Japanese venture seeks to 'condense' hot springs for export
Mita's Tokyo-based venture firm, Le Furo, has invented a technology it calls "craft onsen" -- whereby hot spring ingredients are extracted and filtered into an ultra-high concentration.
Le Furo now seeks to use that patented technology to export Japan's hot springs overseas, with a view toward opening several onsen facilities in the Gulf region in 2026.
Transporting hot springs overseas long seemed logistically impossible because of the sheer volume of water involved, as well as their susceptibility to germs.
But with Le Furo's invention, "just like you extract coffee as espresso, we grind the mineral resources to fine, sand-like powders," CEO Naoki Mita told AFP.
The entrepreneur says many commercially available "onsen powders" are synthetic and put an emphasis on mimicking the relaxing colour and scent, and don't necessarily contain the necessary ingredients.
Only after solid metals such as iron, magnesium and zinc dissolve into water does it become possible to chemically resemble onsen and recreate the therapeutic effect, Mita said.
Le Furo's technology sticks to the natural soil and minerals of hot spring sources, and uses a special method to make them soluble in water.
Its "Craft Onsen" concentrate comes in bottles or small tanks, which can then be distributed and poured into water in other countries to feel like the real thing.
Onsens -- bath houses where patrons relax naked together in hot spring water of various temperatures -- are a major domestic industry in Japan beloved by both locals and tourists.
As of 2021, Japan was home to 28,000 confirmed hot spring sources, according to the environment ministry.
Le Furo is setting its sights particularly on countries like the UAE, Oman and Saudi Arabia where "water is considered a more precious resource than oil", Mita says.
"Here in Japan, we have this culture of soaking ourselves in a good, long bath to attain better health -- that's the kind of story that I believe (other countries) will show great interest in," Mita said. - AFP

Air Canada flight attendants walk off job, picket lines set up at airports
People hold placards as a strike begins after the union representing Air Canada's 10,000 flight attendants failed to reach an agreement with the airline, at Montreal-Pierre Elliott Trudeau International Airport in Dorval, Quebec, Canada August 16, 2025. REUTERS/Peter McCabe TORONTO/OTTAWA (Reuters) -Hundreds of Air Canada employees formed picket lines outside major Canadian airports on Saturday, hours after unionized flight attendants walked off the job in a contract dispute that has disrupted travel for tens of thousands of passengers. The strike, which started just before 1 a.m. EDT (0500 GMT), had forced Canada's largest airline to suspend the majority of its 700 daily flights, affecting more than 100,000 travelers who were forced to find alternative flights or stay put. As of Saturday morning, there were no bargaining sessions scheduled between the two sides, which have held on-and-off negotiations for months. The Canadian Union of Public Employees, representing more than 10,000 Air Canada flight attendants, confirmed the stoppage in a social media post. It is the first strike by Air Canada flight attendants since 1985. Outside Toronto Pearson International Airport - the country's busiest - hundreds of cabin crew waved flags, banners and picket signs. Union officials called on members to assemble outside all of the country's major airports, including in Toronto, Montreal, Calgary and Vancouver. Montreal-based Air Canada said the suspended flights included those operated by its budget arm, Air Canada Rouge. The stoppage would affect about 130,000 customers a day, the carrier said in a statement. Flights by Air Canada's regional affiliates - Air Canada Jazz and PAL Airlines - will operate as usual. "Air Canada is strongly advising affected customers not to go to the airport unless they have a confirmed ticket on an airline other than Air Canada or Air Canada Rouge," the airline said. WAGE DISPUTE The dispute between the union and the airline centers on wages. Attendants are currently paid only when their plane is moving. The union is seeking compensation for time spent on theground between flights and when helping passengers board. The union has said Air Canada offered to compensate flight attendants for some work that is now unpaid but only at 50% of their hourly rate. The carrier had offered a 38% increase in total compensation for flight attendants over four years, with a 25% raise in the first year, which the union said was insufficient. The impact of a strike will ripple far beyond Canada. Air Canada is the busiest foreign carrier servicing the U.S. by number of scheduled flights. While passengers have generally voiced support for the flight attendants on social media, Canadian businesses - already reeling from a trade dispute with the U.S. - have urged the federal government to impose binding arbitration on both sides, ending the strike. The Canada Labour Code gives Jobs Minister Patty Hajdu the right to ask the country's Industrial Relations Board to impose binding arbitration in the interests of protecting the economy. Air Canada has asked Prime Minister Mark Carney's minority Liberal government to act, but the union says it wants a negotiated solution, as binding arbitration would take pressure off the airline. Hajdu has repeatedly urged the two sides to return to the bargaining table. In a note to clients, analysts at financial services firm TD Cowen urged the carrier to "extend an olive branch to end the impasse," adding that investors are worried that any cost savings on labor would be outweighed by lost earnings in the airline's most important quarter. "We think it would be best for AC to achieve labor peace," the note said. "Not budging on negotiations risks being a Pyrrhic victory."

China's top diplomat Wang to visit India for border talks
Foreign Minister Wang Yi will visit India on Delhi's invitation from Monday (Aug 18) until Wednesday. - Photo: AP BEIJING (AFP): China's top diplomat will visit India next week for talks about their shared boundary, Beijing's foreign ministry said on Saturday, as the two countries consider resuming border trade after a five-year halt. Foreign Minister Wang Yi will visit India on Delhi's invitation from Monday (Aug 18) until Wednesday for "the 24th special representatives meeting on the China-India border issue", a spokesperson said in a statement. Past trade between the neighbours across icy, high-altitude Himalayan border passes was usually small in volume, but any resumption is significant for its symbolism. It stopped following a deadly 2020 clash between border troops. Indian media reported this week that Wang was expected for talks in New Delhi on Monday. He will meet Indian national security adviser Ajit Doval, New Delhi's foreign ministry confirmed in a statement on Saturday. Wang will also hold talks with his Indian counterpart Subrahmanyam Jaishankar, who visited Beijing in July, the statement said. The two major economic powers have long competed for strategic influence across South Asia. However, they have moved to mend ties after being caught up in global trade and geopolitical turbulence triggered by US President Donald Trump's tariff blitz. Chinese and Indian officials have said in recent weeks that the two countries were discussing the resumption of border trade. Agreements to resume direct flights and issue tourist visas have also been seen as part of an effort to rebuild their relationship. - AFP

Vietnamese rice grower helps tackle Cuba's food shortage
Vietnamese rice specialists watch mechanized rice harvesting, in Los Palacios, Pinar del Rio province, Cuba, on May 29, 2025. The Cuban government gave land to a private Vietnamese company for rice production in the face of the lack of local productive varieties and inputs to solve the lack of this cereal on the island. The national average rice yield is 1.6 tons per hectare, and the first fields harvested within this plan had a yield exceeding six tons per hectare. - Photo by Adalberto ROQUE / AFP LOS PALACIOS, Cuba (AFP): Outside Havana, a combine belonging to a private Vietnamese company is harvesting rice, directly farming Cuban land -- in a first -- to help address acute food shortages in the country. The Cuban government has granted Agri VAM, a subsidiary of Vietnam's Fujinuco Group, 1,000 hectares (2,470 acres) of arable land in Los Palacios, 118 kilometers (73 miles) west of the capital. Vietnam has advised Cuba on rice cultivation in the past but this is the first time a private firm has done the farming itself. The government approved the move after a 52 percent plunge in overall agricultural production between 2018 and 2023, according to data from the Center for the Study of the Cuban Economy at the University of Havana. The rice numbers are even worse. Total rice production dropped from 300,000 tons in 2018 to 55,000 tons in 2021, in the depths of the COVID pandemic. The number is slowly recovering, authorities say. Rice is a staple of the local diet, with Cubans consuming 60 kilos (132 pounds) of rice per person per year. Farmers load sun-dried bags of rice onto a truck, in Los Palacios, Pinar del Rio province, Cuba, on May 29, 2025. - AFP Photo - Promising yields and daunting obstacles - During a media visit to its rice fields in May, an Agri VAM representative said the harvest yield to date is seven tons per hectare, "but we want more." That number dwarfs the ton and a half yield-per-hectare of Cuban growers. Vietnam experienced the kind of food shortages that Cuba is going through now, in the 1980s. Today, the Southeast Asian country is the world's third exporter of rice and a valued consultant to other rice-growing nations. "The climate and the temperature are very good for agriculture," but Cuban growers lack necessary farming products such as fertilizers, the Agri VAM representative told reporters. Though Agri VAM can import some materials, it faces other obstacles such as fuel shortages, transportation problems and frozen assets, Cuban economist Omar Everleny Perez and other sources with knowledge of the situation told AFP. Agri VAM and other foreign firms in Cuba may be making profits but "they cannot transfer them abroad because the banks have no liquidity, no foreign currency," Perez said. An independent Cuban media outlet, 14ymedio, recently published excerpts of a letter dated in May, in which Agri VAM asked the Cuban government to unfreeze $300,000 in its account at state-owned International Financing Bank. Vietnam's state press in May quoted deputy agriculture minister Nguyen Quoc Tri asking the government in Havana "to eliminate investment barriers that Vietnamese companies encounter." AFP contacted Agri VAM and Cuban officials but got no response.

Vietnam and other allies have shown interest. In July, Cuban Prime Minister Manuel Marrero Cruz announced that Havana was taking measures "to energize foreign investment" as he authorized "wholly foreign-owned companies" in the hotel sector. After three years of promises, Russia's deputy prime minister Dmitry Chernyshenko announced in May that Russian businesses want to invest $1 billion in Cuba. Moscow will give them preferential financing rates, he said. But he cautioned that there is "still hard work to be done" and said it is "impossible to achieve things immediately, as if by magic." - AFP
