Shogen was a learned priest of the Japanese Tendai school in the 14th century. He lectured on the Shikan girei written by Chanjan. Etatsu recorded the content of the lecture and summarized it in the work Shikan girei inokuma sho.
In this book, Shogen criticized various opinions about Shikan, meditation theories of the Chinese Tendai sect. A distinguishing characteristic of his claim is that his theory about Shikan is mixed with a doctrine of esoteric Buddhism of Japanese Tendai sect.
