Japanese philosophy
Some have argued for an origin of "Dasein" in Chinese philosophy and Japanese philosophy: according to Tomonobu Imamichi, Heidegger's concept of "Dasein" was inspired—although Heidegger remained silent on this—by Okakura Kakuzo's concept of "das-in-der-Welt-sein" (being-in-the-worldness, worldliness) expressed in "The Book of Tea" to describe Zhuangzi's Taoist philosophy, which Imamichi's teacher had offered to Heidegger in 1919, after having followed lessons with him the year before. Parallel concepts are also found in Indian philosophy and in Native American lore.
