Let’s Learn About William Saito, A Great American Businessperson

William Saito is an American businessperson, software developer, venture capitalist, cybersecurity expert, and writer. Though most people never start their own businesses, let alone successful business entities, Mr. Saito founded his first business while still attending high school, I/O Software.

Back in 1991, when Mr. Saito created I/O Software, the world of computer software was largely unexplored and undeniably underserved. Although there are countless programs available today – many of which are likely completely free – that facilitate the use of Japanese characters on computers with operating systems that run using the English language, I/O Software was the very first such program to pioneer the capability.

I/O Software’s assets were wholly divested by founder William Saito to Microsoft in 2004 following four years of partnership with the world’s largest software company.

After the sale of I/O Software, Mr. William Saito decided to enter the world of venture capitalism – but not in his home country of the United States, where he’d also spent his entire life – in Japan.

While in Japan, William Saito constantly honed his cybersecurity familiarity and technical knowledge. The ongoing effort paid off in 2013 when the Japanese government’s Cabinet Office hired Saito as an advisor in 2013. Mr. Saito’s tenure as the official advisor of the government bureau lasted four years. Throughout that four-year period, he also was named the advisor to Japan’s Ministry of Economy, Trade, and Industry.

On April 20, 2017, Forbes published Mr. William H. Saito’s – Saito’s full name that he writes as – What Fukushima Disaster Taught Me About Risk Management In Cybersecurity.


Just over seven years ago, in March 2011, a nuclear reactor in Fukushima, Japan, exploded, causing a major earthquake that led to a big-time tsunami. The Fukushima Daiichi Nuclear Power Plant was rendered dead alongside countless Japanese citizens that were killed directly from blast exposure, the earthquake, and the major tsunami wave that followed.


Even though the plant was considerably well-managed, it obviously failed. Mr. Saito holds this perspective to everything related to cybersecurity across business endeavors. Cyber-attacks can always render businesses heavily damaged, if not entirely obsolete, a lesson he learned via the unlikely lesson of the 2011 Japanese nuclear reactor disaster.
