Tokyo Garden Terrace Kioicho is hosting Kioi Rose Week 2026 from May 15 (Friday) to June 14 (Sunday), 2026, bringing a full month of floral experiences to the Kioicho neighborhood of central Tokyo.
This year, flower artist Nicolai Bergmann has designed the key visual for the event and is collaborating on a flower installation in front of Akasaka Prince Classic House, a live demonstration, a signing session, and a hands-on workshop. The theme, "BEYOND THE ROSE. — Roses Blooming in Kioicho," explores the energy of roses and the wider world of experiences that radiate from them.

"Nicolai Bergmann Fukuyama Rose" Makes Its Tokyo Debut
A new rose variety called "Nicolai Bergmann Fukuyama Rose" was born in 2018 through a collaboration between Nicolai Bergmann — who serves as a PR ambassador for Fukuyama City in Hiroshima Prefecture — and the city itself. Rare and limited in production, this large-flowered variety blooms in a refined, soft lavender hue and carries a clear, distinctive fragrance. It will be displayed in the flower beds in front of Akasaka Prince Classic House, together with the "World Rose Convention Fukuyama 2025 Commemorative Rose" — marking its first showing in Tokyo.
