Bulgaria’s Yogurt Legacy Blossoms at Osaka Expo with Lacto-chan and a Microscopic Journey

Osaka Expo

Osaka, The Gulf Observer: Over five decades after first introducing yogurt to Japan at the 1970 World Expo in Osaka, Bulgaria returns with a pavilion steeped in both nostalgia and innovation, centered around one of its most iconic contributions to global health: Lactobacillus bulgaricus.

At the heart of the pavilion is Lacto-chan, a charming mascot modeled on the essential yogurt-making bacterium. With her cheerful persona and scientifically inspired design, she guides visitors through an engaging exploration of gut health, sustainability, and symbiosis with nature.

A Pavilion Where Science Meets Storytelling

Under the theme “Evolving with nature to save lives and shape a sustainable world,” Bulgaria’s pavilion serves as an immersive fusion of culture, microbiology, and ecological vision. From interior decorations that evoke the visual beauty of intestinal flora to high-tech interactive zones, the experience invites both awe and introspection.

Visitors are offered:

  • Immersive exhibits that scale down to the microscopic world of bacteria.
  • Sensory environments simulating natural landscapes and human biology.
  • Educational journeys highlighting how probiotics like Lactobacillus bulgaricus contribute to health and longevity.

More Than Yogurt: A Vision for the Future

This celebration of Bulgaria’s fermented food heritage is more than a nostalgic nod. It embodies a global call to reconnect with nature—on both a macro and micro level—and explore sustainable health solutions rooted in ancient wisdom and modern science.

By combining science communication with cultural storytelling, the pavilion not only honors Bulgaria’s yogurt legacy but also contributes to the global conversation on health, ecology, and innovation.

And with Lacto-chan leading the way, even the smallest microbe gets its moment to shine on the world stage.
