The purpose of this paper is to consider the building process of D.T. Suzuki(1870‒1966)’s Pure Land thought by dividing the process into three parts, that is, one is a period that Suzuki accepted the fundamental Pure Land literature in 1920’s, another is a period that he tried analysis by psychological method in 1930’s and the other is a period that his Pure Land thought developed into his Buddhist philosophy actually in 1940’s. Another purpose is to verify that Suzuki’s Pure Land thought was based on Ippen’s one. Traditional studies didn’t really focus that, but he accepted Ippen in relatively early time. Suzuki was a thinker who emphasized common religious experiences between Zen and Pure Land thought. He focused on Ippen’s thought because it was close to his view of religious experiences. He developed his Pure Land thought through understanding Ippen, especially an immediate integration of sentient beings and dharma. After he accepted Ippen by literature for the first time, he inspected that the case of seeing from psychological aspect, the immediate integration is the same experience as enlightenment in Zen. Suzuki passed through the consideration like this, then established his contradictory logic in 1940’s. It became the inclusive logic that contained his all arguments. Finally, he found Myoko-nin who are firm believers on Shin Buddhism. They were the very people that embodied Suzuki’s thought that had been fostered since adaptation of Pure Land thought.
