In 1963, Japan’s government decided to build a planned scientific community about 35 miles north of Tokyo that would meet the country’s growing demand for high-tech research and technology. Known as Tsukuba Science City, the site today is home to roughly 150 research, educational, and high-tech business institutions. From March to October of 1985, Tsukuba also hosted a world’s fair called Expo ‘85, which was the sole focus of our next Computer Chronicles episode.
