Where will Japan's toilets stop?

As one sits on Toto's Intelligence Toilet, it extends a little cup to take five cubic centimeters (0.15 fluid ounces) of urine, which is sent through a tube to a hidden sensor to measure sugar levels. The cup is then cleaned automatically. While doing your urine check-up, you can also pop open a built-in box next to the toilet paper roll and take out the velcro to wrap around your wrist to check blood pressure.

Also on offer are a scale under the floor and two bars above a washstand that can measure how fatty your body is. All the test results are displayed on a single panel and fed into a personal computer. The machine can accumulate individual records of a family and offers the option of blocking other users from seeing your data. "But our original idea is to have the mother adjust dining menus in accordance with the health of her family," a spokeperson says.

Intelligence Toilet costs between 380,000 and 562,000 yen (3,500 to 5,170 dollars) .
