Abstract
This article describes the prospective and perspective discussions on the philosophy of
Oukan (transdisciplinary science and technology) in our federation. We began to define our principle
and establish the academic foundation of the federation. It is emphasized that our discussion started
with the notion of “system science” and again returns to “system science.” This term must precisely
present our target principle of activity. This article also reports the summary of the discussions and
among presidents of themember societies about the outline and promotion of our activities in 10 years
future.
