Okakura Kakuzō
After graduation, Yokoyama spent a year teaching at "Kyōto Shiritsu Bijutsu Kōgei Gakkō" (the predecessor to the Kyoto City University of Arts) in Kyoto, studying Buddhist painting. Around that time, he started to use his "Taikan" pseudonym. He returned to Tokyo in 1896 as assistant professor at the "Tōkyō Bijutsu Gakkō". He resigned that position only a year later, when his mentor, Okakura Kakuzō (aka Okakura Tenshin), was forced to resign for political reasons, and joined Okakura in establishing the Japan Fine Arts Academy ("Nihon Bijutsuin").
