Collaboration between global architects and interior designers

Exterior architectural design was created by German architect Christoph Ingenhoven (Ingenhoven architects); the new building has been designed to harmonize with the existing Toranomon Hills Mori Tower and act as an international business hub. Interior design of retail facilities and "ARCH" was created by Masamichi Katayama (Principal of Wonderwall); it incorporates modern elements while reflecting the history and traditions of the surrounding Toranomon area.

Public art that colors the city

Public art works by three flourishing Asian contemporary artists with global reputations are displayed at office entrances and other places.

  • Office Lobby: Mariko Mori "Cycloid V" 2018, Sculpture
    This work incorporates various ideas about science, nature and the universe; these include the eternal cycle of the universe where birth and death are repeated and the Buddhist belief in reincarnation. Cycloid is a generic term for a trajectory drawn by a point on the circumference of a circle as it rotates along a straight line. It seems to amplify the energy within the office entrance by absorbing the magnetic force of Toranomon, rising while rotating like a complex Möbius strip. Shining like a pearl, the work's finish also creates a lively feeling of eternal rotation.
  • Office Elevator Hall: Futo Akiyoshi "Naked Relations" 2013, 2014, 2016, 22 Paintings
    Displayed in three white elevator halls, this is a work where oil paint has been thinly applied on a transparent acrylic plate. In this painting, where the overlap of colors and the movement of the brush are visible, it seems that only vivid colors are floating in empty space. The painted colors portray the connection of everything, involving the surrounding air and invisible energy.
  • Entrance of Retail facilities: Tsang Kin-Wah "Blow If you Will Float In the Wind" 2020, Installation
    Toranomon was once on the outer moat of Edo Castle, one of the four gates bearing animals that guarded it; Toranomon's featured a white tiger. This artwork sits in the entrance of the business tower - a new gate. The pillar in the center of the space is the tree trunk, and the text flowing on the glass surface represents the branches, leaves and petals falling on the ground and dancing in the wind. The mirrored ceiling makes the tree seem like it reaches into the heavens. The words of monks and thinkers such as Matsuo Basho, Zhuang Zhou and Mumon Gensen have been taken apart, and texts studded with the fragments convey imperfect aesthetics, such as beautiful changes in the four seasons, personal encounters and partings.
