownership. This duality makes 株 a unique kanji, bridging the natural world with modern commerce.
The kanji 株 consists of 10 strokes and is a Jōyō Kanji. It is typically learned in secondary school (equivalent to Grade 8 or beyond in the Japanese education system), aligning with its N1 JLPT level classification.
Readings
On'yomi (音読み) — Chinese-derived readings
While some older dictionaries may list a rare on'yomi of コウ (KŌ) for 株, N1 learners should note that this reading is virtually unused in contemporary Japanese for any of its common meanings (stock, share, stump). In contemporary contexts, especially in business and everyday language, 株 is almost exclusively read with its kun'yomi. For practical purposes, therefore, learners should focus solely on this reading.
Kun'yomi (訓読み) — Native Japanese readings
The primary and almost exclusively used reading for 株 is its kun'yomi, かぶ (kabu). This reading covers all the main meanings associated with the kanji, from financial stocks to botanical stumps and plants.
- 株 (kabu) — This is the standalone reading for 'stock, share' (financial) or 'stump, root' (botanical). It's frequently encountered in both contexts.
Example: 彼は株で利益を上げた。(Kare wa kabu de rieki o ageta.) — He made a profit from stocks.
- 株式 (kabushiki) — This compound specifically refers to 'stock' or 'shares,' often seen in company names like 株式会社 (kabushiki gaisha), meaning 'stock company' or 'corporation.'
Example: 新しい株式が市場に公開された。(Atarashii kabushiki ga shijō ni kōkai sareta.) — New shares were released on the market.
- 切り株 (kirikabu) — This compound specifically means 'tree stump,' emphasizing the cut nature of the plant base.
Example: 森の中に古い切り株が残っていた。(Mori no naka ni furui kirikabu ga nokotteita.) — An old tree stump remained in the forest.

Memory Tip
To remember 株, visualize its components: 木 (tree) on the left and 朱 (scarlet) on the right. While 朱 primarily functions as a phonetic component, you can mentally associate its 'base' color with a foundation. Imagine a magnificent tree (木) that has been cut down, leaving only its fundamental, 'base' part behind – a stump (株). The 'stump' is the 'root' or 'foundation' of the tree, much like a 'share' is the fundamental 'unit' or 'foundation' of ownership in a company. Think of the deep red (朱) color sometimes seen in the fresh cut of a tree trunk, reinforcing the idea of a solid, rooted base. This visual helps link the natural 'stump' meaning to the abstract 'share' meaning, as both represent a foundational or fundamental portion of something larger.
