There were two generations of artists who signed Tankasai Motoaki (both fl. circa 1800). This example seems to be the work of the first master. He was born into the Suzuki family, was the nephew of Oyama (Taizan) Motozane I (1741-1830), and became his student. He later took the Oyama family name. He worked at Mito in Hitachi Province, as did most of the artists of this large school.
