Three sparrows in a bamboo circle trucker hat

Takeno maru ni sanwa suzume / Bamboo crest / This is a representative family crest of the Kajuji family (Kajuji family), one of the most famous families among the court nobles. This crest was treated as a prestigious crest, second only to the Konoe family's peony crest, and was not allowed to be used by ordinary families. The Kajuji family only granted this crest to powerful clans such as the Nagao, Date, and Mogami. Therefore, the current distribution of this crest is mostly limited to the regions where these clans were located. The samurai families that received this crest from the Kajuji family used a crest with two sparrows, which contrasts with the three sparrows used by the court nobles.
