Brooklyn-born James Catchpole runs Tokyo Jazz Site, a blog that documents the capital's extensive jazz scene.

Based in his adopted city since 1998, Catchpole established the site in May 2007, when, he says, "after some very basic lessons on what a 'blog' is and what 'domains' are, a Web-savvy friend helped me set up an account and we got the first page up. From there it wasn't long before the jazz content expanded and the look of the site came together."

Posting under the guise "Mr. OK Jazz," Catchpole offers reviews of the city's jazz joints, specializing in the lesser-known hole-in-the-walls that fly below the radar.
