  • 一瞬 (isshun): an instant.

  • 一石二鳥 (isseki nichō): 'kill two birds with one stone.'

Philosophical Symbolism

In Zen Buddhism, 一 (ichi) represents the oneness of reality (一如 – ichinyo): the idea that all phenomena are interconnected. It symbolizes beginning, unity, and the source of all multiplicity. A Zen phrase states: 'From one, ten thousand things arise.' Thus, 一 (ichi) carries profound weight beyond its numerical value.

Radical and Structural Role

As a radical, 一 (ichi) is the simplest of all. It often appears as a component to suggest unity or the number one. For example:

  • 三 (san) literally builds on 一 (ichi) by adding more strokes.
  • 百 (hyaku) contains 一 (ichi) at the top, symbolizing the unit that structures larger numbers. Thus, 一 (ichi) is both a number and a structural building block in the kanji system.
