It looks like the perfect business opportunity. Every house has one. Everyone uses them. And one Japanese company is making the most technologically advanced products of their kind.
But while the world may beat a path to your door for building a better mousetrap, Toto Ltd has found that selling a better toilet requires more patience.
Toto, the world's dominant maker of high-tech loos, made toilet history in 1980 when, improving on a US model that combined the bidet and the toilet, it produced the "washlet" -- bringing warm water to the user's nether regions.
"We did what others were reluctant to try -- we brought electronics into the water closet," said Hiroshi Kobayashi, Toto's general manager of restroom product research.
Sometimes dubbed "super-thrones," top-of-the-line washlets now come with wall-mounted control panels as sleek and complex as those of stereo systems.
Their manifold buttons allow adjustment of the nozzle position, water pressure and type of spray, plus blow-drying, air purification and seat warming for those cold winter mornings. Water and seat temperatures are adjustable.
The controls can also be set so the lid rises as the toilet is approached.
Japan has embraced the high-tech toilet. Government statistics show that combined toilet/bidets are now installed in 52 percent of Japanese homes compared to just 14 percent in 1992.
Toto -- which employs around 1,500 engineers -- dominates that market with a 65 percent share. Its closest rival, Japan's Inax Corp, trails at 25 percent. Numbers for Japan's overall toilet market share are similar.
But where Sony's Playstation, Toyota Corollas and Pokemon have all blazed paths into western popular culture, Toto's high-tech thrones have not traveled well.
Toto officials blame matters both cultural and practical.
A relatively long history of flush toilets in the US and Europe -- around 100 years -- has resulted in many competitors and cheap toilets.
Westerners just aren't used to shelling out hundreds or even thousands of dollars for high-tech versions.
Most Western bathrooms also lack an electric socket near the toilet, something that people in Japan, where central heating is rare, were keen to install when the seat-warmer was introduced.
But after making some inroads in the US with more standard models, especially with the advent of low-flow toilets in the 1990s, Toto's washlets are starting to make an impression.
Its US washlet sales, which began some eight years ago, have risen to over 1,000 units a month this year from 600 two years ago.
"It's not the same amount of numbers but the trend is very similar to what we saw in Japan 20 years ago -- low figures for about five years and then a sharp J-curve. We have great expectations for US sales next year," Kobayashi said.
But marketing toilets is not easy. Building showrooms is expensive and some analysts estimate it will take another five years before overseas revenues, now only 5 percent of Toto's total sales, climb to 10 percent.
And some cultural barriers seem to be just too hard to break -- witness the European market, where Toto has only one distributor and sells a mere 5,000 washlets annually.
"You'd think that because Europeans are used to the bidet, they'd be more interested. We just don't know why they aren't," said Kobayashi.
Some analysts even argue that tackling cultural norms isn't worth the effort and that Toto would be better off pulling its washlets out of the US and Europe altogether and concentrating on more receptive Asian markets like China.
WEAKER ACTIVITY: The sharpest deterioration was seen in the electronics and optical components sector, with the production index falling 13.2 points to 44.5 Taiwan’s manufacturing sector last month contracted for a second consecutive month, with the purchasing managers’ index (PMI) slipping to 48, reflecting ongoing caution over trade uncertainties, the Chung-Hua Institution for Economic Research (CIER, 中華經濟研究院) said yesterday. The decline reflects growing caution among companies amid uncertainty surrounding US tariffs, semiconductor duties and automotive import levies, and it is also likely linked to fading front-loading activity, CIER president Lien Hsien-ming (連賢明) said. “Some clients have started shifting orders to Southeast Asian countries where tariff regimes are already clear,” Lien told a news conference. Firms across the supply chain are also lowering stock levels to mitigate
Six Taiwanese companies, including contract chipmaker Taiwan Semiconductor Manufacturing Co (TSMC, 台積電), made the 2025 Fortune Global 500 list of the world’s largest firms by revenue. In a report published by New York-based Fortune magazine on Tuesday, Hon Hai Precision Industry Co (鴻海精密), also known as Foxconn Technology Group (富士康科技集團), ranked highest among Taiwanese firms, placing 28th with revenue of US$213.69 billion. Up 60 spots from last year, TSMC rose to No. 126 with US$90.16 billion in revenue, followed by Quanta Computer Inc (廣達) at 348th, Pegatron Corp (和碩) at 461st, CPC Corp, Taiwan (台灣中油) at 494th and Wistron Corp (緯創) at
NEGOTIATIONS: Semiconductors play an outsized role in Taiwan’s industrial and economic development and are a major driver of the Taiwan-US trade imbalance With US President Donald Trump threatening to impose tariffs on semiconductors, Taiwan is expected to face a significant challenge, as information and communications technology (ICT) products account for more than 70 percent of its exports to the US, Chung-Hua Institution for Economic Research (CIER, 中華經濟研究院) president Lien Hsien-ming (連賢明) said on Friday. Compared with other countries, semiconductors play a disproportionately large role in Taiwan’s industrial and economic development, Lien said. As the sixth-largest contributor to the US trade deficit, Taiwan recorded a US$73.9 billion trade surplus with the US last year — up from US$47.8 billion in 2023 — driven by strong
ASE Technology Holding Co (ASE, 日月光投控), the world’s biggest chip assembly and testing service provider, yesterday said it would boost equipment capital expenditure by up to 16 percent for this year to cope with strong customer demand for artificial intelligence (AI) applications. Aside from AI, a growing demand for semiconductors used in the automotive and industrial sectors is to drive ASE’s capacity next year, the Kaohsiung-based company said. “We do see the disparity between AI and other general sectors, and that pretty much aligns the scenario in the first half of this year,” ASE chief operating officer Tien Wu (吳田玉) told an
