The Kanji: 木 (Ki/Moku) - The "Tree" and "Wood" Kanji
The kanji 木 is a foundational character that directly represents a "tree" or "wood." It is one of the most basic and visually intuitive kanji, serving as a building block for many other characters.

2. Writing and Stroke Order: The Shape of a Tree
The correct kanji writing for "木" is simple but fundamental. Its stroke order is logical and forms the basis for more complex characters.
Stroke Order:
Stroke 1: A long horizontal stroke from left to right. This represents the branches of the tree.
Stroke 2: A long vertical stroke that starts above the horizontal stroke, cuts through it, and extends below it. This represents the trunk of the tree.
Stroke 3: A left-falling stroke attached to the vertical trunk, sweeping down to the left. This represents the roots on the left side.
Stroke 4: A right-falling stroke attached to the vertical trunk, sweeping down to the right. This represents the roots on the right side.
Significance of Correct Kanji Writing:
Visual Representation: The character is a perfect abstract diagram of a tree: a horizontal line for branches, a vertical line for the trunk, and two diagonal lines for roots. This is a prime example of how correct kanji writing visually conveys meaning.
Balance and Proportion: The horizontal stroke should be centered on the vertical. The two root strokes should be symmetrical, creating a stable, balanced character.
Foundation for Other Kanji: "木" is the "tree" radical (きへん, kihen). When it appears as a component in other kanji, it often relates to trees, wood, or things made from wood (e.g., 林 - woods, 森 - forest, 机 - desk, 板 - board). Mastering its stroke order here is essential for writing those characters correctly.
3. Historical Origin and Evolution
The history of "木" is a clear and straightforward evolution from a pictogram to a stylized symbol.
Oracle Bone Script (甲骨文字):
The earliest form was a simple and elegant pictogram of a tree. It clearly showed a tree with roots spreading underground on the bottom and branches extending upward on the top. The central line represented the trunk.
Bronze Script (金文) & Seal Script (篆書):
The form became slightly more stylized. The roots and branches were often represented by curved, graceful lines, but the overall shape of a tree with a central trunk was completely unmistakable.
Modern Form (楷書):
The modern "木" is a clean and minimalist abstraction of its ancient form. The curved lines have been straightened into the four strokes we use today, but the symbolic representation remains perfectly intact: the horizontal line (branches), the vertical line (trunk), and the two diagonal lines (roots).
Cultural and Philosophical Connection:
In Japanese culture and East Asian philosophy, "木" is one of the Five Elements (五行, gogyō: 木, 火, 土, 金, 水 - Wood, Fire, Earth, Metal, Water). In this system, Wood represents:
Growth, Vitality, and Expansion: Like a tree growing upward and outward.
Springtime: The season of new life and growth.
The Color Green and The East Direction
This is why Thursday is 木曜日 (Day of Wood), following the planetary association system. The character embodies the energy of life, nature, and upward growth.
Summary
The kanji 木 is a perfect starting point for understanding the logic and beauty of the Japanese writing system. It began as a literal drawing of a tree and evolved into a simple, symbolic character. Mastering its stroke order is one of the first and most important steps in Japanese kanji writing, as it teaches the fundamental principles of balance and visual meaning. When you learn how to write kanji like "木," you are not just learning a word for "tree"; you are learning a radical that forms the root of countless other characters and a symbol that represents the vibrant, growing energy of nature itself.
