After a year, Hokusai's name changed for the first time, when he was dubbed Shunrō by his master. It was under this name that he published his first prints, a series of pictures of kabuki actors published in 1779. During the decade he worked in Shunshō's studio, Hokusai was married to his first wife, about whom very little is known except that she died in the early 1790s. He married again in 1797, although this second wife also died after a short time. He fathered two sons and three daughters with these two wives, and his youngest daughter Ei, also known as Ōi, eventually became an artist and his assistant. "Fireworks in the Cool of Evening at Ryogoku Bridge in Edo" () dates from this period of Hokusai's life.
