Kusha (Buddhism)

The Kusha-shū (^?) was one of the six schools of Buddhism introduced to Japan during the Asuka and Nara periods. Along with the Tattvasiddhi school (Jōjitsu-shū) and the Risshū, it is a school of Nikaya Buddhism, which is sometimes derisively known to Mahayana Buddhism as "the Hinayana".

A Sarvastivada school, Kusha-shū focussed on abhidharma analysis based on the "Commentary on the Abhidharmakośabhaṣya (倶舎論^?)" by the fourth-century Gandharan philosopher Vasubandhu. The school takes its name from that authoritative text.

Names commonly associated with the Kusha-shū are Dōshō (道昭 638–700), Joe (644–714), Chitsū (智通 ?–?), Chitatsu (智達 ?–?), and Genbō (玄昉 ?–746).
