Japan's toilet makers flush with success

Updated: 2010-08-27 14:58

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.

The latest "intelligent" model, manufactured by market leader Toto, goes a step further and isn't for the faint-hearted: It offers its users an instant health check-up every time they answer the call of nature.

Designed for the housing company Daiwa House with Japan's growing army of elderly in mind, it provides urine analysis, takes the user's blood pressure and body temperature, and measures their weight with a built-in floor scale.

"Our chairman had the idea when he was at a hospital and saw people waiting for health checks. He thought it would be better if they could do the health tests at home," says Akiho Suzuki, an architect at Daiwa House.

Toto's engineers developed a receptacle inside the basin to collect the urine for sugar content and temperature checks, and an armband to monitor blood pressure. The readout is displayed on a wall-mounted computer screen.

"With the current model, your data is sent automatically to your personal computer, and then you can e-mail it to your doctor," Suzuki said. "In the next generation model, the data will be sent automatically to family members or doctors via the Internet."

The electronic marvel, called the "Intelligence Toilet," is capable of storing the data of up to five different people and retails for 350,000 to 500,000 yen (about $4,000 to $6,000) in Japan, she said.

"For now our customers are essentially middle-aged and senior people. But we hope the young generation will also become more health-conscious."

The model is the latest advance in a string of sophisticated toilets, known as "washlets" in Japan, which have become ubiquitous in recent decades.

The first models were imported from the United States, where they had been used mainly in hospitals, and quickly became standard in Japan in the booming 1980s, finding their way into at least 70 percent of Japanese homes.

First-time foreign visitors to Japan are often baffled by the complexity of Japanese high-tech toilets, which feature computerized control panels, usually with Japanese language instructions as well as small pictograms.

Standard functions include heated seats, water jets with pressure and temperature controls, hot-air bottom dryers and ambient background music.

A function called "otohime" (literally "princess of sound") produces a flushing sound to cover bodily noises. A portable gadget is available for customers who want to use it on the go, in restrooms far away from home.

In most recent toilet models, the lid automatically lifts when a user enters the restroom. Men can then push a button to flip up the seat.

As soon as the user leaves the room, both the seat and lid automatically glide back into horizontal position, a clever feature that can preempt potential conflict between male and female members of the same household.

Toto engineer Atsuko Kuno said that the auto-lids do more than promote marital harmony and also have "a real function."

"The auto-lid was not invented for convenience but for older people and young children. They don't have to bend down to lift it," he said. "Only later did we discover that it was quite convenient, so it spread into general use."

In recent times, Japanese toilets have also become more environmentally friendly, and most new models now use less than five liters (1.3 gallons) per flush, compared with 13 liters just a few years ago.

Inax, Toto's main rival, also claims many recent advances, some of which it has proudly showcased at the Japanese pavilion at the Shanghai World Expo.

"Until 2001, there was a water tank behind the toilet, but customers were complaining that it was difficult to clean it. Inax was the first maker to get rid of the tank for home toilets," said engineer Ichiro Kojima.
