Born in 1949 in postwar Japan

In this article, I would like to look back at my life as a researcher of photosynthesis. I was born in 1949, and grew up and was educated in postwar Japan in the 1950s and 1960s. I have studied photosynthesis, in particular Photosystem II, after research experiences in the USA and UK. My study of Photosystem II has continued over 43 years until now. Through the present retrospection, I would like to suggest that all photosynthesis researchers, including the members of the "49ers", many other established scientists, and young students as well, should not simply stay in the lab working hard on their studies and writing papers; but should also do something for the public. People want to learn from us about many critical social issues such as the environment, food, energy and, most importantly, peace. I believe that our knowledge must form an important basis for people to take action to create a peaceful and harmonious human society.
