Professor Emeritus at Toyo Univerisity, Tokyo. Ph.d. in Philosophy in Department of Philosophy, University of Munich. Habilitation at the University of Bochum.
He taught Philosophy and Japanese in Department of Economic Science at University of Witten-Herdecke in Germany (1990-94) and was Professor of Philosophy at Toyo University until 2013.
His interests of the research of philosophy are in the field of Husserl's phenomenology and the philosophy of Buddhism. He focuses on the theme of time and the Other, which is phenomenologically evident in the first part, Time and the second part Other in his book Genese der Zeit aus dem Du (2018). The theme of Other, phenomenologically, the question of the transcendental grounding of intersubjectivity has been criticised unresolved by subsequent phenomenologists, such as Heidegger, Scheler and Levinas. He rejects these criticisms as misrecognition of the concept of pasasive intentionality, which opens up the new field of research of "the phenomenology of the unconscious" in Husserl's genetic phenomenology.
The passive intentionality of the intercorporarity makes emotional, pre-linguistic communication possible, only through this can linguistically articulated communication be realised.
His phenomenological oriented research of intercultural philosophy shows the possibility of refounding intercultural, social philosophy on the basis of Husserl's genetic phenomenology.
