with the majority priced around US$500 for washlet upgrades for existing Western-style toilets. Top-of-the-range washlets, including the ceramic bowl, can cost up to US$5,000. Toto Ltd. is the largest producer of toilets, including washlets, worldwide. Washlets and other toilet related products are also produced by Inax, and Panasonic. The total market worldwide for high-tech toilets was about US$800 million in 1997. The largest producer in this category is Toto, with 65% of the market share, while the second largest is Inax at 25%. The main market for washlets is still in Japan, and Toto reports that overseas sales account for just 5% of its revenue. The primary foreign market is China, where Toto sells over one million washlets each year. In the US for example, sales are well below Japanese levels, even though sales improved from 600 units per month in 2001 to 1,000 units per month in 2003. In Europe, Toto sells only 5,000 washlets annually. While most Europeans would probably regard Japanese washlets as quite a curiosity, the number of such toilets being installed in Europe is increasing. This is mainly for toilets for the handicapped. Depending on the type of disability, handicapped persons may have difficulties reaching the anus region to clean themselves after toilet use. Hence, the introduction of toilets with a water jet cleaner and blow dryer allows such persons to clean themselves without assistance. There are several reasons for low sales outside of Japan. One main reason is that it takes time for customers to get used to the idea of a washlet. Sales in Japan were slow when the device was introduced in 1980. After some acclimatization, sales improved significantly starting in 1985. Around 1990, 10% of Japanese households had a washlet; this number increased to over 50% in 2002. Toto expects a corresponding improvement in foreign sales within a few years. Another factor is the lack of a power supply near the toilet. While virtually all Japanese washrooms have an electric outlet behind the toilet, many foreign bathrooms lack a nearby outlet. In Australia, New Zealand, Ireland, the UK, and many other countries, high current electrical outlets installed in close proximity to water, or where persons may be wet, are prohibited by codes due to possible health and safety concerns. Lastly, the outlet of the toilet (for S-type toilets) is a maximum from the back wall, but Japanese toilets need it to
