In Japan, the global leader in high-tech toilet design, the latest restroom marvel should come with a health warning for hypochondriacs -- it doubles as a medical lab that can really spoil your day. Japanese toilets have long and famously dominated the world of bathroom hygiene with their array of functions, from posterior shower jets to perfume bursts and noise-masking audio effects for the easily-embarrassed.
Today there are colorful portable gadgets and iPhone applications to cover up the sounds people make when using the toilet, but a museum here has a large bronze urn dating from the 19th century that could be the earliest form of such devices.
A new state of the art toilet in Japan reflects an unusually high level of attention to detail and technological innovation. A full array of Japan's newest high tech lavatories. The top of the range toilet is equipped with a far wider range of functions than earlier versions. The user is able to control the trajectory of the jet of water, which emerges from a retractable duct located within the toilet bowl. "Move" and "massage" functions are also available and the velocity of the stream can be adjusted.
