Just a couple of days before the grand opening of the World Expo in Osaka, Japan, abnormal methane levels were detected on the event grounds. Efforts have been made to minimize potential risks and ensure visitor safety.
The organizers have acknowledged the issue, stating that methane gas concentrations were so high that there was a risk of ignition. The risk was uncovered during a test run for the exhibition opening in an underground trench for electrical equipment.
As a result, a safety zone has been established around the affected area, and the said trench is being ventilated. Moreover, the organizers have ordered more regular gas measurements and enhanced ventilation. It's been confirmed that visitors will not have access to this specific trench.
The Expo grounds, located on Yumeshima Island, were formerly used as a landfill. In 2024, a building under construction there caught fire due to a methane explosion caused by welding sparks.
The Expo 2025 is all set to commence on Sunday. For six months, around 160 countries and regions will be showcasing their innovations and cultures to the world under the theme "Designing the Future Society, Creating Tomorrow's Life."

For a closer look at the site's backstory and the implications of this situation, here are some insights:
- The primary cause of the methane buildup is the historical use of Yumeshima Island as a landfill. Organic waste tends to decompose and produce methane. The issue was identified during the final rehearsal for facility operations just before the Expo's scheduled opening on April 13, 2025.
- In the past, a similar incident of methane explosion occurred in March 2024, damaging infrastructure but leading to no injuries. This unfortunate event underscored the site's ongoing safety issues, prompting the implementation of regular gas monitoring and ventilation protocols.
- Measures to combat the issue include increased monitoring, improved ventilation, restricted access to sensitive areas, and physical barriers to prevent unauthorized access during the Expo.
- The ethylene oxide spike may impact the Expo 2025 experience and operations, with temporary restrictions or adjustments in certain areas or planned activities possible. Regardless, organizers are dedicated to guaranteeing visitor safety during the event's six-month duration.
- In light of the detected high levels of methane gas at the Osaka World Expo site, the organizers have implemented a comprehensive employment policy to ensure regular gas measurements and enhanced ventilation, focusing on minimizing risks and maintaining visitor safety.
- Given the methane spikes at the Expo 2025 site, the community policy now includes the establishment of safety zones around affected areas and the restriction of visitor access to specific trench locations, adding measures to prevent unauthorized access during the event.
- In view of the historical use of Yumeshima Island as a landfill, and the associated risk of methane buildup, the employment policy will emphasize proactive monitoring and safeguarding procedures, drawing lessons from the previous methane explosion incident in March 2024 to create a safer environment for the 2025 event.
