Bulgaria returned with its own pavilion to EXPO 2025 in Osaka after a long hiatus, inspired by the success of 1970, when Bulgarian yogurt captivated Japan and gave rise to the “Bulgaria” brand. That connection inspired the “Evolving with Nature” concept, which pays tribute to bacterial collaboration as a model for sustainability and unity. Commissioned at the state level, the project was realized through over two years of joint work between Bulgarian and Japanese experts, who reinforced the friendship between the two countries and combined traditional craftsmanship with modern technologies. Preparations included the production of art installations and multimedia exhibits in Bulgaria, followed by complex logistics and assembly in Osaka. At the opening, visitors marveled at the cord façade, the impressive projections, and the interactive AI “Pay It Forward” platform. More than 80,000 people experienced the exhibition, and the project sparked national pride, strengthened collaborations
