The Prudential Tower (プルデンシャルタワー) is a skyscraper located in Nagatachō, Chiyoda, Tokyo, Japan.

It is situated on the Sotobori-dōri trunk road, near the National Diet Building and other central government institutions, including the Prime Minister's Official Residence.

[1] Prior to and during World War II, the site was occupied by a luxury Japanese restaurant that was one of the command bases used by dissident military officers during the February 26 Incident in 1936.

Aiichirō Fujiyama's business conglomerate planned to build a luxury apartment complex on the site after the war, but the award of the 1964 Summer Olympics to Tokyo led to a "hotel boom" in the city.

Chiyoda itself entered bankruptcy in 2000, following which Prudential Life Insurance acquired the project and completed construction through cooperation with Mori Building.
