The United Nations Pavilion at Expo 2025 in Osaka Kansai opened a space for visitors to learn about the organization as it marks its 80th year. The pavilion includes a photography exhibition, "1 Day I Will," presented and exhibited by Otsha, that displays the hopes and dreams of children growing up in challenging environments, mostly affected by crisis or conflict. The photographer described the project as a display of those hopes and dreams and said it is presented at the UN Pavilion during Expo 2025 in Osaka Kansai, Japan.
