The new logo for the 2025 Expo was designed by a team led by graphic designer Tamotsu Shimada, who borrowed elements of the 1970 Expo and re-imagined them as chain of DNA. The ambiguous form and all its many cells are breathing, moving and dancing. It’s a design that will surely breath life into the Expo.

When the world’s first atomic weapon exploded in New Mexico in July 1945, the energy from the blast formed a new mineral called trinitite from the desert sand. For his 2015 Trinity Cube project, artist Trevor Paglen took irradiated glass gathered from the area around where the Fukushima Daiichi nuclear disaster occurred in 2011 and combined it with trinitite to form a blue cube. He then installed the cube in the Fukushima Exclusion Zone to continue to be irradiated.

The artwork will be viewable by the public when the Exclusion Zone opens again, anytime between 3 and 30,000 years from the present.
