The Expo 2025 opened in Osaka on Sunday with more than 10,000 people singing Beethoven's Ninth Symphony to celebrate the start of the six-month event that Japan hopes will unite the world divided by tensions and wars.

Here is what to know about the Expo 2025 Osaka:

What is Expo 2025 Osaka about? The Osaka Expo is held at Yumeshima, which means "dream island," a reclaimed industrial waste burial site in the Osaka Bay, where participants from more than 160 countries, regions and organizations showcase their futuristic exhibits inside about 80 pavilions of unique architecture.

"Creating a future society for our lives" is the main theme. It is Osaka's second Expo after the hugely successful 1970 event that attracted 64 million visitors, a record until Shanghai in 2010.

Organizers expect 28 million visitors through mid-October, though ticket sales have been slow, with about 9 million sold in advance, short of an initial target of 14 million.

"It’s been 55 years since the last Expo in Osaka. I've been looking forward to it," said Daiki Chiba, who traveled from Sendai, about 900 kilometers (560 miles) northeast of Osaka.

Many visitors carried Myaku-Myaku mascots or wore clothes matching its colors — red, blue and white — to get in the mood.

What does it mean to hold Expo amid global tensions? The Expo comes only four years after Japan struggled to host the no-audience Tokyo Olympics during the coronavirus pandemic.

It opens in the wake of trade wars and fears of a global economic downturn sparked by US President Donald Trump's tariffs, the three-year Russian invasion of Ukraine and Middle East conflicts.

Prime Minister Shigeru Ishiba compared the global tensions to a "national crisis" and said that Trump's tariffs, especially the 25% duty on automobiles, would be a blow to all industries and Japan's economy.

Still, Japan wants to turn the pinch into a chance.

"I think the timing is actually quite fitting," said Sachiko Yoshimura, head of Expo 2025 global communications. "Holding the Expo now could eventually help to address the divisions in the world. ... I believe this Expo in Japan might actually lead to stronger international relationships and improvements."

What is the Grand Ring? The iconic ring, designed by architect Sou Fujimoto, is a lattice-like structure encircling the venue and recognized by the Guinness World Records as the largest wooden architecture. It is 20 meters (65 feet) high and has a 2-kilometer (1.2-mile) circumference.

The costly ring takes up more than 14% of the Expo's total spending of 235 billion yen ($1.64 billion) and has triggered public criticism.

The total cost nearly doubled from the initial estimate largely due to the weaker yen, causing construction delays. Several pavilions, including those of Nepal, India, Vietnam and Chile, were not ready for the opening.

The ring is supposed to be partially reusable, reflecting the theme of creating a sustainable future.

What are other highlights? Exhibits of cutting-edge technology, such as robots and flying cars, as well as pop culture like Hello Kitty and Gundam, are among the highlights.

"Pavilions all look amazing," said Laurel Sylvester from New Zealand, visiting with her husband and two children. Her family is interested in ocean sustainability and planned to visit the Blue Ocean Dome. She said the boys are "super excited to have their photo with the (big Gundam) robot and some of the interesting tech things that are going on."

A small artificial heart made from induced pluripotent stem cells, or iPS, demonstrated a heartbeat at a Japanese health care pavilion. At the Future of Life pavilion, visitors can interact with robots. A human washing machine that was a sensation at the 1970 expo returned with a high-tech makeover.

The US pavilion focuses on space travel. Its lunar stone from the Apollo 12 mission, a sensation at the 1970 expo, was back on display.

China, also highlighting space technology, exhibits soil samples from its lunar missions.

Carrying a "Not for sale" sign and decorated with its blue-and-yellow national flags, Ukraine attracted many visitors with a globe and other items carrying barcodes. By scanning them, visitors can see videos showing people's lives at war and their reconstruction effort.

Dymtro Liuyi, Ukrainian creative director, said his country's participation was undecided until December due to the war. The preparation was finished Sunday morning, he said, showing blue paint on his fingers.

What is Myaku-Myaku? With its blue face encircled by red balls, some of them eyeballs, the mysterious, smiley creature Myaku-Myaku welcomes visitors.

The imaginary creature was born from the fusion of cells and water in a small spring in the Kansai region, organizers say. The friendly but clumsy character can transform into various shapes and is good at finding a rainbow after the rain.

A rock climber who fell hundreds of feet descending a steep gully in Washington's North Cascades mountains survived the fall that killed his three companions, hiked to his car in the dark and then drove to a pay phone to call for help, authorities said Tuesday.

The surviving climber, Anton Tselykh, 38, extricated himself from a tangle of ropes, helmets and other equipment after the fall Saturday evening. Despite suffering internal bleeding and head trauma, Tselykh eventually, over at least a dozen hours, made the trek to the pay phone, Okanogan County Undersheriff Dave Yarnell said, according to The Associated Press.

The climbers who were killed were Vishnu Irigireddy, 48, Tim Nguyen, 63, Oleksander Martynenko, 36, Okanogan County Coroner Dave Rodriguez said.

Authorities haven't yet been able to interview the survivor, who is in a Seattle hospital, said Rodriguez, so much is still unknown of the fall and Tselykh's journey.

Falls like this leading to three deaths are extremely rare, said Cristina Woodworth, who leads the sheriff’s search and rescue team. Seven years ago, two climbers were killed in a fall on El Capitan at Yosemite National Park in California.

The group of four were scaling the Early Winters Spires, jagged peaks split by a cleft that is popular with climbers in the North Cascade Range, about 160 miles (257 kilometers) northeast of Seattle. Tselykh was hospitalized in Seattle.

The group of four met with disaster that night when the anchor used to secure their ropes was torn from the rock while they were descending, Rodriguez said. The anchor they were using, a metal spike called a piton, appeared to have been placed there by past climbers, he said.

They plummeted for about 200 feet (60 meters) into a slanted gulch and then tumbled another 200 feet before coming to rest, Yarnell said. Authorities believe the group had been ascending but turned around when they saw a storm approaching.

A three-person search and rescue team reached the site of the fall Sunday, Woodworth said. The team used coordinates from a device the climbers had been carrying, which had been shared by a friend of the men.

Once they found the site, they called in a helicopter to remove the bodies one at a time because of the rough terrain, Woodworth said.

On Monday, responders poured over the recovered equipment trying to decipher what caused the fall, Woodworth said. They found a piton — basically a small metal spike that is driven into rock cracks or ice and used as anchors by climbers — that was still clipped into the climbers' ropes.

“There’s no other reason it would be hooked onto the rope unless it pulled out of the rock,” said Rodriguez, the coroner, noting that pitons are typically stuck fast in the rock. Rodriguez added that when rappelling, all four men would not have be hanging from the one piton at the same time, but taking turns moving down the mountain.

Pitons are oftentimes left in walls. They can be there for years or even decades, and they may become less secure over time.

“It looked old and weathered, and the rest of their equipment looked newer, so we are making the assumption that it was an old piton,” Woodworth said.

Rock climbers secure themselves by ropes to anchors, such as pitons or other climbing equipment. The ropes are intended to arrest their fall if they should slip, and typically climbers use backup anchors, said Joshua Cole, a guide and co-owner of North Cascades Mountain Guides, who has been climbing in the area for about 20 years.

Generally, it would be unusual to rappel off a single piton, said Cole, adding that it is still unknown exactly what happened on the wall that night.

“We eventually, if possible, would like to get more information from surviving party,” Woodworth said.

The spires are a popular climbing spot. The route the climbers were taking, said Cole, was of moderate difficulty, and requires moving between ice, snow and rock.
But the conditions, the amount of ice versus rock for example, can change rapidly with the weather, he said, even week to week or day to day, changing the route's risks.
