Deutsch-Japanisches Center, Hotel, office and retail building in Düsseldorf, Germany

The Deutsch-Japanisches Center is a modernist hotel, office and retail complex on Immermannstraße, built 1972–1978 by Takenaka Europe and Hentrich, Petschnigg & Partner. Shops and offices ring an inner courtyard; a granite-clad gate set at 45 degrees to the street axis forms a multi-storey portal quoting a Japanese torii. The Clayton Hotel Düsseldorf, formerly Hotel Nikkō, occupies part of the complex.

The complex was designed and built between 1972 and 1978 by architectural firms Takenaka Europe and Hentrich, Petschnigg & Partner. Its construction reflected growing business connections between German and Japanese companies in Düsseldorf during that period.

The courtyard plaques commemorate Louis Kniffler, who served as Prussia's first consular official in Japan as vice-consul in Nagasaki from 1861 to 1865. The complex also carries Japanese naming: the hotel was long called Hotel Nikkō, after the Nikkō-Kanaya inn in the Japanese city of Nikkō.

The granite gate stands on Immermannstraße, tilted 45 degrees to the street axis, and is the landmark to look for when approaching from the surrounding Japantown streets. Shops and offices ring the inner courtyard, while the hotel entrance, Japanese restaurant and 11th-floor spa belong to the Clayton Hotel and are used by guests. The memorial plaques for Louis Kniffler are in the courtyard.

The granite-clad gate stands at 45 degrees to the street axis, a detail easy to miss when walking straight along Immermannstraße. It rises across several storeys to form a monumental portal and abstractly quotes a traditional Japanese torii. The building was called "colossal" when it went up.
