Tange also joined the group whilst in Tokyo on a travelling fellowship from the Graham Foundation. By day Asada canvassed politicians, business leaders and journalists for ideas, by night he met with his young friends to cultivate ideas. Asada was staying at the Ryugetsu Ryokan in Asakusa, Tokyo and he used it as a meeting place for progressive scholars, architects and artists. He often invited people from other professions to give talks and one of these was the atomic physicist, Mitsuo Taketani. Taketani was a scholar who was also interested in Marxist theory and he brought this along with his scientific theories to the group. Taketani's three stage methodology for scientific research influenced Kikutake's own three stage theory: ka (the general system), kata (the abstract image) and katachi (the solution as built), which he used to summarise his own design process from a broad vision to a concrete architectural form. The group also searched for architectural solutions to Japan's phenomenal urban expansion brought about by its economic growth and how this could be reconciled with its shortage of usable land. They were inspired by examples of circular growth and renewal found in traditional Japanese architecture like the Ise Shrine and Katsura Detached Palace. They worked in coffee shops and Tokyo's International House to produce a compilation of their works that they could publish as a manifesto for the conference. The conference ran from 11–16 May 1960 and had 227 guests, 84 of whom were international, including the architects Louis Kahn, Ralph Erskine, B. V. Doshi, Jean Prouvé, Paul Rudolph and Peter and Alison Smithson. Japanese participants included Kunio Maekawa, Yoshinobu Ashihara and Kazuo Shinohara. After his 13 May lecture, Louis Kahn was invited to Kikutake's Sky House and had a long conversation with a number of Japanese architects including the Metabolists. He answered questions until after midnight with Maki acting as translator. Kahn spoke of his universal approach to design and used his own Richards Medical Research Laboratories as an example of how new design solutions can be reached with new thinking about space and movement. A number of the Metabolists were inspired by this. The Metabolism name Whilst discussing the organic nature of Kikutake's theoretical Marine City project, Kawazoe used the Japanese word shinchintaisha as being symbolic of the essential exchange of materials and energy between organisms and the exterior world (literally metabolism in a biological sense.)
