A Japanese house clock is a mechanical clock made to tell traditional Japanese time. This striking clock has a rotating dial provided with adjustable indicators for showing the time on the old Japanese system in which the periods of daylight and of darkness are each divided into six intervals.

[edit] How it works

A fixed hand is employed and the dial rotates in a clockwise direction once a day. The characters indicating midday and midnight are fixed at diametrically opposite positions on the dial, but in order to allow for the difference in the lengths of the day and night ‘hours’ at different seasons of the year, each remaining hour-mark is mounted on a small plate which slides in a grooved ring in the dial. The clock is spring-driven and controlled by a escapement and ‘bob’ pendulum. It strikes on the usual Japanese system, the sequence of strokes from midnight to noon being 9, 1, 8, 2, 7, 1, 6, 2, 5, 1, 4, 2.
