Time Out says
Established galleries Taka Ishii, Tomio Koyama and ShugoArts make up the three-storey Complex 665, along with the showroom of Broadbean, a modern furniture and design group, on the first floor. Tucked away from the hustle and bustle of Roppongi, the warehouse-like building stands out from its surroundings thanks to a distinctive white-spiral motif on its exterior. The galleries are spacious and so you'll find a wider variety of works here – not just in scope and topic but size as well – compared to other space-limited galleries in the neighbourhood. They have been known to exhibit floor-to-ceiling and wall-to-wall paintings as well as realistic life-size human sculptures.
