Being held for the third time in Osaka, Japan, the 184-day World Expo’s site will be located in Yumeshima, an artificial island located on the waterfront in Osaka that offers visitors a view of the Seto Inland Sea. With a vast 1.55 square-kilometers of space, the venue’s main pavilion will be surrounded by water to the south and greenery to the west, connecting the Expo to the world through sea and sky.
