The International Association of Horticultural Producers (AIPH) members consist of thousands of growers of flowers and ornamental plants around the world who are together united by one essential goal – promoting the place of plants in people’s lives.
AIPH is responsible for approving the world’s most exceptional horticultural expos creating long lasting green legacies in cities across the globe.

With one year to go until opening, preparations for GREEN×EXPO 2027 Yokohama are entering a decisive phase, with the International Association of Horticultural Producers’ (AIPH) latest site inspection confirming steady progress across construction, planting, and international participation.
Taking place from 19 March to 26 September 2027, the AIPH-Approved A1 International Horticultural Exhibition will transform a 100-hectare site at Kamiseya, just 30 km from Tokyo, into a landscape-led Expo shaped by plants, production systems, and ecological design. Once a military communications facility, the site is being reimagined as a green, public-facing environment that retains its existing topography and mature trees.
For the horticulture industry, the direction of Yokohama 2027 signals a continued shift in how international Expos are conceived. Rather than focusing solely on display, the event is structured around living systems, with planting, cultivation, and landscape management forming an integral part of the visitor experience.
The site will be organised into distinct zones, including Urban GX Village, Craft Village, Kids Village, Farm & Food Village, and SATOYAMA Village. Each explores a different relationship among people, plants, and place, with particular emphasis on production, regional landscapes, and cultural practices associated with horticulture.

In the Farm & Food and SATOYAMA zones, crops such as rice and wheat will be grown throughout the Expo period, offering a visible demonstration of seasonality, land use, and agricultural cycles. This integration of production into the exhibition environment reflects a broader move within the sector towards more transparent and educational storytelling around how plants are grown.
At the heart of the Expo is the theme “Scenery of the Future for Happiness”, underpinned by the concept that all life is connected, with plants at its core. This is expressed through both the Themed Pavilion and the Horticultural Pavilion, the latter focusing on the evolution of Japanese horticultural culture and its relevance for future production systems.

Design plays a central role in how these ideas are communicated. The masterplan is led by landscape architect Shiro Wakui, with architectural oversight from Kengo Kuma, whose approach prioritises natural materials, human scale, and a close relationship between built form and landscape. The result is intended to be a low-impact environment where planting, structure, and movement are closely integrated.
Sustainability is embedded throughout the project, particularly through the concept of “Green Circular Architecture”, which prioritises the reduction, reuse, and recycling of materials. This includes the planned reuse of structural elements from Expo 2025 Osaka, Kansai, Japan, reinforcing a growing focus on legacy and resource efficiency across international exhibitions.

AIPH’s inspection delegation, led by Vice President Jack Goossens and including Secretary General Tim Briercliffe, reviewed progress on site readiness, operational planning, and international engagement. Participation continues to build, with countries such as Qatar, the United States, and Italy already confirmed, alongside involvement from international organisations including ITTO, UN-Habitat, and UNU.
With an expected 15 million visitors, GREEN×EXPO 2027 Yokohama is positioned not only as a public event but also as a platform for the global horticulture industry to demonstrate how plants contribute to climate resilience, urban development, and human wellbeing.
As the countdown continues, Yokohama 2027 is shaping up to be an Expo where horticulture is not simply exhibited but actively experienced, offering growers, suppliers, and industry stakeholders a living showcase of how the sector is evolving in response to environmental and societal change, and how plants will shape the cities of the future.
