A trip to the Science Museum in London is one of our favourite family outings. However, looking past the steam trains and model tractors, there is at least one gallery that merits inclusion here: the exhibit Measuring Time, which includes a whole display on Japanese clocks.
Under the old Japanese system, periods of daylight and darkness were each divided into six intervals, with day and night hours being of different lengths. In many cases, the clocks are adjustable to reflect that these timings changed with the passing seasons. There is great variety in the timepieces on show: tall pillar clocks, imposing house clocks, smaller table clocks and bracket clocks. I especially enjoyed the decorative metalwork, which in some examples is highly ornate. The clocks are behind glass, so apologies for the glare on some photos.
