About the project

The Imperial Hotel Tokyo New Main Building is the fourth-generation home of Japan's most storied grand hotel, facing Hibiya Park on the site the Imperial has occupied since 1890. Designed by Paris-based Atelier Tsuyoshi Tane Architects under the firm's "Archaeology of the Future" philosophy, the scheme revives Frank Lloyd Wright's vision of a "Jewel of the Orient," merging the low, ornamented structure of a palace that welcomes distinguished guests with a modern tower symbolizing progress. The 200-250 billion yen rebuild anchors the wider transformation of the Uchisaiwaicho district beside Hibiya, and is conceived to carry the hotel's century-spanning legacy of craftsmanship, ceremony, and hospitality into its next era. Tane joins a design lineage that includes Wright, Yuzuru Watanabe, and Teitaro Takahashi.
