T he Bank of Japan has come under a lot of fire of late, but there's at least one thing it can be proud of: the work of former employee Rasa Tsuda.

The 30-year-old, who spent three and a half years at the bank before quitting in 2006 to launch a career in the art world, has displayed the kind of entrepreneurial spirit that would surely please the nation's economic czars.

After 18 months cutting her teeth at Gallery Tagboat, a large dealer with an online sales component, Tsuda and a colleague quit to launch an online art dealership called Azito. The site opened just over a year ago.
