Born in Hirashima Village, Owari Province, to a wealthy scholar family who later gave up their status to become farmers, Hosoi spent the first nine years of his life there as a student in a local temple.
It was during this time that Hosoi gained an education in the Chinese classics and when he was a young adult, he began giving lectures to daimyōs and commoners.
After being taught in Nagoya, Hosoi moved to Nagasaki, where he would remain for three years until he was forced to return home to take care of his ailing mother.
[2] In 1780, Hosoi was able to secure a position as a teacher in Owari, where he occupied areas of land to be used as places where he could give his lectures and educate the local people.
The practical emphasis of his teachings, along his focus on the economic conditions of the common person won him many disciples, who gave him the name of Living Buddha.
According to Hosoi's view, when a woman is in her childhood, the parents should refrain from spoiling her in order to keep her from developing a love of luxury, as well as being unable to adjust to the hardships of the married life.
