We began the first day of the COD Japan conference with two lectures, held on the 45th floor of the Mori Building at Roppongi Hills, designed by KPF. It was a great vantage point to look down on buildings visited in the last few days. The first lecture was by Masami Kobayashi of Meiji University. The title of his talk was Japan & the Tohoku Rebuilding Efforts.
Professor Kobayashi described how Tokyo had grown through centuries of what can only be called calamities– wars, fires, and earthquakes. Parts of the city were damaged or destroyed and then rebuilt. The city, therefore, has the texture of many eras of development layered on top of one another, creating a weaving of old and new, dense development and open space. He described it as a ‘salami pizza city’.
He went on to describe the enormous damage caused in eastern Japan by the recent (March, 2011) earthquake and tsunami. In helping with the reconstruction of the coastal towns destroyed by the tsunami he was finding a unique role for architects. The key, long-term issues are where and how to restore the communities that were destroyed. One key issue he and others are struggling with is that if you build a sea wall high enough to protect a community, you separate them from their key asset, the sea. The other key issue is a tsunami often destroys part of a community (the part lowest and closest to the ocean), leaving developments further back or on hillsides unharmed. The challenge arises in how to integrate sections of rebuilt areas with the older surviving ones.
Through charettes, his team of students and faculty are working to find alternate solutions. One idea is to raise the land; sounds simpler than it probably is. Another idea is to redevelop the low land but provide clear and easy paths out for people, i.e., lose buildings in future tsunamis but not lives. Yet another solution explored how to break a sea wall into sections that would break up waves yet provide views. I was impresses that his group was working toward real solutions to complex, community-oriented issues. The quality of life obtained in the end for the inhabitants, the fabric of the community, was equally as important as the civil engineering solution to the problem.
The second lecture follows….
