This essay explores the ontological movement of poetry, its language and words, by establishing a dialogue with the thought of three Japanese thinkers, Ki no Tsurayuki, Motoori Norinaga and Fujitani Mitsue, and the German philosopher Martin Heidegger. The overall purpose, as we progress from one to the other, is to present, explore and disclose a horizon where poetry gradually becomes the locus of a philosophy of language that places it at the genesis of mutual understanding, ethics and, thus, of community.
