AIPH representatives have returned from a successful site inspection of the International Horticultural Expo 2027 Yokohama, Japan, set to open in less than two years. The visit, conducted in early June 2025, marks a key milestone as preparations intensify for this major A1-class Expo, formally recognised by both AIPH and the Bureau International des Expositions (BIE).
Led by AIPH Vice President Mr Bill Hardy, the delegation included AIPH Chair of the Exhibitions Committee, Mr. YAMADA Takuhiro, Chair of the Ornamentals Production Committee, Mr Jack Goossens, Secretary General Mr Tim Briercliffe, and International Relations Manager Ms Elena Terekhova. They were welcomed by the Japan Association for the International Horticultural Expo 2027 and received detailed updates on the Expo’s operational strategy, site readiness, international recruitment, and communication initiatives.
Expo Vision and Thematic Direction
Expo 2027 Yokohama, branded to the public as GREEN×EXPO 2027, will take place from 19 March to 26 September 2027, under the theme “Scenery of the Future for Happiness”. This vision responds to global environmental challenges by proposing a practical and hopeful blueprint for how societies can live within planetary boundaries. With a strong focus on nature-based solutions and circular economy principles, it aims to be more than a showcase—it is envisioned as a platform for mindset transformation, where hands-on experiences spark lasting behavioural change.
This overarching mission is expressed through four interconnected sub-themes:
- Co-adaptation – Harmony with nature.
- Co-existence – Co-existence living through greenery and agriculture.
- Co-creation – Creation of new industries.
- Co-operation – Resolution through co-operation.
Together, these principles will shape the site’s design, programming, and exhibitions, inviting participants to explore how horticulture can drive meaningful change in our world.
Site Transformation and Exhibition Planning
During the inspection, AIPH delegates toured key areas under construction and reviewed plans for international pavilions and exhibition spaces. Located just 30 km from Tokyo, the 100-hectare Expo site at Kamiseya spans Asahi and Seya Ward. It is undergoing a dramatic transformation from a former military communications facility into a vibrant cultural and innovation district. Five thematic villages—Farm & Food, SATOYAMA, Urban GX, Craft, and Kids—will offer immersive experiences in horticulture, sustainability, and creative community-building.
The design direction is led by Mr Wakui Shiro, with architectural oversight by internationally renowned architect Mr Kengo Kuma, known for blending natural materials with harmonious forms. The result will be a low-impact, experiential landscape that champions ecological design and social dialogue.
Three major indoor exhibitions will enhance visitor engagement with the cultural and environmental relevance of horticulture. The Themed Pavilion explores the interconnectedness of life, including an installation visualising the root systems of a pine tree that survived the 2011 Great East Japan Earthquake. The Horticultural Pavilion reflects Japan’s botanical legacy, particularly from the Edo period. It features a reproduction of Hanayashiki Flower Park, a historic site that was first opened in 1853 for the viewing of seasonal flowers. Meanwhile, the National Government Exhibition—curated by Japan’s Ministry of Land, Infrastructure, Transport and Tourism (MLIT) and the Ministry of Agriculture, Forestry and Fisheries (MAFF)—will showcase innovations in green infrastructure and agriculture, featuring a Reiwa-era Japanese Garden. Named after Japan’s current imperial era, which began in 2019 with the accession of Emperor Naruhito, the garden reimagines traditional design for today’s environmental realities.
Positive Outlook from AIPH Delegates
During the two-day visit, AIPH delegates reviewed current progress and held constructive discussions with Expo organisers and senior Japanese officials. Reflecting on the inspection, AIPH Vice President Mr Bill Hardy said: “We were impressed by the clarity of the vision and the depth of preparation. The team in Yokohama is not only meeting the expectations of an A1 Expo—they are raising the bar. Expo 2027 Yokohama (GREENxEXPO 2027) will be a major moment for horticulture and its role in global sustainability.”
The inspection confirmed that the Expo is advancing in accordance with AIPH’s Regulations and is on track to meet all key benchmarks. With momentum building and a clear sustainability mission driving its development, Expo 2027 Yokohama (GREENxEXPO 2027) is poised to set new standards in international horticultural exhibitions.
The Japan Association for the International Horticultural Expo 2027 will present its progress report for Expo 2027 Yokohama (GREENxEXPO 2027) at the 77th AIPH Annual Congress in Belgium in September, where members and stakeholders will receive further updates on participation, partnerships, and preparations.
