We went to the Osaka World Expo! Each pavilion is an architectural gem, but the main building—the The Grand Ring—was breathtaking. It’s officially recognized by Guinness as the largest wooden structure in the world. I’d heard it was huge, but seeing it in person… it’s enormous! At night it lights up like a colosseum, and from the rooftop you can see both the Expo grounds and the ocean. We did have to walk a lot, but many visitors are already coming back for repeat visits. Such an unforgettable experience!
