Eco-phenomenology developed from the effort of a number of continentally-oriented philosophers exploring the thought of decisive authors in the phenomenological tradition, such as Husserl, Heidegger, and Merleau-Ponty, with the purpose of offering a different insight into environmental issues than those predominant in Anglo-American philosophy. This initiative has proceeded not only from Western scholars but has had a resonance also in the distant philosophical tradition of Japan. The present contribution seeks to deepen the thought of a central figure for Japanese phenomenology: Nishida Kitaro. Nishida, indeed, was the first to introduce Husserlian thought in Japan and to seriously dialogue with the German phenomenologist from a Zen-oriented point of view. The purpose of this effort is to throw light on the theoretical origins of modern Japanese (eco)phenomenological thought, in order to grasp also its differences with Western eco-phenomenology, as led by Nishida's Buddhist reading of Husserl's works.
