Global Ambassador Team from Japan
In 2009, Board Members Dr. Gerard Putz and Jim Woodland traveled to Tokyo, Japan, to present Science Olympiad concepts to Japanese education officials from the Ministry of Education (MEXT) and the Japan Science and Technology Agency (JST) at "Science Agora." A partnership between Science Olympiad and JST was born, founded on a shared passion for making science competition fun and exciting for all students. In March 2026, JST hosted its 15th Annual Japan High School Science Championships (JHSSC), a competition styled after the US-based Science Olympiad. Each year, the Grand Prize for winning the JHSSC is a trip to the US to participate in the Science Olympiad National Tournament. As at the 2012–2025 National Tournaments, Japanese students will join American peers in activities, march in the Parade of States and participate as guests in selected Science Olympiad test, lab and build events. Please welcome our 2026 Global Ambassador Team, Okayama Prefectural Okayama Asahi Senior High School!
