Hiromi Hosoya is teaching an advanced options studio at Harvard University’s Graduate School of Design. The studio with the title “New Metabolism” is researching possibilities and generating projects for redeveloping the site of the World Exhibition 1970 in Osaka. Based on a masterplan by Kenzo Tange, this exhibition was the first time that the ideas and design strategies of the Metabolist Movement in Japan became visible to an international audience. The exhibition was a great success; its attendance numbers were topped only by the Expo 2010 in Shanghai. Recently, the prefecture of Osaka launched a public tender for the redevelopment of the site as one among several urban renewal projects aimed at repositioning the city and the region.
