On Thursday, June 19, 2025, a celebration was organized in the Common Exhibition Area at the EXPO 2025 World Expo Osaka in Cammons C to mark the visit of the millionth visitor.

On this occasion, all the pavilions of the countries located in Commons C, which, in addition to the Republic of Croatia, also included Gabon, Guatemala, Israel, Montenegro, Panama, San Marino, Slovakia, Slovenia, Ukraine, and Uruguay, jointly organized a celebration of the awarding of the millionth visitor award.
Visitors and children could enjoy an organized fun quiz and creative workshop, which allowed them to learn more about some of the specificities of each country. The winners of the quiz received a special gift box with souvenirs from all 11 countries.

This event, in addition to presenting the heritage, customs, culture, and history —namely, the unique features and characteristics of the Republic of Croatia, as well as all other countries in Commons C —also demonstrated to all visitors the excellent mutual cooperation between countries and the unity in organizing such events.
