In Japan, the word ‘creativity’ is often used to refer to the greatest talent and the works of special people such as a great scientist, writer, architect, painter or musician. The number of Nobel Prize winners who are recognised as greatest scientists has increased rapidly during the last 20 years (16 winners). This number is second largest to the US. Why has the number suddenly increased? Several reasons can be inferred. The number of university students has increased rapidly since the 1960s. Many brilliant students who graduated from Japan’s universities then studied in American universities or research institutes and discovered themes connected to the Nobel Prize. After much trial and error, they finally completed these studies. Another reason may be attributed to their dexterity or the ability to think out unusual methods to solve problems in their areas.
