What is "zenshuji"

Zenshuji Soto Mission (Japanese: ), established in 1922 in the Little Tokyo section of Los Angeles, California, was the first Soto Zen Buddhist temple in North America. Today, it is the North American headquarters for Soto Zen, under the guidance of Sotoshu Shumucho (the headquarters of Soto Zen in Japan), and is a direct branch of Eiheiji and Sojiji (the two head temples in Japan).
