The Republic of India signed the official participation contract for GREEN×EXPO 2027 at the Embassy of India in Tokyo on 26 February 2026. The GREEN×EXPO Association (officially the 2027 International Horticultural Expo Association, a public interest incorporated association) announced the signing on 6 April 2026, the same day it announced Luxembourg’s. India is also on the list of participating countries and organisations that the Association had published as of 9 September 2026. The Yokohama expo’s theme is “Creating the Landscape of Tomorrow’s Happiness.”
Basic facts
The figures below come from the basic data published by Japan’s Ministry of Foreign Affairs (as of 4 September 2026).

MOFA describes India as a key partner sharing basic values such as democracy and the rule of law with Japan, and as central to realising a “Free and Open Indo-Pacific.” Summit-level visits have continued in both directions since diplomatic relations were established in 1952. Prime Minister Takaichi’s visit in July 2026 produced around 20 intergovernmental documents, among them one marking 75 years of Japan–India diplomatic ties.
Official exhibit information
According to the Association’s announcement, Secretary General Masato Kawamura of the GREEN×EXPO Association and Priya Ranjan signed the participation contract at the Embassy of India in Tokyo on 26 February 2026. Ranjan, Director of Horticulture at India’s Ministry of Agriculture and Farmers Welfare and Managing Director of the Indian Horticulture Society, was appointed as India’s Commissioner General of Section. Ambassador Kazuhiko Koshikawa, the Japanese Commissioner General of the Expo, countersigned the contract.
The Association describes the exhibit’s direction as drawing on an ancient philosophy that recognises the interconnection of all life and values harmonious coexistence between humans and the natural environment. The description also mentions elements of yoga, added to show the strength and breadth of India’s rich horticultural culture. The exhibit’s footprint and pavilion details had not been announced as of September 2026.
A cultural primer
On flowers and gardens, Incredible India, the Indian government’s official tourism site, features “Amrit Udyan” (formerly known as the Mughal Gardens), inside Rashtrapati Bhavan, the President’s residence in Delhi. Architect Sir Edwin Lutyens and William R. Mustoe designed it in the 1920s and 1930s, following the capital’s move from Calcutta. The 15-acre garden follows the Persian-influenced “Char Bagh” four-quadrant layout: a Rectangular Garden with a central fountain, a Long Garden with a water channel, a Circular Garden, and a lower-level Sunken Garden. It is planted with roses, marigolds and dahlias, and includes a children’s garden called Bal Vatika, home to a 225-year-old Sheesham tree.
The same site presents yoga, Ayurveda, meditation and naturopathy as experiences for travellers to India, which lines up with the “elements of yoga” the Association mentions for the exhibit. Other examples the site highlights include the Tulip Garden in Patnitop, Jammu and Kashmir, and Haridwar, known for its Ayurvedic medicine and wellness centres.
Our take
We think India’s exhibit will range widely, taking in traditions of daily life such as yoga and Ayurveda as well as garden design. Amrit Udyan blends Persian influence with Indian and British elements, and with that kind of garden history, we would expect more than a simple flower show. Both points are our own guesses and are not part of any official announcement.
