Soyen Shaku
Soyen Shaku put him in charge of Ryōbō Kai, and gave him the hermitage-name "Ryobo-an". Sokatsu opened the hermitage for lay-practice, opening up the possibility of dharma transmission to lay practitioners. At the end of World War II Sokatsu closed Ryōbō Kai, but the lay practice was continued by his dharma heir Koun-an Roshi.
