The special exhibition Mass Extinctions: The Big Five at the National Museum of Nature and Science in Ueno, Japan, invites visitors to explore the mysteries surrounding five major mass extinction events that have occurred over Earth's 4 billion-year history. Scheduled from November 1, 2025, to February 23, 2026, this exhibition brings together top researchers in paleontology and volcanology to present the latest findings on these pivotal moments in evolution.

Highlights include an impressive interactive display featuring a giant globe known as the Mass Extinction Sphere, showcasing the Big Five events, and a model that simulates volcanic activity linked to these extinctions. The exhibition will also feature unique specimens such as the first-ever display of a 6-meter-long Steller's sea cow fossil from Japan, alongside other rare items from the Denver Museum of Nature & Science. Moreover, insights gained from excavations in Morocco will reveal new understandings related to these extinction events. Overall, the exhibition promises to deepen appreciation and knowledge of our planet's biological history.
