Born in the Kumamoto prefecture, Japan in 1959, Hashimoto worked in the financial industry for 17 years before studying in Tokyo in the department of Arts, Policy and Management, and then getting a job as a curator at the Lalique museum in Hakone, Japan.Hashimoto says: " I created this work for the means of an interface to the people who are yet to know of the extremely grave, but present problem of the world."
One is titled "1945-1998" and shows a history of the world's nuclear explosions. Over the course of fourteen and a half minutes, every single one of the 2053 nuclear tests and explosions that took place between 1945 and 1998 are is plotted on a map. A metronomic beep every second represents months passing, and a different tone indicates explosions from different countries. It starts out slowly, with the Manhattan Project's single test in the US and the two terrible bombs dropped on Hiroshima and Nagasaki that ended World War II. After a couple of minutes or so, however, once the USSR and Britain entered the nuclear club, the tests really start to build up, reaching a peak of nearly 140 in 1962, and remaining well over 40 each year until the mid-80s. Only two nuclear explosions have ever been detonated offensively, both in 1945. Since then, despite more than 2,000 other tests and billions of dollars having been spent on their development, no nuclear warheads have been used in anger.
