The BBC's Michael Fitzpatrick writes about the relative technological backwardness of many sectors of the Japanese economy, and their reasons for remaining so.
Yoji Otokozawa, president of Tokyo-based IT consultants Interarrows, says Japan Inc. is poor in digital literacy because small businesses, not multinationals, rule the country.
"The hub of the matter is that you have to understand how SMEs [small and medium-sized enterprises] dominate the Japanese business landscape," he says.
SMEs account for 99.7% of Japan's 4.2 million companies, according to Japan's Ministry of Economy, Trade and Industry. So the world's third biggest economy is driven by minor establishments, not the giants everybody knows outside of Japan.
These SMEs are often conservative, if not downright Luddite, says Mr Otokozawa.
"They usually use postal mail, or fax for their communications. We sometimes receive a fax, written by hand which means such firms don't even use word processing software like Word."
