They were known for their military prowess and played significant roles in the political landscape of the time. The clan's influence extended across various regions, particularly in Kyushu, where they established their power. Members of the Tachibana clan often held high-ranking positions in the imperial court and were involved in various military campaigns. Their legacy includes notable figures such as Tachibana no Hiromi, who contributed to the clan's reputation.
