A Japanese house clock is a mechanical clock made to tell traditional Japanese time.

[edit] How it works

In this type of Japanese clock the mainspring drives the timekeeping mechanism through a cord which it unwinds from a cylindrical drum, and the hour-indicator is attached to a point on this cord. The hour-marks themselves are adjustable in a groove to allow for the different lengths of the hours at different seasons of the year according to the old Japanese system of time-reckoning. The indicator traverses the whole length of the scale in a day and night and is then drawn back again as the mainspring is wound up. The timekeeping is controlled by a verge escapement with balance and spring. The porcelain case bears pictures of the animals with which the various hours of the day and nights were associated on the Japanese system.
