To prepare for his stay in Japan, he studied Japanese at the university in Berlin, along with philosophy and physics.
He has translated works of Dōgeneral and Kōdō Sawaki, and has authored one book in German and several books in Japanese. During his studies, he spent one year at Kyoto University and learned for the first time about Antai-ji. At age 22, he spent six months there as a lay practitioner.
After obtaining the transmission of dharma (shihō) from his teacher Miyaura Rōshi, Muhō decided to live as a homeless monk in a park in central Osaka, where he led a zazen group in 2001.
After six months though, in February 2002, he learned of the sudden death of his teacher and was called back to Antai-ji. He succeeded his teacher as the ninth abbot in the spring of that year.
