Features and Attractiveness of the Plan
Harmony between the greenery of Atago-yama and the historical environment
The most distinctive feature of this redevelopment project is that the urban development will take advantage of the lush greenery and historical and cultural environment of Mt. Atago-yama is the highest mountain in the 23 wards of Tokyo in terms of natural terrain, and at its summit is the historic Atago Shrine, built in 1603 on the orders of Ieyasu Tokugawa. The redevelopment of the area is being undertaken in a manner that respects this precious natural environment and historical space and extends it into urban space.
Improvement of the approach to the shrine and creation of a plaza
A plaza will be created on both sides of the approach to Atago Shrine in continuity with the approach to the shrine, creating a dignified space that takes into consideration the historical nature of the area. Commercial functions will be provided on the lower floors of the building to create a lively approach space that will serve as a place to stay. This will create a place for shrine visitors, local residents, and office workers to gather and interact.
Consideration for the view and building layout
By placing high-rise buildings in the 1st district and reducing the volume of buildings in the 2nd district, we aim to secure the view to Mt. Atago and the openness of the space at the top of Mt. Particular attention has been paid to the views from Atago Shita-dori Avenue and the summit of Mt. Nomura Real Estate Development Co.
Biodiversity-conscious greening plan
The green space facing the Mt. Atago cliff line will be greened in consideration of biodiversity in response to the sloping forest on Mt. With the advice of experts, we aim to create an environment that will bring back the creatures that once inhabited this area.
Project Development Policy
Creation of an urban environment integrated with the greenery of Mt.
Create a plaza space that is continuous with the approach to Atago Shrine, creating a dignified streetscape that takes into consideration the historical nature of the area. By creating a greenbelt continuous with the sloping forest of Mt. Atago, a green network will be formed, creating an environment that also takes biodiversity into consideration.
Introduce residential functions appropriate for an international business and exchange center.
Taking advantage of its location in the natural environment of Mt. Atago and its proximity to hospitals, schools, and other facilities, we will introduce high-quality urban residential functions that are compatible with global standards. By taking into consideration the social trends of after-colonization, and by introducing lifestyle and industrial support facilities, we aim to realize a lifestyle of work and residence in close proximity to the natural environment of Atago-yama.
Infrastructure Improvement and Safety Measures
The approximate widening and improvement of Radiation Route No. 21 (Atago Shita-dori) will facilitate traffic and create a comfortable pedestrian space. In addition, we will underground electric cables along Ward Road No. 812, the approach to Atago Shrine (Ward Road No. 118), and roads within Mt. Atago to help ensure a safe and comfortable pedestrian space that contributes to strengthening the urban disaster prevention function.
As safety measures for the slope of Mt. Atago-yama, which has been designated as a special landslide disaster prevention area, we will reinforce existing retaining walls and slope reinforcement, while giving consideration to the preservation of greenery. Instead of using conventional construction methods, a method using wire nets and anchor piles was adopted after plotting trees one by one on a drawing and confirming even their health, in order to achieve both green preservation and safety.

Surrounding Environment and Location Attractiveness
Transportation Access
The nearest stations are Kamiyacho Station on the Tokyo Metro Hibiya Line and Toranomon Hills Station on the Tokyo Metro Ginza Line, both about a 7-8 minute walk away. Located in the heart of the city center, the location is convenient to anywhere in Tokyo.
Redevelopment Trends in the Surrounding Area
In addition to the redevelopment of Atago Green Hills, Toranomon Hills, and Toranomon Hills Residential Tower, which have already been completed, many other redevelopment projects are underway in the Atago area, including the development of the former Tokyo Toranomon Tokyu REI Hotel site and the Toranomon-Azabudai Project (Azabudai Hills) by Mori Building Co. In June 2024, the Kamiyacho area is scheduled to be completed as a new residential area.
In June 2024, construction will be completed on City Tower Toranomon, Sumitomo Realty & Development's luxury condominium for sale and rent, a two-minute walk from Kamiyacho Station, and in October 2025, Azabudai Hills Residence B is scheduled for completion. These redevelopments are increasing the value of the entire area.
Internationality and Living Environment
Kamiyacho area is a cosmopolitan international city with many embassies and foreign residents. The area has been designated as a special national strategic zone project and is being developed for the future as an international business center.
Attractiveness as a residence and asset value
Characteristics of Redevelopment Condominiums
The 41-story tower condominium to be built in the 1st district is a large-scale condominium with a total of approximately 360 units. The lower floors will house offices and stores, while the middle to upper floors will be residences.
Condominiums in the redevelopment area are attractive because the entire city block, including the sidewalks and plaza around the property, will be developed, making the streetscape beautiful and convenient. In particular, redevelopment properties with parks and commercial facilities in the area will guarantee a comfortable living environment.
Property Value Analysis
Prices of used condominiums in the Kamiyacho Station area have been on the rise in recent years, but the specific rate of increase in value depends on the property and the time of year. The fact that ARK Hills, Toranomon Hills, and Azabudai Hills, which have evolved through redevelopment, are within walking distance of the property, has also contributed to the increase in land value.
Depending on the floor and direction, this property offers views of Tokyo Tower and the lush greenery of Mt. Atago. The property is attracting a great deal of attention as a place where one can enjoy such an affluent living environment and asset value at the same time.
