I never thought I would write a post on toilets, but this is worth sharing.
One cannot visit Japan without noticing the sophistication of their water cabinets, and more precisely, the toilets. In comparison to the boring simplicity of our latrines, the japanese throne offers it user a range of services analogous to the rich feature set of luxury sedans: seat warmer, multiple force flushes, silencer, water level control, bidet for men and women, etc. (and that is probably a subset of what is possible without referring to the user guide). The pictography is great.
This raises two questions. The first, why has so much R&D been invested in this specific area and second, why has such an enhanced user experience not been adopted by other countries outside of Japan?
PPS: Yet another example of Japanese ingenuity and efficiency. The below is a public WC in a temple in the mountains. Using the water of the flush to power the tap. So simple, yet so green.
