This past week I've been down in Kyoto primarily doing research for the second book, but also fitting in time to see some things unrelated to Musashi. Here's some photos, featuring locations that may or may not turn up in Hours (click and hover your mouse over the picture for further info):
Most of the real interesting stuff, like the Buddhas in the Sanjusangendo hall for example, are forbidden from being photographed so I can't really share with you all I saw. Kyoto is a real lovely city though, unique in Japan in that it was not razed flat in World War 2 and so still retains its history. It's not the first time I've been, and if you're going to go to Japan I would recommend it ahead of Tokyo.
Currently I'm halfway through the second draft of Hours of the Dog. Got lots of fresh inspiration here, and lots of my questions answered. Time to push on.
