There will come an age when our average life expectancy will reach 200 years.

I'm the king of debt.

Traditional companies have to start looking into themselves to offer more opportunities in their companies by starting new subsidiaries and joint ventures.

Mankind had the agricultural revolution, the industrial revolution, and now this third one, the information revolution.

I think I became an entrepreneur because I have my way of doing business... to do that, you have to have your own company. But if you have your own company, you're an outsider in the Japanese business world. It's difficult. But that's life.

My original intent for investing into Sprint - the main strategy was to buy Sprint and T-Mobile at the same time, so we'd have a critical mass to fight against AT&T and Verizon. The U.S. government didn't accept that. They rejected it. So my fundamental strategy was broken.

If Japanese cannot have new babies quick enough, then the government should start importing workers faster.
