Japan undertakes a national project to restore sthe Man-nen Jimeisho perpetual clock.
The culmination of a great technologist's pursuit of his ideals, the Man-nen Jimeisho occupies a special place in history. Japan recently undertook a national project to disassemble and restore the clock and build a replica, with the goal of bringing Hisashige's handiwork back to life. Refurbishing this cultural heirloom, which represents a defining moment in the history of craftsmanship and embodies a genuine passion for artistry, was more than a matter of romantic nostalgia for the past; it was an enterprise of deep significance, for it restored a major symbol of Japanese science and technology. Now, 154 years after it was first built, the masterpiece into which Hisashige poured his spirit of ingenuity has begun marking time for a new era.
