By creating two castles, which are seen as traditional symbols of strength and power, using cardboard and blue sheets, Makoto Aida questions the notion of permanence: "These reliable materials are robust but they also symbolize something temporary, which we often see in regions that have been affected by natural disasters in Japan," the artist says, stressing the need to withstand challenges.

"A tea house requires height; it brings a new perspective on the world. Once you climb up and enter through the narrow and dark entrance, you see a completely different scenery. This effect is unique to tea houses," says artist Terunobu Fujimrori, who is fascinated by the thoughts that go into building tea houses, which are a central part of traditional Japanese architecture.

On its first floor, the tea house opens to a view of the National Stadium designed by architect Kengo Kuma. The contrast between the traditional space reserved for tea ceremonies and the 21st century design of the stadium highlight the opposites that are central to contemporary Japanese culture: Can they coexist, as pandemics, natural disasters and changing social dynamics challenge tradition?

The theme of tea ceremonies continues at The Obliteration Room by artist Yayoi Kusama. But here, the focuses is on the aspect of (self)-destruction that is innate to repetitive rituals. This white room will soon disappear, as visitors will cover it with polka dots stickers in order to "obliterate" it. As the dots increase, everything disappears into them and "absorbed into something timeless."

This large-scale mural covering the glass wall of Marunouchi Building and New Marunouchi Building forms a pair of huge canvasses created by artists Tadanori Yokoo and Mimi Yokoo. It depicts the energy of two elements: water and fire: "This project contains the desire to transmit this energy, this big swell of universal life forms, from Tokyo to the world and the future," the artists explain.

Teppei Fujiwara created a "theater for plants and people," designed to act as an "urban forest" with a complex interplay of woodwork and plants. The Pavilion evokes a tradition that has been passed down from generation to generation since the Edo period, when people started to put plants pots in front of their houses. This legacy still continues in Tokyo today, creating spaces for people to rest.
