One prominent example of Tokyo's creative worlds continuing to blend is the growing number of contemporary art spaces holding architecture exhibits. Tokyo Opera City Gallery had their Jean Nouvel exhibit, the Mori Museum and the National Museum of Western Art have done well with Le Corbusier, and now we have "Architect Tokyo 2009," with some of Japan's best contemporary galleries participating.

Crossovers like this shouldn't be surprising. Architecture and contemporary art share more than a few similarities. But what has some gallerists' attention is just how popular these exhibits really are. And as Edan Corkill wrote last year, architecture can be a huge draw.

This seems to go double for men. Wandering through Tomio Koyama Gallery's "Before Architecture, After Architecture" exhibition last weekend (detail of a mock-up pictured above), I noticed that nearly everyone viewing the video installation and perusing the dozens of photographs and mock-ups was male. What does that say about gender and the nature of creative minds? Build your own theory.
