Keigo Omaki, director of the video website Nippon Teshigoto Zukan (Japan Handwork Encyclopedia), has an almost addictive interest in traditional items made by Japanese craftsmen, and he's not sure why.

"Maybe it's because I played baseball when I was young. It taught me the importance of taking good care of the equipment," Omaki says.

These days he travels nationwide interviewing craftsman and filming their work to archive traditional skills and processes.
