Origin
This is the simplest kanji — just a single horizontal line. It's a pictographic character that represents the number one by showing one stroke, the most basic mark you can make. The single line is literally a picture of the concept "one" in its most reduced form. Because of its extreme simplicity and fundamental meaning, it became the first radical (a building block used to organize other kanji) in Japanese dictionaries.
