Kodo Sawaki Roshi has been described as, "like an ancient Zen master: fearless and unconventional", by his disciple Uchiyama-roshi. By age 7, both his parents had died, an uncle who adopted him had also died and he was adopted by a professional gambler. At age 16, he went to Eihei-ji aspiring to become a monk. The next year he was ordained by Koho Sawada, abbot of Soshin-ji, and given the name, "Kodo". In 1923, he began travelling around Japan giving lectures and leading sesshins (retreats). Because of his resistance to establish himself in a temple, he was known as Homeless Kodo. He became a professor of Zen literature at Komazawa University in 1935 and taught there until 1963. He established Antai-ji Shichikurin Sanzen Dojo in 1949, retired there in 1963, and he died two years later, on December 21st, 1965 at the age of 86.

Kosho Uchiyama Roshi is one of the most highly respected modern Japanese Zen Masters. In 1912, he was born in Tokyo, Japan. He received a Master's Degree in Western philosophy from Waseda University in 1937 and was ordained as a Soto Zen priest in 1941 under Kodo Sawaki-roshi. Upon Sawaki-roshi's death in 1965, Uchiyama-roshi became the abbot of Antai-ji, a monastery and temple then located in Kyoto, Japan. Contrary to his teacher, he did not travelled very often, but tried to stay at Antaiji with his disciples as much as possible. In 1975, he retired from Antai-ji and lived with his wife at Noke-in, a small temple outside Kyoto until his death on March 13, 1998. He wrote about 20 books about Zen, including some translations of Dogen Zenji's texts into modern Japanese. Although he never left Japan, he greatly influenced many Western practitioners.

Shohaku Okumura was born in Osaka, Japan in 1948. He studied Zen Buddhism at Komazawa University in Tokyo and was ordained by Kosho Uchiyama-roshi in 1970. They practised together until 1975, when Okumura-roshi came to the United States. After practising at the Pioneer Valley Zendo in Massachusetts until 1981, he returned to Japan, where he began translating Dogen Zenji's and Uchiyama-roshi's writings into English. Okumura-roshi was a teacher at the Kyoto Soto Zen Center and later at the Minnesota Zen Meditation Center in Minneapolis, Minnesota, and has led sesshins and Dharma study groups in the United States, Japan, Europe and Latin America. From 1997 to 2010 he has been director of the Soto Zen Education Center in Los Angeles, an office of the Administrative Headquarters of the Soto Zen School of Japan. The office has since changed its name and the location; today it is in San Francisco and is called Soto Zen Buddhism International Center. He lives and practices at Sanshin Zen Community in Bloomington, IN.
