I met Ryuhei Kawada any number of years ago. He looked alot younger then than he does in this photo care of AFP.
He had come to the press club, the Foreign Correspondents' Club of Japan to participate in a press conference about Japan's tainted blood scandal. (A number of haemophiliacs had been infected with HIV via blood transfusions and he was campaigning for those responsible to be held accountable.)
It could be said Japan had been slower than some other countries to understand that AIDS / HIV was not so easily transmitted. The memory that stands out for me still, even today, is shaking his hand at our meeting, and seeing an expression of shock, even hesitancy cross his face and body; just before he stepped forward to shake my hand.
