Kakyoin Square, Modern skyscraper in Sendai, Japan.

Kakyoin Square is a contemporary skyscraper in Sendai with 23 floors rising to approximately 106 meters. The structure combines office spaces with convenient access to local transportation networks and is an integral part of the city's commercial landscape.

The building was constructed between 1997 and 1999 under the development and design leadership of Mitsubishi Estate Company. This project marked an important addition to Sendai's commercial architecture during the late 1990s urban expansion.

The design theme is "the power of nature": the walls carry trunk motifs and the rooftop decorations evoke blossoming flowers. In front of the entrance lies Sendai's urban green space Kakyoin Green Area, 0.2354 hectares. The 20th and 21st floors once housed the headquarters of Digital Tu-Ka Tohoku, later J-Phone Tohoku.

Kakyoin Square stands at the southeast corner of the Kakyoin intersection, where Ekimae-dori meets Kakyoin-dori in Sendai's Aoba ward. It is about a 5-minute walk from JR Sendai Station and about 6 minutes from Sendai subway station on the Namboku line. A car park holds 185 vehicles. The Kakyoin Green Area (0.2354 ha) lies directly in front of the entrance.
