Explore each form from the oldest known stage to today.
The character 基 evolved from ancient pictographs representing a foundation or base. In oracle bone script, it depicted earth (土) as the fundamental element, combined with other elements indicating measurement or establishment. Over time, it standardized to its current form with 其 (originally a basket pattern) above 土 (earth), symbolizing 'building upon the earth' - the very concept of foundation. The character carries meanings of foundation, basis, fundamental, and radical, reflecting its core concept of something that serves as the starting point or support for everything else. Arrived in Japan: The character 基 likely arrived in Japan during the 5th-6th centuries CE along with the broader introduction of Chinese writing systems, either directly from China or via the Korean peninsula. It was incorporated into the Japanese writing system as a kanji during the Asuka period when Buddhist texts and Chinese classics were being transmitted to Japan.
