Japanese Senator Yoshio Yamashita has slammed expo organizers over safety failures after methane gas levels exceeding explosive limits were detected at the Osaka-Kansai Expo site. At a Senate hearing, the lawmaker called out what he labeled “illustrated promises” – pledges for rigorous safety measures that remain unfulfilled.
Methane Risk & Security Lapses
A Sept. 6 incident revealed methane concentrations beyond safety thresholds at Yumeshima Island – the expo’s future home. Despite evacuation drills and monitoring plans announced earlier, no fire safety protocols were activated, and security reportedly blocked access to emergency alerts.

Citing historic gas explosions in Osaka (1970) and Himeji (2010), Yamashita stressed that temporary fixes won’t suffice. His proposals include mandatory ventilation systems, 24/7 methane monitoring, and specialized staff training. Deputy Director Mogi of Japan’s Expo Promotion Office admitted safety efforts were “inadequate” and vowed upgrades.
With 18 months until the expo’s launch, the debate highlights rising pressure on Japan to balance global visibility and public safety. Will Osaka learn from past mistakes?
