The Bussokuseki-kahi (仏足石歌碑) is a well-known monument in the Yakushi Temple in Nara, consisting of a traditional Buddha footprint inscribed with twenty-one poems, known as bussokusekika (also known as Bussokuseki no Uta).
The Buddha Foot monument at Yakushi Temple was constructed in 753 and the poems are viewed as being composed around that time.
The poems are written in Man'yōgana, a precursor to kana where Chinese characters are used for their phonetic value, and in Bussokuseki-style.
Named after the poems, Bussokuseki-style is an archaic poetic device in which lines are written in a 5-7-5-7-7-7 mora pattern.
The poems are a valuable inscriptional witness to Old Japanese, otherwise mainly known through later copies of 8th-century manuscripts.
