The character 震 evolved from ancient oracle bone script depicting thunder and rain, combining the radical 雨 (rain) with 辰 (which originally represented a clam shell used in farming and later came to signify time or stars). The character fundamentally means 'to shake' or 'to quake,' as in earthquake (地震) or thunder (震雷), but also carries meanings of awe and terror inspired by powerful natural phenomena. Over centuries, the character simplified while maintaining its core elements - the rain radical above representing heavenly forces, and the 辰 component below suggesting the vibrational impact on earthly matters. Arrived in Japan: The character 震 likely arrived in Japan during the 5th-6th centuries CE along with the broader introduction of Chinese writing systems, possibly through Buddhist texts and diplomatic exchanges. It became firmly established in the Japanese writing system by the Nara period (710-794 CE) and appears in early Japanese dictionaries and literary works, retaining its meanings related to shaking, quaking, and thunder.
