By 1800, Hokusai was further developing his use of ukiyo-e for purposes other than portraiture. He had also adopted the name he would most widely be known by, Katsushika Hokusai, the former name referring to the part of Edo where he was born, the latter meaning 'north studio', in honour of the North Star, symbol of a deity important in his religion of Nichiren Buddhism. That year, he published two collections of landscapes, "Famous Sights of the Eastern Capital" and "Eight Views of Edo" (modern Tokyo). He also began to attract students of his own, eventually teaching 50 pupils over the course of his life.
