[ ABOUT ]
About Hidekazu Ishikawa
An independent publisher, developer, and writer connecting the web, media, and lived experience.
For more than 20 years, I have built websites and enterprise systems. Today, I run six publications, develop open-source tools, use AI and automation in daily work, and write from first-hand experience. This site brings that work together and shows where I can contribute.
[ EXTERNAL WRITING ]

[ HISTORY ]
The path here.
After high school I studied in California, then attended art school in Japan and worked as an artist in Berlin. Following an exhibition in New York, I returned to Japan. Building a website for my own art introduced me to web development, which became the beginning of more than two decades of work.
[ ROUTE ]
- California / study abroad
- Tokyo / art school
- Berlin / art activity
- Web / self-built site
[ BACKGROUND ]
What I have kept doing.
The work began with a site I built for myself.
For more than 20 years I have moved between commissioned web and business-system development and media I operate myself. Planning, implementation, writing, photography, measurement, and improvement remain connected parts of one practice.
