Bokuo Soun

Bokuo Soun (1903–1991) was a Rinzai master and student of Seisetsu Genjyo. He served as an important link in the transmission chain that connected the nineteenth-century Inzan line to the contemporary era. His most notable student was Omori Sogen, who would go on to become one of the most influential Rinzai masters of the twentieth century.

Through Omori Sogen, Bokuo's lineage reached beyond Japan with the founding of Chozen-ji in Honolulu, the first Rinzai headquarters temple established outside Japan.
