Mentioned in a quote from Masao Abe and Norman Waddell near the beginning of DC Genjo Koan study

From interview with Kazuaki Tanahashi - Mel and I have been translating Bokusan’s commentary. [influential late 19thcentury Soto Zen master/scholar]. Bokusan’s commentary is so great. Kishizawa's understanding must have come from him. The Soto scholarship from Dogen is centered around, in my understanding, on Bokusan's understanding. And then Kishizawa refined it, put it in context.

Sōtō Zen in Meiji Japan: The Life and Times of Nishiari Bokusan

Meiji Japan (1868-1912), a period of radical transformation -and Westernization - of Buddhism, and the era of the birth of what is known today as the Soto Sect.

Nishiari Bokusan 西有穆山 (1821-1910) —the teacher of Shunryu Suzuki Roshi’s teacher Kishizawa Ian, the most influential commentator on Dogen in the twentieth century, and the scholar-priest sometimes called the “father of the modern Soto Sect”— is largely ignored in English language writings on Zen despite his tremendous importance.

In this paper, an edition of Jiryu’s MA thesis written under the guidance of the Group in Buddhist Studies at UC Berkeley, Nishiari Bokusan’s life story is presented for the first time in English.  It is told in the context of the persecution and transformation of Buddhism in the Meiji Period, and against the backdrop of the history of the institutional birth of Soto Zen.  This edition includes a preface for the American Sangha.
