Among the descriptions of "Nihon Sandai Jitsuroku," what is noteworthy is the one stating that Sangaku performed in 880 as the entertainment of sumai no sechie (ritual performances of sumo at the Imperial court) made people burst into laughter since its performers were almost like fools.
中でも元慶4年（880年）に相撲節会の余興として演じられた散楽は、演者がほとんど馬鹿者のようで、人々を大いに笑わせたとある。
