Paro the furry seal cries softly while an elderly woman pets it. Pepper, a humanoid, waves while leading a group of senior citizens in exercises. The upright Tree guides a disabled man taking shaky steps, saying in a gentle feminine voice, “right, left, well done!”
Robots have the run of Tokyo’s Shin-tomi nursing home, which uses 20 different models to care for its residents. The Japanese government hopes it will be a model for harnessing the country’s robotics expertise to help cope with a swelling elderly population and dwindling workforce.
Allowing robots to help care for the elderly — a job typically seen as requiring a human touch — may be a jarring idea in the West. But many Japanese see them positively, largely because they are depicted in popular media as friendly and helpful.

“These robots are wonderful,” said 84-year-old Kazuko Yamada after the exercise session with SoftBank Robotics’s Pepper, which can carry on scripted dialogues. “More people live alone these days, and a robot can be a conversation partner for them. It will make life more fun.”
Plenty of obstacles may hinder a rapid proliferation of elder care robots: high costs, safety issues and doubts about how useful — and user-friendly — they will be.

Despite steps by Japan to allow foreign workers in for elder care, obstacles to employment in the sector, including exams in Japanese, remain. As of the end of last year, only 18 foreigners held nursing care visas, a new category created in 2016.
But authorities and companies here are also eyeing a larger prize: a potentially lucrative export industry supplying robots to places such as Germany, China and Italy, which face similar demographic challenges now or in the near future.
“It’s an opportunity for us,” said Atsushi Yasuda, director of the robotic policy office at the Ministry of Economy, Trade and Industry or METI. “Other countries will follow the same trend.”
More than 100 foreign groups have visited Shin-tomi in the past year from countries including China, South Korea and the Netherlands.
A few products are trickling out as exports: Panasonic has started shipping its robotic bed, which transforms into a wheelchair, to Taiwan. Paro is used as a “therapy animal” in about 400 Danish senior homes.
STILL TINY
The global market for nursing care and disabled aid robots, made up of mostly Japanese manufacturers, is still tiny: just US$19.2 million in 2016, according to the International Federation of Robotics.
But METI estimates the domestic industry alone will grow to 400 billion yen (US$3.8 billion) by 2035, when a third of Japan’s population will be 65 or older.
“It’s potentially a huge market,” said George Leeson, director of the Oxford Institute of Population Aging. “Everyone is waking up to their aging populations. Clearly robotics is part of that package to address those needs.”
To nurture the industry, the government is using a two-pronged approach. METI is promoting development, providing 4.7 billion yen (US$45 million) in subsidies since 2015.
The labor ministry is spearheading the spread of robots, and spent 5.2 billion yen (US$50 million) to introduce them into 5,000 facilities nationwide in the year that ended last March. There is no government data about how many care facilities use robots.
Government officials stress that robots will not replace human caregivers.
“They can assist with power, mobility and monitoring. They can’t replace humans, but they can save time and labor,” said METI’s Yasuda. “If workers have more time, they can do other tasks.”
THAT’S A ROBOT?
Most of the devices look nothing like the popular image of a robot. By the government’s definition, each has three components — sensors, a processor and a motor or apparatus.
Panasonic used government aid to develop Resyone, a bed that splits in two, with one half transforming into a wheelchair.
Cyberdyne’s HAL — short for Hybrid Assistive Limb — lumbar type is a powered back support that helps caregivers lift people.
Those needing walking rehabilitation can grab hold of Tree, made by unlisted Reif, which crawls along the ground, showing where to place the next step and offering balance support.
SoftBank’s Pepper is used in about 500 Japanese elder care homes for games, exercise routines and rudimentary conversations.
But some workers find Pepper difficult to set up, said Shohei Fujiwara, a manager at SoftBank Robotics, a unit of Internet conglomerate SoftBank. They’d like Pepper to respond to voice commands and move around independently — functions that SoftBank hopes to introduce this year, he said.
A COSTLY SOLUTION
Cute, furry and responsive, Paro reacts to touch, speech and light by moving its head, blinking its eyes and playing recordings of Canadian harp seal cries.
“When I first petted it, it moved in such a cute way. It really seemed like it was alive,” giggled 79-year-old Saki Sakamoto, a Shin-tomi resident. “Once I touched it, I couldn’t let go.”
Paro took more than 10 years to develop and received about US$20 million in government support, said its inventor, Takanori Shibata, chief research scientist at the National Institute of Advanced Industrial Science and Technology. About 5,000 are in use globally, including 3,000 in Japan.
But Paro, like most robots, is expensive: 400,000 yen (US$3,800) in Japan and about 5,000 euros in Europe. Panasonic’s Resyone bed costs 900,000 yen (US$8,600) and Cyberdyne’s HAL lumbar exoskeleton costs 100,000 yen (US$950) a month to rent.
Most facilities using them, including Shin-tomi, have relied on local and central government subsidies to help cover the costs. Individuals can also use nursing care insurance to help cover approved products, but those numbers are tiny.
And so far, the robots have not reduced Shin-tomi’s personnel costs or working hours.
“We haven’t gotten that far yet,” said Kimiya Ishikawa, president and CEO of Silverwing Social Welfare, which runs Shin-tomi. “We brought them in mostly to improve the working environment, keep staffers from getting back injuries and make things safer.”
What they have done, he said, is boost the morale of both staff and residents.
“That’s brought a peace of mind among the staff and the residents feel supported,” he said.
As mega K-pop group BTS returns to the stage after a hiatus of more than three years, one major market is conspicuously missing from its 12-month world tour: China. The omission of one of the group’s biggest fan bases comes as no surprise. In fact, just the opposite would have been huge news. China has blocked most South Korean entertainment since 2016 under an unofficial ban that also restricts movies and the country’s popular TV dramas. For some Chinese, that means flying to Seoul to see their favorite groups perform — as many were expected to do for three shows opening
Taiwan’s semiconductor industry consumes electricity at rates that would strain most national grids. Taiwan Semiconductor Manufacturing Co (TSMC) alone accounted for more than 9 percent, or 2,590 megawatts (MW), of the nation’s power demand last year. The factories that produce chips for the world’s phones and servers run around the clock. They cannot tolerate blackouts. Yet Taiwan imports 97 percent of its energy, with liquefied natural gas reserves measured in days. Underground, Taiwan has options. Studies from National Taiwan University estimate recoverable geothermal resources at more than 33,000 MW. Current installed capacity stands below 10 MW. OBSTACLES Despite Taiwan’s significant geothermal potential, the
In our discussions of tourism in Taiwan we often criticize the government’s addiction to promoting food and shopping, while ignoring Taiwan’s underdeveloped trekking and adventure travel opportunities. This discussion, however, is decidedly land-focused. When was the last time a port entered into it? Last week I encountered journalist and travel writer Cameron Dueck, who had sailed to Taiwan in 2023-24, and was full of tales. Like everyone who visits, he and his partner Fiona Ching loved our island nation and had nothing but wonderful experiences on land. But he had little positive to say about the way Taiwan has organized its
The entire Li Zhenxiu (李貞秀) saga has been an ugly, complicated mess. Born in China’s Hunan Province, she moved to work in Shenzhen, where she met her future Taiwanese husband. Most accounts have her arriving in Taiwan and marrying somewhere between 1993 and 1999. She built a successful career in Taiwan in the tech industry before founding her own company. She also served in high-ranking positions on various environmentally-focused tech associations. She says she was inspired by the founding of the Taiwan People’s Party (TPP) in 2019 by Ko Wen-je (柯文哲), and began volunteering for the party soon after. Ko
