Yoshiyuki Nishiyama

Yoshiyuki Nishiyama is the kind of figure who quietly does the work while everyone else is chasing headlines. Born on New Year's Day 1942 in Qingdao and raised in rural Gunma — already a pretty auspicious start — he built a career as a businessman that apparently ran deep enough to earn him the Kōju-Hōshō, Japan's medal awarded to private citizens who donate their own money for the public good. That's not a PR stunt; you actually have to put your own wealth on the line for the community to get that recognition. He founded NAC, took it all the way to the first section of the Tokyo Stock Exchange, sat on the board of Keidanren, and opened the Nishiyama Art Museum for his Utrillo collection — and still, his whole deal seems to be giving without needing the credit.
