“Roof Park Art Fes 2026” on the KK Line; Light by YOSHIROTTEN and Contemporary Circus

The Tokyo Metropolitan Government and Tokyo Expressway Co., Ltd. will hold “Roof Park Art Fes 2026” in the space atop the KK Line (the former Tokyo Expressway) for nine days, from Saturday, November 21 to Sunday, November 29, 2026. It is held only at night, from 17:00 to 20:30 (last entry 20:00). The main installation is by the artist YOSHIROTTEN, who expresses the memory of land where a river once flowed through light sculptures and other works. It is one of the highlight programs of “ARTE TOKYO,” a culture and arts festival that uses the city as its stage.

Turning the KK Line, no longer used as a road, into a place for people

The KK Line is a former expressway running through Kyobashi, Ginza, Shimbashi and other areas, distinguished by a structure in which the road sits on top of commercial buildings. Tokyo Expressway Co. is pursuing the “Roof Park Project,” which turns the space atop the KK Line, now that it has finished its role as a road, into a place people can enjoy. Its concept is “A future we build slowly, together,” and the aim is for the KK Line to connect the city like a “roof” and be open like a “park.” The English version of the official website gives the 2040s as the completion date.

The event is part of the Tokyo Metropolitan Government and the company’s efforts to revive the KK Line, and it is also positioned as an initiative promoting the “urban development and housing” and “greenery and water” strategies of the 2050 Tokyo Strategy. The creative director is Seiichi Saito, who is also general producer of ARTE TOKYO, and the spatial design is by architect Yuko Nagayama. On the KK Line, DESIGNART TOKYO 2026 also sets up its main venue, “AUTOBAHN,” from October 30 to November 3.

What works can be seen? YOSHIROTTEN’s four installations

The concept of the main installation is “INVISIBLE - A Signal of River -,” and its theme is “visualizing the invisible.” A large work of about 40 meters will also appear. The four works listed on the official website are as follows.

• “Orange Object X”: An orange object that receives signals from space appears on the former expressway

• “HALO”: A sculpture that converts the orbits of stars into light

• “SUN Installation”: An extension of “SUN,” a project that started from 365 images of the “sun,” creating a space to walk through while enveloped in color and light

• “INVISIBLE - A Signal of River -”: A giant sculpture emitting light signals expresses the memory of a place where a river once flowed. Past photographs and data are turned into video, and an orange luminous body floats in the night sky

YOSHIROTTEN is an artist who moves between fine art and commercial art and between the digital and the physical, and he heads the studio “YAR.” At TOKYO NODE in Toranomon Hills, his solo exhibition “YOSHIROTTEN: Communication with the Beyond / BEYOND EARTH” is also on view from October 30 to January 11, 2027 (our article on the exhibition). It is said to be the artist’s largest solo exhibition to date.

Contemporary circus tracing the memory of the Shiodome River

On Saturday, November 28 and Sunday, November 29, Setouchi Circus Factory will give a special performance. The piece, “SHIODOME SPACE-KK-RAFT,” is performed once each day; doors open at 18:30, and the performance starts at 19:00 and lasts about 50 minutes. The curve of the KK Line that serves as the stage follows the course of the Shiodome River, which once supported Tokyo’s logistics. Taking as its subject this river and the work of the people who transported timber, the piece is made up only of timber and the bodies of the circus artists and slowly moves along the elevated structure as it transforms into a spaceship.
