The 2025 Osaka Expo marked its national day for Japan on Thursday with a celebration of the host country's culture — from the contemporary to the ancient — in a ceremony featuring a spirited calligraphy presentation and a gagaku performance followed by a parade featuring Myaku-Myaku and Hello Kitty.

Still, there’s little doubt who stole the show.

Best-selling singer Misia thrilled dignitaries and members of the public alike as her powerful voice echoed throughout the expo’s Shining Hat venue during the ceremony’s feature performance.
