Expo 2025 Panasonic Group Pavilion “The Land of NOMO” lighting to utilize hydrogen derived from zero-carbon electricity

We will hold a ‘light-up’ ceremony on March 1, with a magical display of lights and mist

Osaka, Japan, February 28, 2025 - Panasonic Holdings Corporation (Panasonic HD) will use electricity generated from hydrogen derived from zero-carbon electricity to create a nighttime light-up display at the Panasonic Group Pavilion “The Land of NOMO” during the Expo 2025 Osaka, Kansai, Japan (Expo 2025). On March 1, a light-up ceremony will be held, featuring a magical display of lights and mist on the pavilion's organdy-adorned facade.

The Panasonic Group, which is committed to the long-term environmental vision “Panasonic GREEN IMPACT,” will use recycled materials for construction and showcase technologies that contribute to solving global environmental issues at the Expo pavilion. Additionally, hydrogen derived from zero-carbon electricity will be used for the light-up display. Beyond the experience at the “The Land of NOMO” Pavilion, the Panasonic Group aims to provide opportunities to “Unlock” the imaginative power of each child, leveraging the outcomes of co-creation activities with children that have been ongoing since before the Expo's opening. These efforts will also be incorporated into the light-up display.

Every day during the exhibition, from sunset until the pavilion closes at 10 p.m., there will be a light-up display featuring more than 10 different patterns that combine various colors and movements, designed by Yuko Nagayama, the architect of the pavilion. Additionally, once a day, there will be a special light-up performance created by children.

Hydrogen derived from zero-carbon electricity generated by solar power during the day at the NTT Pavilion is supplied through underground pipelines, and power is generated by a 5 kW pure hydrogen fuel cell installed in the Panasonic Group Pavilion. The electricity required to light up the pavilion at night (2.8 kW) uses this zero-CO₂ emission electricity.

＜Workshop highlights＞

To provide an opportunities to “unlock” the imaginative power of children, Panasonic HD has been conducting co-creation activities with children and students, reflecting these efforts in the creation of the pavilion through the “NOMO no Co-Project” since before the Expo. As part of this initiative, a light and sound display created by students from National Institute of Technology, Yonago College (Yonago College) and elementary school children will be featured.
Students from Yonago College have developed a system using Panasonic Group's developing IoT lighting “ILLUMME” that allows even beginner elementary school students to easily create original pavilion lighting displays by programming on a Scratch-based platform.
Elementary school children who participated in the light programming workshop “NOMO to Hikari to Monogatari (NOMO and Light and Story)” used the aforementioned system to program light and sound displays to match the stories they created, which were themed around the pavilion.

The light-up display will be managed through Panasonic Group's cloud-based lighting technology “YOI-en,” creating a magical atmosphere with 75 full-color LED floodlights and audio equipment. Additionally, The “Silky Fine Mist*”, generated by seven sprayer units used to help mitigate daytime heat, will also be used as part of the nighttime display.

* Environmental sensors send local temperature, humidity, and wind/rain data to Obayashi Corporation's smart building platform “WELCS place.” Through an API-integrated cloud system, the optimal mist spray volume is automatically controlled. Obayashi Corporation Smart Building Platform WELCS place®

The Panasonic Group will continue to connect with children even after the Expo concludes through activities such as an online co-creation platform. This initiative, starting with the “Unlock” experience at the “The Land of NOMO” Pavilion will accelerate its efforts to make children’s future brighter and more promising.
