As of 16 October 2026, 16 countries from Asia have announced participation in GREEN×EXPO 2027, among them India, the Republic of Korea and China. The figure is based on the lists published by the GREEN×EXPO Association (formally the 2027 International Horticultural Expo Association, a public interest incorporated association) and Japan’s Ministry of Foreign Affairs. Both cover the countries and international organisations that have announced participation in the 2027 International Horticultural Expo (GREEN×EXPO 2027). Eight of the 16 have gone on to sign official participation contracts with the Association.
Countries with a signed contract
Eight Asian countries have signed an official participation contract with the GREEN×EXPO Association: Thailand, India, the Philippines, Nepal, Bhutan, the Republic of Korea, Malaysia and the Kyrgyz Republic; the dates are in each country’s entry. Thailand, India and the Philippines also have their own articles on this site.
Country-by-country status (16 countries in Asia)
The table below gives each country’s official participation contract status and the capital, population and languages from Japan’s Ministry of Foreign Affairs. Of the 16, exhibit plans have been announced for only three: Thailand, India and the Philippines, covered after the table. The other 13 have no exhibit information as of October 2026. Where a row says “Association announced” rather than “Signed”, the Association has announced the signing but not (or not yet) the signing date.

India’s exhibit is expected to draw on the country’s philosophy of interconnection between all life, with elements of yoga, to present its broad horticultural culture. For more, see our dedicated article, “GREEN×EXPO 2027: India”.
Thailand’s pavilion is expected to use taste, scent, sight and sound to introduce the country’s efforts toward a sustainable future, such as soil regeneration and community revitalisation. For more, see our dedicated article, “GREEN×EXPO 2027: Thailand”.
The Philippines’ exhibit theme is “Bukás: Gardens of the Bayanihan Spirit”. In Filipino, “bukás” means both “open” and “tomorrow”, and the word is meant to describe a country open to nature, innovation and cooperation. For more, see our dedicated article, “GREEN×EXPO 2027: The Philippines”.
Our take
The Asian line-up leans toward Southeast and South Asia. Visitors who saw Thailand’s and India’s pavilions at Expo 2025 Osaka, Kansai should enjoy comparing them with what the two countries show in Yokohama. Thailand is also due to host the next A1-class Horticultural Expo, in Korat in 2029, and its participation in Yokohama may partly be preparation for that. For 13 of the 16 countries, however, no exhibit plans have been announced, and we don’t yet know what they will exhibit.
