There exists a work dated Tenpo 6 (1835).
He passed away in Meiji 3 (1870) at the age of 70.
Gassan Sadayoshi was the teacher of Gassan Sadakazu and Gassan Sadakatsu, and is said to have taught Sadakazu the fundamentals.
It is thought that he repeatedly attempted to produce the Gassan-hada.
According to the Shinshinto Taikan, this work is considered a daimei (signed on behalf) by Sadakazu, made when Sadayoshi was 83 years old.

Historical Background: The Bunkyu era (1861–1864) of the Edo period corresponds to the turbulent Bakumatsu period, between the Man’en and Genji eras.
It was the time of Emperor Komei and the 14th shogun Tokugawa Iemochi.
Events such as the Bunkyu Reforms led by Shimazu Hisamitsu and the Coup of August 18 intensified the conflict between forces seeking to restore shogunal authority and those advocating opening the country or revering the emperor, placing this era at the height of political unrest.
