Yuichi Yamamoto: He launched this blog in August 2004 when he was 68 years old. He is a Japanese citizen - but only technically so. He spent his entire career in the international business scene from 1959 through 2005, mostly as a financial manager. Those years encompassed the high-growth era of the '60s and '70s, the bubbling '80s and the post-bubble doldrums which led Japan to fall terminally ill.
Dai Kashio: This site has been technically supported by him since its beginning. He is a 35-year-old Japanese systems engineer, currently working for several projects to develop epidemiological applications.
Both bloggers are based in the port city of Yokohama.
