Tokyo Garden Terrace Kioicho will hold "KIOI ILLUMINATION 2026 –Color me Happy–" from Thursday, November 12, 2026, to Sunday, February 28, 2027.

The Beauty of Viewing From Outside, the Surprise of Stepping Inside
Alongside the event, an experiential Christmas tree called "KIOI Xmas Tree," which visitors can enter, will be installed from Thursday, November 12, to Friday, December 25.
This year's Christmas tree is an evolution of last year's popular "Tower of Light" (光の塔). Rather than a tree to be viewed only from the outside, it lets visitors step inside and be surrounded by light and greenery. On the first day, a lighting ceremony will be held with model Harumi Sato (佐藤晴美) as the special guest, and musicians Keiko Sakuma (佐久間景子) and Dai Komatsu (小松大) will also perform.
The exterior is a refined design that harmonizes with the streetscape of Kioicho. Step inside, and a dreamlike space themed "a geometric garden of light and greenery" opens up. Overhead, tree roots spread as if floating in the air, and light extending from them illuminates the whole space.
Green plants, geometric forms, and sparkling light overlap, inviting visitors into a world different from everyday life. The tree also looks different by day and by night. During the day, geometric panels reflect natural light and create a colorful, fresh glow. At night, countless lights twinkle and the space changes into one completely different from the daytime. This year, Kioicho offers a different way to enjoy a Christmas tree than in the past.

About the "KIOI Xmas Tree"

From "Symbol" to "Experience (Immersive)"
"KIOI Xmas Tree" is an evolution of last year's popular "Tower of Light" (光の塔), a Christmas tree that offers both the beauty of its exterior and an experience inside its interior space.
Exterior
The tree is designed as a refined landmark that harmonizes with the urban landscape of Kioicho. Geometric forms combined with colorful light and greenery make it stand out in the city.
Interior
The main feature is a dome-shaped structure that visitors can actually enter. Crystals, warm-toned lamps, mirror balls, and more are arranged in multiple layers inside. Light and shadow pouring down from overhead envelop the 360-degree space, creating a dreamlike, immersive experience. A lighting program of about 5 minutes, in which the light changes gradually, is also planned.
Different Looks by Day and Night
During the day, geometric panels reflect natural light, creating a kaleidoscope-like space. At night, the whole dome is wrapped in light, and reflections from the crystals and mirror balls create a dreamlike world different from the daytime.
