Nobuo Ogawa, a local entrepreneur in Japan, started from the pharmacy field after the Second World War then developed it to the Nichia Company. Today, Nichia is a world renowned company in the development of the blue light-emitting diode. Prior to this development, Ogawa of acumen adopted Shuji Nakamura. Nakamura strongly proposed to Ogawa to invest in his research a large amount of money and to allow him to study in the United States. Ogawa immediately accepted it. Nakamura went abroad and after returning home, he researched the blue light-emitting diode. This investment was successful in 1993. Nakamura completed his research of the mass production of the blue light-emitting diode in just four years. Today LED is used as a light illumination everywhere in the world and the blue light-emitting diode has allowed numerous innovations in many useful fields. Owing to the development, Nichia became a world enterprise. Nakamura was awarded the Nobel Prize in Physics in 2014. We wish to expand on the encounter of Ogawa and Nakamura and the successful process of the making of the blue light-emitting diode.
