behind the stage: the challenges of the Portuguese pavilion in Osaka

On Projections faced the design, logistics and execution in real time of one of the most complex and immersive pavilions in the Expo 2025 they Osaka. This installation highlights how a fully integrated audiovisual system can shape a cultural narrative on a global stage..

Run the entire infrastructure audio, video and lighting (AVL) of the Portugal Pavilion at the Expo 2025 they Osaka It was much more than a technical job for On Projections, the company responsible for the audiovisual integration and the daily operation of the space. It was a complex installation that tested creativity, the adaptability and resilience of the team at all levels.

From the beginning, The project posed important logistical and cultural challenges. All equipment had to be purchased new in Portugal, tested and packaged for international shipping, and imported to Japan under very tight deadlines and strict customs protocols. The weather conditions at the construction site were harsh, with temperatures below zero, constant rains and strong winds that complicated the first phases of construction and required constant readjustments in schedules and assembly methods.

The multilingual and multicultural makeup of the team added an additional layer of complexity. Daily coordination involved Portuguese professionals, Japanese, Italians and Brazilians working side by side. The meetings were held in several languages, with simultaneous translation and real-time decisions to align all disciplines, from scenography and civil works to audiovisual integration.

Throughout the process, many technical and logistical challenges arose, typical of a project of this magnitude.. Faced with unforeseen events and integration problems, On Projeções took responsibility for ensuring that each system worked correctly. The team was not limited to its initial scope: adapted components, adjusted installation details and reacted on the ground to keep the project on track and at the expected level.

Beyond the technical field, the On Projeções team played a central role in solving transversal problems: coordinated with set designers, intervened in the face of structural obstacles and provided support for the production of live events and diplomatic receptions. Your ability to connect technical design, The deployment of content and execution in real time was key to the success of the pavilion.

The room 2, the immersive highlight of the tour, presented a particularly demanding challenge. The curved walls and low ceiling created a complex environment for projection.

On Projeções worked with a 3D simulation complete in Dataton Watchout, synchronizing 16 projectors Barco and lighting effects in a continuous underwater landscape. Integration of the AVL system into a tablet-operated interface allowed one person to control audio, lighting and video at the same time, significantly improving operational efficiency.

The team also had to adapt to local customs and regulations. In Japan, For example, Boots or shoes are not allowed inside the buildings.; On Projeções technicians carried out complex audiovisual installations in socks or barefoot, with temperatures close to zero.

The absence of public trash cans forced waste to be transported back to the accommodation, and dietary adjustments were required throughout the two-month stay. These small details helped strengthen the team's cultural understanding and professionalism..

During the six months of the project, On Projeções prioritized both human well-being and technical excellence. pocket warmers, hot drinks and shared moments outside of work helped keep our spirits up. Mutual support and constant communication were essential, especially during long days marked by multiple responsibilities, rehearsals and live events.

More than a sample of technical capacity, The Portugal pavilion represents how a fully integrated audiovisual system can shape a cultural narrative on a global stage. Its success underscores the AVL's critical role in translating complex ideas into shared public experiences., and positions the project as a reference for future international exhibitions.
