Yotsu-bishi— Japanese Family Crest (Kamon)

Yotsu-bish(Four-Diamonds Crest) （Kamon)

Overview

“Yotsu-bishi” arranges four rhombus-shaped diamonds into a larger diamond pattern, without any surrounding circle. Its clean geometry made it easy to paint on armour, banners, and kimono, helping it spread widely among samurai and merchant families.

Historical Significance

The crest achieved renown through the Takeda clan of Kai Province, where it symbolised martial resolve. During the Sengoku era, its bold form was painted on battle standards at Kawanakajima and forged onto tsuba (sword guards). Variants later appeared on merchant sails in Sakai City, signalling reliability and wealth.

Symbolism

Four sturdy “seeds” joined edge-to-edge signify a clan both resilient and prosperous, open to opportunities in every quarter.
