In this dialogue between a Japanese professor (Tomio Tezuka) and an inquirer (Heidegger), the possibilities and dangers of a dialogue between Japanese and German culture are discussed. The great danger of this dialogue is that the relation between the two cultures can only be discussed in either of the two languages. Since the Japanese and the Germans speak different languages, they live in two different houses of being. In their journey as “on the way” to language, Heidegger and his Japanese guest come to the conclusion that what is uniquely singular to language, its silent depths, can only be disclosed in a dialogue that speaks from and out of language itself, instead of about it. Only in a dialogue that wants to keep silent can language reveal itself in its stillest depths as saying. Heidegger determines saying in two different ways, as what is said in it and what is to be said. Language as saying hints at being, and reveals in its beckoning and echo the unconcealment of the twofold.
