High tech Japanese bidets
The modern toilet in Japan, commonly known in Japanese as Washlet (ウォシュレット) or as warm-water cleaning toilet seat (温水洗浄便座: onsui senjō benza) is the most advanced type of toilet worldwide, showing a dazzling array of features. The TOTO product Washlet Zoe is listed in the Guinness Book of Records as the world's most sophisticated toilet with seven functions. However, as the model was introduced in 1997, it is now likely to be inferior to the latest model by Toto Neorest. The idea for the washlet came from abroad, and the first toilet seat with integrated bidet was produced outside of Japan in 1964. The age of the high-tech toilet in Japan started in 1980 with the introduction of the Washlet G Series by TOTO, and since then the product name washlet has been used to refer to all types of Japanese high-tech toilets. As of 2002, almost half of all private homes in Japan have such a toilet, exceeding the number of households with a personal computer. While the toilet looks like a Western-style toilet at first glance, there are a number of additional features, such as blow dryer, seat heating, massage options, water jet adjustments, automatic lid opening, flushing after use, wireless control panels, heating and air conditioning for the room, et cetera, included either as part of the toilet or in the seat. These features can be accessed by a control panel that is either attached to one side of the seat or on a wall nearby, often transmitting the commands wirelessly to the toilet seat.
