Clouds Gather over Japan’s Ambitious Osaka World Expo

One of the largest wooden structures ever built is taking shape in Osaka, but hopes that Expo 2025 will unite the world are being dogged by cost blowouts and a lack of public enthusiasm.

The imposing circular centerpiece will be crowned by a 20-metre-high (65-foot) sloping canopy, designed by top architect Sou Fujimoto, known as the "Grand Roof".

It has a circumference of a staggering two kilometers and 161 countries and territories will show off their trade opportunities and cultural attractions at pavilions within the vast latticed ring.

A crane hoisted a block of beams into place this week as organizers said construction was largely on schedule, one year before visitors will be welcomed.

Expo 2025 global PR director Sachiko Yoshimura maintained that global participants would be "united" by the event even though there are conflicts in Ukraine, Gaza and elsewhere.

Russia will not be among the participants at Expo 2025, which will run from April 13 to October 13.

"Of course, there are so many crises around the world, but we want everybody to actually get together and think about the future and sustainability," Yoshimura said.

It has also met a lukewarm response in Japan, where promotion is ramping up and the red-and-blue Expo 2025 mascot "Myaku-Myaku" -- billed by the official website as "a mysterious creature born from the unification of cells and water" -- is ever-present.

A recent Kyodo News survey found that 82 percent of Japanese companies, sponsors and others involved said "fostering domestic momentum" would be a challenge.

Ballooning budget

The construction budget has ballooned 27 percent from 2020 estimates to 235 billion yen ($1.5 billion) due to inflation and Japan's chronic worker shortage.

Some say the costs are also hard to justify when 6,300 people are still in evacuation centers and hotels after an earthquake on New Year's Day devastated parts of central Japan.

Fujimoto's "Grand Roof" alone has a price tag of 35 billion yen and has been slammed by opposition leader Kenta Izumi as "the world's most expensive parasol".

The "Grand Roof" and other structures are temporary, with no clear plan for them other than organizers saying they will be reused or recycled.

The site on an artificial island in Osaka Bay will be cleared after the Expo, with plans to build a resort there containing Japan's first casino.

Jun Takashina, deputy secretary general of the Japan Association for Osaka 2025, acknowledged budget and regulatory "struggles" among foreign participants but said organizers would help make sure the displays are ready in time.

Among the most hotly anticipated attractions are flying electric cars, which take off vertically, showcasing the event's technological and environmental aspirations.

But the vehicles -- subject to reams of regulations -- will be a "kind of experiment", Yoshimura said.

More than 1.2 million tickets have already been sold and organizers hope to attract 28.2 million visitors, including 3.5 million from abroad.

That would be four million more than the last World Fair in Dubai but pales in comparison to the 64 million people who attended the 1970 Expo in Osaka, a record until it was overtaken by Shanghai in 2010.

'Future like science fiction'

The first world fair to celebrate culture and industrial progress was held in London in 1851, with the Eiffel Tower built for the 1889 Paris World Fair.

Osaka academic Shinya Hashizume, a specialist in architecture history and town planning, said he was amazed as a 10-year-old when he saw a "future that looked like science fiction" at the 1970 Expo.

The first film in IMAX format was shown at that event and visitors could admire rocks brought back from the Moon.

"Those six months were extraordinary for Osaka. Simply put, the whole town was having a party," he said.

The advent of mass tourism and hyper-connected societies may have since lessened the attraction but some Osaka residents still think it's a good idea.

Kosuke Ito, a 36-year-old doctor, said it would "strengthen the economy".

However, Yuka Nakamura, 26, said she might be put off by adult entry fees ranging from 4,000 to 7,500 yen ($25 to $50) a day.

The world's main coffee-growing regions are roasting under additional days of climate change-driven heat every year, threatening harvests and contributing to higher prices, researchers said Wednesday.

An analysis found that there were 47 extra days of harmful heat per year on average in 25 countries representing nearly all global coffee production between 2021 and 2025, according to independent research group Climate Central.

Brazil, Vietnam, Colombia, Ethiopia and Indonesia -- which supply 75 percent of the world's coffee -- experienced on average 57 additional days of temperatures exceeding the threshold of 30C.

"Climate change is coming for our coffee. Nearly every major coffee-producing country is now experiencing more days of extreme heat that can harm coffee plants, reduce yields, and affect quality," said Kristina Dahl, Climate Central's vice president for science.

"In time, these impacts may ripple outward from farms to consumers, right into the quality and cost of your daily brew," Dahl said in a statement.

US tariffs on imports from Brazil, which supplies a third of coffee consumed in the United States, contributed to higher prices this past year, Climate Central said.

But extreme weather in the world's coffee-growing regions is "at least partly to blame" for the recent surge in prices, it added.

Coffee cultivation needs optimal temperatures and rainfall to thrive.

Temperatures above 30C are "extremely harmful" to arabica coffee plants and "suboptimal" for the robusta variety, Climate Central said. Those two plant species produce the majority of the global coffee supply.

For its analysis, Climate Central estimated how many days each year would have stayed below 30C in a world without carbon pollution but instead exceeded that level in reality -- revealing the number of hot days added by climate change.

The last three years have been the hottest on record, according to climate monitors.

A dog decided he would bid for an unlikely Olympic medal on Wednesday as he joined the women's cross country team free sprint in the Milan-Cortina Games.

The dog ran onto the piste in Tesero in northern Italy and gamely, even without skis, ran behind two of the competitors, Greece's Konstantina Charalampidou and Tena Hadzic of Croatia.

He crossed the finishing line, his moment of glory curtailed as he was collared by the organizers and led away -- his owner no doubt will have a bone to pick with him when they are reunited.

Long known for its olives and seaside charm, the southern Greek city of Kalamata has found itself in the spotlight thanks to a towering mural that reimagines legendary soprano Maria Callas as an allegory for the city itself.

The massive artwork on the side of a prominent building in the city center has been named 2025’s “Best Mural of the World” by Street Art Cities, a global platform celebrating street art.

Residents of Kalamata, approximately 240 kilometers (150 miles) southwest of Athens, cultivate the world-renowned olives, figs and grapes that feature prominently on the mural.

That was precisely the point.

Vassilis Papaefstathiou, deputy mayor of strategic planning and climate neutrality, explained Kalamata is one of the few Greek cities with the ambitious goal of becoming climate-neutral by 2030. He and other city leaders wanted a way to make abstract concepts, including sustainable development, agri-food initiatives, and local economic growth, more tangible for the city’s nearly 73,000 residents.

That’s how the idea of a massive mural in a public space was born.

“We wanted it to reflect a very clear and distinct message of what sustainable development means for a regional city such as Kalamata,” Papaefstathiou said. “We wanted to create an image that combines the humble products of the land, such as olives and olive oil — which, let’s be honest, are famous all over the world and have put Kalamata on the map — with the high-level art.”

“By bringing together what is very elevated with ... the humbleness of the land, our aim was to empower the people and, in doing so, strengthen their identity. We want them to be proud to be Kalamatians.”

Southern Greece has faced heatwaves, droughts and wildfires in recent years, all of which affect the olive groves on which the region’s economy is hugely dependent.

The image chosen to represent the city was Maria Callas, widely hailed as one of the greatest opera singers of the 20th century and revered in Greece as a national cultural symbol. She may have been born in New York to Greek immigrant parents, but her father came from a village south of Kalamata. For locals, she is one of their own.

This connection is also reflected in practice: the alumni association at Kalamata’s music school is named for Callas, and the cultural center houses an exhibition dedicated to her, which includes letters from her personal archive.

Artist Kleomenis Kostopoulos, 52, said the mural “is not actually called ‘Maria Callas,’ but ‘Kalamata’ and my attempt was to paint Kalamata (the city) allegorically.”

Rather than portraying a stylized image of the diva, Kostopoulos said he aimed for a more grounded and human depiction. He incorporated elements that connect the people to their land: tree branches — which he considers the above-ground extension of roots — birds native to the area, and the well-known agricultural products.

“The dress I create on Maria Callas in ‘Kalamata’ is essentially all of this, all of this bloom, all of this fruition,” he said. “The blessed land that Kalamata itself has ... is where all of these elements of nature come from.”

Creating the mural was no small feat. Kostopoulos said it took around two weeks of actual work spread over a month due to bad weather. He primarily used brushes but also incorporated spray paint and a cherry-picker to reach all edges of the massive wall.

Papaefstathiou, the deputy mayor, said the mural has become a focal point.

“We believe this mural has helped us significantly in many ways, including in strengthening the city’s promotion as a tourist destination,” he said.

Beyond tourism, the mural has sparked conversations about art in public spaces. More building owners in Kalamata have already expressed interest in hosting murals.

“All of us — residents, and I personally — feel immense pride,” said tourism educator Dimitra Kourmouli.

Kostopoulos said he hopes the award will have a wider impact on the art community and make public art more visible in Greece.

“We see that such modern interventions in public space bring tremendous cultural, social, educational and economic benefits to a place,” he said. “These are good springboards to start nice conversations that I hope someday will happen in our country, as well.”
