Meaning
The kanji 建 carries the core meaning of building, constructing, or establishing something — whether it's a physical structure like a house or tower, or an abstract institution like a nation or organization. When you see 建 in a word, think of the active process of bringing something into existence from the ground up.
Etymologically, 建 is a compound ideograph. The bottom component 廴 (えんにょう) represents a long, stretching stride — the idea of extending or moving forward across a distance. The upper-left component 聿 (ふでづくり) originally depicted a hand holding a writing brush, symbolizing purposeful action. Together, they suggest someone striding forward with intention — building something step by step, just as you would lay bricks one by one when constructing a wall.
This kanji has 9 strokes and is taught in Japanese elementary school Grade 4. Its radical is 廴, the "long stride" radical, which appears in only a small number of kanji, making 建 somewhat distinctive in shape. That sense of extending outward fits the idea of construction well — reaching into space to create something new.
In everyday life, you'll encounter 建 on construction site signs, real estate listings, architecture company names, and historical descriptions of when famous buildings or nations were founded. It shows up in both formal documents and casual conversation, making it one of the more useful N4 kanji to know early.
Readings
On'yomi (音読み) — Chinese-derived readings
The on'yomi readings of 建 are ケン and コン. These Chinese-derived readings appear primarily in compound words (熟語, jukugo), especially in formal, academic, or professional vocabulary.
ケン is by far the more common on'yomi. You'll hear it in architectural, civic, and political vocabulary:
- 建築 (kenchiku) — architecture, building construction
- 建設 (kensetsu) — construction, development
- 建国 (kenkoku) — founding of a nation
コン is less common and appears mainly in the word 建立 (konryū), which refers specifically to the erection of a temple, shrine, or Buddhist structure. This reading carries a classical, religious flavor and is rarely used outside of that context. You might see it on plaques at old shrines explaining when they were built.
- 建立 (konryū) — erection of a temple or shrine
Kun'yomi (訓読み) — Native Japanese readings
The kun'yomi readings are た.てる and た.つ. These native Japanese verb forms tend to sound more grounded and direct than their on'yomi equivalents — the kind of language you'd hear on a construction site rather than in an official report.
たてる is a transitive verb meaning "to build" or "to set up." You use it when someone actively builds or constructs something. The dot (.) in た.てる indicates the okurigana — the hiragana that follows the kanji when writing the full verb form 建てる.
- 家を建てる (ie wo tateru) — to build a house
- 建て直す (tatenaosu) — to rebuild, to reconstruct
- 建て物 (tatemono) — a building, a structure
たつ is the intransitive counterpart, meaning "to be built" or "to stand (of a building)." It describes a structure that has come to stand in place.
- 新しいビルが建った (atarashii biru ga tatta) — a new building was built / now stands

Memory Tip
Picture a construction worker striding across a muddy site, blueprint tucked under one arm, brick in hand. The bottom part of 建 — the radical 廴 — looks like a long sweeping footstep, someone marching forward. The upper portion resembles a hand gripping a tool. Put them together: a person moving with purpose, building as they go.
Whenever 建 comes up, call to mind that worker mid-stride, tool raised. You can also anchor it through the Hán-Việt reading: KIẾN — as in kiến trúc (architecture) or kiến thiết (construction) in Vietnamese, both sharing the same root. For Vietnamese learners especially, that connection makes 建 click almost immediately.
