Born Hara Ariyoshi in or around 1785, Zaizen was the third son of Hara Zaichū. Like his brothers, Zaizen studied painting under his father and was active within the atelier. He also painted under the name Shishi (子至). Although his older brother Zaimei succeeded as Hara head, Zaizen was well known in Kyoto art and court circles. His name appears, for example, in the 1830 edition of the "Heian Jinbutsushi". Today, his paintings can be seen at the Kyoto National Museum.
