Policy and Concept
Condominiums built all over Japan that supported the rapid growth after World War II have aged and are in need of reconstruction. In addition to aging of the building, residents of condominiums which were full of childrearing families are also aging and declining in number. Solitary death has been raised as a social issue and revitalization of a community that brings the residents together is necessary.
Tokyo Tatemono Group places long-term reconstruction and focus on the re-development business as an important strategy of the Residence Business in the mid-term management plan. We will contribute to revitalizing the local community by renewing the existing stock of condominiums and buildings as well as creating new values that match the coming generation at the same time.

Brillia Koganei Sakuracho Condominium Revitalization
Brillia Koganei Sakuracho completed in May 2016 was born rebuilding a Koganei apartment building located in the richly green area of Musashino.
The building had already passed more than the roughly 50-year mark upon the initial inspection for the revitalization of the condominium. The residents were getting older and the deterioration of the building was progressing. The decision to rebuild was made in 2013 by comprehensively comparing the functional improvements via large-scale repairs and reconstruction because the building had issues from the aspects of functionality and crime prevention, such as the lack of elevators and auto-locks. Thereafter, we directly confronted challenges, such as the review of business plans through skyrocketing building costs, and held ongoing talks with all of the residents. Approval of the exchange of equivalent rights* plan was granted in 2014 and the project was completed without any problems.
Mobility became easy with the installation of elevators after largely improving the residential functionality through rebuilding. The condominium also offered easier living for children and the elderly, such as heightened crime prevention performance by changing the layout of the residential buildings.
- *Exchange of equivalent rights: Exchange of sectional rights and site usage rights to rights in the new condominium and issuance of monetary payments. A consensus between residents is necessary because the appraised value between the old building differs from the new. The exchange of rights plan needs approval by the mayor of the local government.
POINTPoints of the Brillia Koganei Sakuracho Condominium Revitalization
- Comprehensive comparison to examine large-scale repairs versus reconstruction
- Dramatic improvement in residential performance through reconstruction
- Planting and provision of parks to achieve both a richly green environment and crime prevention

Initiatives in Brillia Tama New Town Condominium Redevelopment
Brillia Tama New Town, completed in October 2013, is a community that was brought new life after a history of approximately 40 years as Tama New Town Suwa 2-chome Housing through the reconstruction business. We have worked on the project for six years in cooperation with right holders and related parties since 2007. As a result, we realized a total of 1,249 housing units in 7 buildings while preserving green spaces and securing public open spaces.
As the deterioration of the aging condominium worsens, the reconstruction project for Brillia Tama New Town has evoked interest in the social significance of revitalizing the historic Tama New Town and has garnered great attention. This has not only been inspected by customer but also management associations of properties thinking about rebuilding as well as local governments.
The ratio of age composition before the reconstruction was weighted towards elderly but age composition became slightly younger as about 70% of those that newly purchased housing units were between the age groups of 20s to 40s. Today, events are continually planned such as summer festivals to further nurture a community with the participation of a number of people regardless of whether a new or previous resident.
POINTPoints of the Brillia Tama New Town
- Largest condominium reconstruction project in Japan (640 units to 1,249 units)
- Revitalization of the community by changing the resident structure
- Preservation of the living environment by preserving green spaces

TOPICSCondominiums and Housing Complexes in the Works
The rebuilding project underway with the Itohpia Hamarikyu management association in the Minato Ward of Tokyo was approved in October 2018. The property had aged in the 39 years since it was completed, and we found areas unfit for earthquake performance. Rebuilding a property that faces an arterial road is also clearly a social responsibility to ensure an emergency transportation route if a disaster strikes.
(Tentative) Kita-Aoyama 3-chome District Redevelopment Private Venture Project currently in development on the former Toei Aoyama Kitamachi Apartment grounds in Kita-Aoyama, Minato Ward, Tokyo began construction in March 2018 (joint venture). This project has taken the form of a mixed land area in the heart of the district by developing the lots created privately in stages through rebuilding of the decrepit Aoyama Kitamachi Apartments. We earned an approximately 70-year fixed term lease to the site to establish rental apartments, senior residences that include services, and shops which respond to a wide range of lifestyles. We also will create a roughly 3,500 m² forest area (green space) to revitalize the rich nature essential to Aoyama.
