The National Expo 2025 Memorial Botanical Garden, embraced by the world’s largest wooden structure, the Grand Roof Ring, will surpass London’s Kew Gardens in scale.
With seasonal blossoms, the Three Fragrances of wisteria, roses, and lilies, and the spectacle of Osaka’s Thousand Cherry Blossoms, it will become the world’s greatest botanical garden and a shared legacy for humanity.

The Grand Roof Ring, the architectural symbol of Expo 2025 Osaka–Kansai, is the largest wooden structure in human history and must be recognized as a National Treasure.
Encompassing this monumental creation, the National Expo 2025 Memorial Botanical Garden will surpass even the world-renowned Royal Botanic Gardens, Kew, in London in scale and layout, establishing itself as the world’s largest and finest botanical garden.

Unlike Tokyo, where greenery and forests have been relatively abundant, Osaka has long suffered from a lack of inner-city green space.
Now, with this project, the greatest “forest-as-garden” in history will arise in Osaka — a forest filled with seasonal blossoms and fragrances, a symbol of the future city, and a legacy to be shared by humanity.

🌸 Spring — A Festival in the Forest

• Plum Garden (Feb–Mar): White and red blossoms herald the arrival of spring.
• Cherry Blossom Garden (Mar–Apr):

  This breathtaking sight is the modern counterpart of Yoshino’s Thousand Cherry Blossoms.
  Seen from the Grand Roof Ring, “Osaka’s Thousand Cherry Blossoms” will stand as a reborn cultural symbol in the heart of the city.
