OSAKA: The World Expo 2025 has officially opened its doors on Yumeshima Island in Osaka Bay, kicking off a six-month global celebration of sustainability, innovation, and the future of life on Earth.

With the focus keyphrase Osaka Expo 2025, this landmark event brings together 158 countries and regions under the theme Designing Future Society for Our Lives. Running until October 13, the expo expects to welcome a staggering 28.2 million visitors, with daily peaks of up to 220,000 attendees.

Despite delays in preparation, excitement is high. The centrepiece of the expo is the Grand Ring—a 2-kilometre circular wooden structure that has already earned a Guinness World Record as the largest of its kind. It surrounds the main pavilions, each showcasing bold ideas for building a sustainable world.

Osaka Expo 2025 kicks off with focus on sustainable future

Japan’s national pavilion is stealing the spotlight with a display of a “Mars rock” found in Antarctica in 2000. Meanwhile, the local government’s pavilion is drawing crowds with its cutting-edge health tech, including beating heart tissue grown from iPS cells—a scientific marvel offering a glimpse into the future of medicine.

This is Japan’s third time hosting a World Expo. The previous one in Aichi in 2005 was a major success, while Osaka’s 1970 event became a symbol of Japan’s economic rise. Organisers hope this year’s edition will bring a similar boost, with a projected economic impact of ¥2.92 trillion (around $20 billion).

The Osaka Expo 2025 isn’t just about exhibitions—it’s about creating a platform for global conversations on sustainability, health, technology, and the way forward for future generations.
