Welcome to Kei’s personal corner of the internet. I’m an engineer based in the Tokai region of Japan, running this site on a home server since 2003.
This English section covers my blog — tech projects, festival reports, cycling trips, and life in Japan. The rest of the site (server tools, help pages, user area) is in Japanese only.
