The International Biology Olympiad for high school students from around the world will be held for the first time in Japan in Tsukuba, Ibaraki Prefecture, from July 12 to 19.
The four participants from Japan are busy preparing for the event and have attended a training camp, aiming to win the country's first gold medal at the Olympiad.
"I hope the event will reverse the trend against science and help to promote science education," an education expert said.
