The International Horticultural Expo 2027 is a major world horticultural exposition held in Yokohama, Japan, approved by the International Association of Horticultural Producers (AIPH). Japan's horticultural tradition is deep and distinctive — encompassing everything from ikebana flower arrangement to bonsai cultivation, traditional garden design, and modern landscape architecture — making Yokohama an exceptionally fitting host.
The expo runs from March to September 2027 at a site associated with Yokohama's naval heritage and will feature garden installations from participating nations alongside Japanese regional and thematic gardens. Yokohama has historically been Japan's gateway to the world and the expo reinforces the city's international character. Multi-month horticultural expos of this scale typically attract millions of visitors and serve as enduring investments in green urban infrastructure.
