Japan is a founding member of the BIE, and the country has successfully organised five Expos under the auspices of the Organisation. In 1970, Osaka Prefecture hosted Asia’s first World Expo, attracting over 64 million visitors, making it the most visited Expo of the 20th century. Since then, Japan has organised a second World Expo in Aichi in 2005, two Specialised Expos – in Okinawa in 1975 and in Tsukuba in 1985 – as well as a Horticultural Expo in Osaka in 1990. In 2018, Japan was elected by BIE Member States to organise World Expo 2025 in Osaka.
