In theorizing the inter-personal basis of sustainability, Watsuji’s theory of fudo as intertwined with “who we are” is enlightening. Its elucidation of climate as pertaining to the dimension of the collective first opens a space for the reflection of the communal as circumscribed by a fudo. However, if his philosophy remains at the level of the collective characterized by the distinctiveness of the fudo of a region, it would share the same fate as any discourse on regionalism. The conservative insularity of the collective to the point of failing to acknowledge the presence of the others has been identified as the fundamental pitfall of regionalism. While it was not completely fledged, Watsuji’s philosophy transcends the insularity of fudo and the communal to arise to the plane of the trans-fudo and the public. It is the plane where issues such as typicality of human praxis beyond regional boundaries surfaces, and its dialectical interaction with the idiosyncrasies of the region of which fudo is a vital part acquires significance. Watsuji’s theory of fudo in this manner leads us to revisit Critical Regionalism, which sought to a degree reciprocity between the regional and the universal, or the trans-regional, a criticism of Critical Regionalism, and a discourse that deals with typicality of the ideals of the human living.
