Formerly known as Japan Tower, La Pacific is the first link, along with the Kupka complex, in the Valmy district. Designed by a charismatic figure in Japanese architecture, Kisho Kurokawa, it symbolizes the rapprochement between France and Japan.

The building's slender arc shape, formed by two wings connected by a multi-story bridge, is inspired by traditional European architecture, while the curtain wall references Japanese style—a tea room and Japanese garden are also located on the 25th floor. The building features an opening, presented as the gateway to the Orient, and a footbridge, an abstract expression of the Japanese bridge, connecting it to the Kupka buildings.
The Pacific Tower is a remarkable construction that combines space and time savings thanks to “high-performance” concrete and the installation of facade cladding elements before the load-bearing wall is poured.

A student of Kenzo Tange, Kisho Kurokawa (1934–2007) was one of the most charismatic figures in post-war Japanese architecture. He founded his own firm in 1962 after participating in the creation of the Metabolist movement, which theorized organically inspired spatial architecture. This research is perfectly expressed in his most famous work: the Nagakin Capsule Tower in Tokyo. He thus moved towards a symbiosis between Japanese values and the potential of contemporary technology.

With a view to bringing France and Japan closer together, Kisho Kurokawa designed two works in La Défense: the Pacific and the bridge connecting it to the Kupka buildings, the Japan Bridge.
