His last years were among his most productive, with his great series One Hundred Aspects of the Moon (1885–1892), and New Forms of Thirty-Six Ghosts (1889–1892), as well as some masterful triptychs of kabuki theatre actors and scenes.

During this period he also cooperated with his friend, the actor Ichikawa Danjūrō, and others, in an attempt to preserve some of the traditional Japanese arts.

In his last years, his mental problems started to recur.
In early 1891 he invited friends to a gathering of artists that did not actually exist, but rather turned out to be a delusion.
His physical condition also deteriorated, and his misfortune was compounded when all of his money was stolen in a robbery of his home.
After more symptoms, he was admitted to a mental hospital.
He eventually left, in May 1892, but did not return home, instead renting rooms.

He died three weeks later in a rented room, on June 9, 1892, from a cerebral hemorrhage.
He was 53 years old.
A stone memorial monument to Yoshitoshi was built in Mukojima Hyakkaen garden, Tokyo, in 1898.
