The Umeda 3-Chome Project is based on the idea of connection, bringing together old and new and strengthening urban vitality. The site includes Osaka's former Central Post Office and neighboring plots, carrying a century of postal history. Parts of the historic building were carefully preserved and relocated into the new tower's atrium, where the reconstructed facade connects the site's heritage with its future. The approximately 188-meter, 39-story tower combines a theater, hotel, offices and retail, creating activity throughout the day. These uses reinforce one another, with theater audiences supporting shops and office tenants supporting hotel demand. The tower's restrained contemporary massing steps inward at its upper levels, creating a layered silhouette that complements nearby towers such as Grand Front Osaka while establishing a distinctive Umeda landmark.
As a major station-integrated development in Kansai, the project provides a coordinated urban-service experience. Direct connections to JR Osaka Station include a basement passage to the new Umekita underground station, a ground-level public route beneath the elevated tracks, and a second-floor pedestrian bridge to the existing south station building. Travelers can enter retail or office spaces or transfer to other lines directly. Inside, KITTE Osaka occupies basement level one through level six, offering regional food and specialty products to office workers and visitors. On the western side of level six, the MBS theater provides more than 1,200 seats and advanced stage equipment for musicals and concerts. An international hotel on the upper floors offers approximately 400 rooms. Office floors have some of Kansai's largest typical floor plates, approximately 4,000 square meters, and high-specification building services suitable for major corporate headquarters. Dedicated amenities include restaurants with views, shared meeting facilities, landscaped roof gardens, a gym and sauna. Together, these functions integrate work, shopping, recreation and entertainment in a comprehensive urban destination beside Osaka Station.
The spatial plan connects transport infrastructure and urban space. Retail areas in the large podium follow a loop arrangement, with an open urban plaza at the site's southeast corner for events, markets and pedestrian gatherings. Continuous covered walkways and street seating create a comfortable setting beside the busy station. The Nishi-Umeda Garden Avenue underground passage connects to the station, while a ground-level route beneath the elevated tracks links to the Umekita Phase 2 development to the north. The lower six floors contain retail and theater spaces, organized around a three-story central atrium incorporating the historic post-office facade. Daylight from above highlights the contrast between original stonework and new steel structures, creating an engaging indoor streetscape. Offices and hotel spaces begin above level six. Their contemporary glass curtain wall, metal mullions and horizontal lines give the tower an upright, composed appearance.
Rendering of JP Tower Osaka: retail and theater spaces occupy the podium, with offices and a hotel above, combining historic and contemporary elements.Rounded tower corners and alternating light-colored metal panels and glazing respond to the preserved building's palette while giving the upper floors a lightweight, transparent character. Efficient air conditioning, smart LED lighting, green roofs and rainwater recycling support the planned LEED and highest-level CASBEE certifications. These spatial and facade strategies bring tradition, contemporary architecture, function and aesthetics together in a renewed landmark beside Osaka Station.
