It's good to have high-quality competition. It helps drive research forward at a faster pace.

Basically, I like research because research is like to solve the quiz, you know. Always there is a problem, and I have to solve the problem. So I like those patterns. It's almost like research is sort of in a quiz.

I am thankful to Nichia Chemical Corporation and its founder Nobu Ogawa, who gave me the research opportunity to create a blue LED.

If Japanese companies don't reform drastically and implement English as their daily business language, the economy will only continue to contract.

The LED light bulb is more than ten times the efficiency of regular incandescent lighting, so it can save the world hundreds of billions of dollars in electricity costs.

My dream was to work for one of the big electronics companies like Sony or Panasonic.
