Qatar was the first country from overseas to sign an official participation contract for GREEN×EXPO 2027 (the 2027 International Horticultural Expo). The GREEN×EXPO Association (the public interest incorporated association organising the expo) held a signing ceremony with Qatar on 13 May 2025 at the MAFF Sanbancho Conference Hall in Chiyoda, Tokyo. The signing made Qatar the expo’s first international exhibitor. Qatar also hosted the previous A1-class International Horticultural Expo, Expo 2023 Doha. The content of its exhibit became public with the implementation contract of 13 June 2026: a four-part pavilion based on a design by a Qatar University student. Information is current as of September 2026.

Official exhibit information
The GREEN×EXPO Association held the signing ceremony for the official participation contract on 13 May 2025 at the MAFF Sanbancho Conference Hall in Chiyoda, Tokyo. Ambassador Jaber Jaralla Al-Marri, Qatar’s Government Commissioner for its exhibition area, signed for Qatar. Association Secretary-General Masato Kawamura and Kazuhiko Koshikawa, Government Commissioner for the 2027 International Horticultural Expo, signed for Japan. In his remarks, Ambassador Al-Marri said Qatar was the first country to officially announce and sign its participation in the 2027 Expo, and stressed Qatar’s strong commitment to sustainability, innovation and cultural exchange.
With this signing, Qatar became the first country with an official participation contract for GREEN×EXPO 2027. Qatar hosted the previous A1-class International Horticultural Expo, Expo 2023 Doha, held from 2 October 2023 to 28 March 2024 under the theme “Green Desert, Better Environment.” The Japanese government (the Ministry of Agriculture, Forestry and Fisheries and the Ministry of Land, Infrastructure, Transport and Tourism) exhibited there and also promoted GREEN×EXPO 2027. Japan’s indoor exhibit won a gold award and its outdoor exhibit a bronze award. At the closing ceremony, the expo flags of the International Association of Horticultural Producers (AIPH) and the Bureau International des Expositions (BIE) were handed from Qatar to Japan as the next host.
Association Secretary-General Kawamura described Qatar’s exhibit as one that would “hand the baton symbolically from Doha to Yokohama.” BIE Secretary General Dimitri Kerkentzes and AIPH Secretary General Tim Briercliffe both sent comments welcoming Qatar, which successfully hosted Expo 2023 Doha, as the first country to sign a participation contract.
The pavilion, announced in June 2026
The specific content of Qatar’s exhibit in Yokohama became public the year after the signing ceremony. According to the Qatar News Agency (QNA), Ambassador Al-Marri and Jacopo Torini of Studio Dodici, the implementing company, signed the implementation contract on 13 June 2026. The contract covers the design, construction, operation, maintenance and dismantling of the pavilion. The pavilion follows the design “The Flourishing Fareej” by Qatar University student Aya Kambal Al Rayah, built around four sections, “The Beginning,” “The Roots,” “The Growth” and “The Bloom,” under the themes of sustainability, innovation, food security and urban development. Native Qatari plants and trees are to be woven into the visitor experience.
A cultural primer
The official site of Qatar Tourism (Visit Qatar) is a place to read up on those native plants. According to the site, Qatar is home to more than 300 species of wild plants, including desert roses. The site also describes green gardens and parks where visitors can picnic or exercise, and the Al Thakhira Reserve, home to Qatar’s oldest mangrove forest. Doha’s Education City has the Qur’anic Botanic Garden, the world’s only botanic garden dedicated to plants mentioned in the Qur’an. Supported by Qatar Foundation, it holds around 6,825 trees, shrubs and perennial herbs. These include annual plants such as mustard, cumin, barley, lentils, sesame, wheat and onion, and perennials such as saffron, aloe vera and basil.
On the food side, Visit Qatar describes machboos, rice cooked slowly with meat and spices, as Qatar’s national dish. It also highlights saloona, a tomato-based stew with cardamom, cloves, ginger and black lime, and luqaimat, sweet fried dumplings flavoured with cardamom and saffron.

Correction (19 September 2026): we had said the specific content of Qatar’s exhibit was unannounced; in fact the Qatar News Agency (QNA) had reported the signing of the implementation contract and the pavilion’s four-section design on 13 June 2026.
