Thorough Process Inspections
To provide housing where people can live for a long time with peace of mind, the Takara Leben Group conducts stringent checks at the construction stage. We put efforts into ensuring thorough quality management, with our staff regularly visiting construction sites to inspect building structures and conduct checks within the construction process of hidden areas, foundations, and finishing.
Obtaining Housing Performance Evaluation Reports
Takara Leben obtains housing performance evaluation reports from third parties designated by the Minister of Land, Infrastructure, Transport and Tourism to provide customers with greater peace of mind regarding their residences. To obtain these reports, we acquire performance evaluations in each stage of design on topics including earthquake- and fire-resistance, degradation resistance, energy consumption, and ease of maintenance. Construction is performed while undergoing five or more on-site inspections, and it is necessary to pass a rigorous performance evaluation at the time of completion.
Earthquake- and Fire-Resistant Structures
Robust Earthquake-Resistant Structures
In the construction of condominiums, we improve earthquake resistance by adopting the most appropriate construction method for the characteristics of the subsoil and its capacity to support the foundation. This includes the use of pile foundations, where strong piles are directly driven into the ground to the supporting layer, spread footing foundations, which provide support directly using firm subsoil, and seismic isolators, which disperse earthquake energy and dampen extreme, long-period building swaying.
In the construction of detached housing, we adopt wood-frame construction, which affords a high degree of design freedom and flexibility when adding to or renovating a structure in the future, together with a panel construction method that offers high durability and safety as well as good earthquake and fire resistance. We also employ as a standard feature a mat foundation method whereby a steel-reinforced concrete slab is laid underneath the entire wood floor to support the building, establishing a strong foundation using a high earthquake resistance and high durability construction method.
Exceptional Fire-Resistant Structures and Soundproofing Performance
We use highly fireproof materials when constructing condominiums. Fire-resistant and soundproofing performance standards are stipulated by law, and the thickness of the concrete walls between our condominium units, which require a high level of fire resistance and soundproofing, is approximately 180 mm. Furthermore, fire-resistant and soundproofing construction is used for the piping within pipe spaces facing residents’ rooms.
Accident Prevention Measures
The Takara Leben Group is working to prevent occupational accidents at workplaces and construction sites.
Health and Safety Patrols
Nikko Takara Corporation, which is responsible for building construction, performs health and safety patrols at each construction site at least once each month to create safer worksites. In addition to confirming the implementation of health and safety management, such as monthly and daily inspections and the assignment of certified personnel, they also aim to foster a greater focus on safety through the use of safety briefings and the like.
Top management also conducts joint special patrols with partners once each quarter. In July 2020, special patrols were performed to confirm the status of on-site maintenance and implementation of accident-prevention measures at construction sites and to ensure that strict heatstroke prevention measures are implemented and promote a workplace culture that does not overlook disregard for danger.
During National Safety Week, an initiative of the Ministry of Health, Labour and Welfare whose goal is to promote voluntary occupational accidents in the industrial world, foster more widespread safety awareness, and firmly establish safety activities, Nikko Takara Corporation’s offices and worksites work closely together and enhance the company’s health and safety management activities such as its measures to prevent the three main types of accidents (toppling and falling accidents, crane and other construction machinery accidents, and collapse accidents). Before National Safety Week, the company’s executives, employees, and partners gather for a Safety Conference that promotes greater health and safety management. The Safety Conference was not held in fiscal 2020 to prevent the spread of COVID-19.

Selection of Optimal Structures and Equipment
We change specifications for each property—not just the interior designs such as floors, doors, and kitchen/bathroom, but also the internal structure of buildings such as double floors, double ceilings, and piping within pipe spaces—according to the land and customers living there to give the most fitting combination of structure and equipment.

Crisis Management Structures in Leben Community
Leben Community has established solid crisis management structures to protect the safe lives and peace of mind of condominium residents.
Remote monitoring systems promptly send notice to a security company via telephone lines in the event of any abnormality in condominium facilities. If necessary, security personnel respond immediately. Through its inspections and staff training, Leben Community has established a system for responding appropriately in the event of an elevator, firefighting equipment, or other emergency.
Responses to a Large-Scale Disaster
Following the occurrence of the Great East Japan Earthquake in March 2011, an emergency earthquake countermeasures headquarters was immediately established, and initial measures were promptly taken. During disaster recovery construction, we provided support from the perspectives of a management association, led by our commitment to speed, dependability, and sincerity and based on the expertise and skills we have developed through our equipment and repair experience.
Crisis Responses in Large Buildings
In fiscal 2020, Leben Community implemented COVID-19 infection prevention measures at large condominiums in each region based on its many years of experience.
At the Park City Mizonokuchi condominium in Kawasaki City, Kanagawa Prefecture, which has about 1,100 households, Leben Community cooperated with the management association, community association, and a disaster control center to implement systematic crisis response measures for conducting comprehensive infection prevention measures and preparing for the occurrence of infections. Specific measures included morning and afternoon disinfection of items that are frequently touched by residents, such as elevator buttons, handrails, intercom panels, and doorknobs, and other rigorous infection countermeasures. Leben Community also urged residents to take preventive measures within their individual residences (such as ensuring adequate ventilation and limiting going out for non-essential purposes) and to exercise caution while on the condominium grounds (such as wearing a mask, refraining from speaking while in elevators, and adopting trash disposal methods that reduce the risk of infection).
Leben Community encouraged residents to take appropriate action by providing easy access to information needed if they suspected they were infected or became infected. It also produced the Infection Prevention News, a newsletter compiling information on these infection prevention measures, and distributed it to residents. In addition to infection countermeasures, the newsletter contained contact information for public agencies, information about on-site specialized infectious disease clinics and nearby restaurants that provide takeout and delivery services, warnings about tax refund fraud, and more, providing wide ranging support for life during the COVID-19 pandemic.
Disaster Preparedness Drills
Leben Community supports the safety and peace of mind of all condominium resident communities. One representative example of that is the disaster preparedness drills we conduct in conjunction with management associations, especially in large condominiums. It is no easy matter for residents, including senior citizens and children, to properly use condominium firefighting equipment in the event of a fire, or to rapidly evacuate the condominium via its evacuation routes. In the disaster preparedness drills, residents experience not only evacuation from upper level floors via stairs, but also evacuation via ladder trucks, evacuation by breaking partition boards on balconies, and initial firefighting using fire extinguishers.
In fiscal 2020, we held briefings on emergency drinking water purification systems, attended inspections, and conducted other such programs while taking measures to avoid the 3Cs (closed spaces, crowded places, and close-contact settings) during the COVID-19 pandemic and reducing the scale by limiting the number of people. We will continue to conduct disaster preparedness drills tailored to the situations of specific condominiums and enhance the disaster responsiveness of communities.
Moriya Disaster Preparedness Event
The Takara Leben Group collaborates with condominium residents and members of the community in promoting activities that heighten the disaster preparedness of community members. In November 2019, we held an Escape Attraction® disaster preparedness event for the residents of Leben Moriya THE BRIDGE, Leben Moriya THE SQUARE, and the members of the Matsunami Nishi Neighborhood Association in Ibaraki Prefecture. This program, created as a new type of disaster preparedness training at the third UN World Conference on Disaster Risk Reduction in March 2015, differs from conventional evacuation drills. A large screen is used to create an immersive simulated disaster experience for participants, who collaborate with each other to complete an evacuation preparation mission and an evacuation mission, seeking to reach the safety gate by the time limit (escaping the disaster safely). On the day of the event, 120 participants enjoyed learning about disaster preparedness and the importance of working with each other.
