Issey Miyake (at Design Site 21_21, before his show of work with Irving Penn) about the earthquake in Tohoku. Well, less about the earthquake as such, and more a support for the people and craftsmen and women of the area, because Tohoku is the area where a lot of the companies, dyers, cutters, knitters, experimenters, textile-makers that Miyake works with are based. The area has that tradition of work, and an introduction to the display of his and their work describes "tradition" as "research with perseverance" and involving innovation. A neat definition.
On at the same time, I missed the Tokyo Art Fair (at the International Forum) but you can see a review on Tokyo Art Beat.
