Sekisui Chemical Co., Ltd. Housing Company (President: Masahide Yoshida) will introduce the '100-Year Long-Term Support System' *1 for 'Sekisui Heim' owners to strengthen long-term support.
Overview of the '100-Year Long-Term Support System' (*1, 2, 3)
In Japan, against the backdrop of social issues such as the increase in vacant homes due to population decline and environmental problems, the importance of properly maintaining, managing, and extending the lifespan of existing housing stock is increasing. In the 'Basic Plan for Housing' approved by the Cabinet in March 2026, looking ahead to the 100-year life era, one of the goals set is to seamlessly and comprehensively promote the management, revitalization, utilization, and removal of housing from birth to end-of-life.
Since 2000, our company has introduced the '60-Year Long-Term Support System' (*2), continuously providing appropriate maintenance and lifestyle-stage renovations for housing upkeep. On the other hand, since the earliest 'Sekisui Heim' homes built will reach 60 years after handover in 2031, we believe initiatives are necessary to ensure residents can live safely and securely even after 60 years.
Therefore, in 2026, the milestone year of the 55th anniversary of our housing business, we will newly introduce the '100-Year Long-Term Support System' (*1) and fully commence offering this service from 2031. This service will target over 600,000 existing 'Sekisui Heim' units nationwide as well as newly built 'Sekisui Heim' homes, continuously conducting building diagnoses (*3) up to 100 years after handover.
Through the provision of this service, we will aim for proper maintenance, management, and value enhancement of homes, contributing to the formation of high-quality housing stock and the realization of a sustainable society.
Features of the '100-Year Long-Term Support System' (*1)
1. Free building diagnosis (*3) every 5 years even after 60 years from handover. Supporting daily peace of mind.
2. Proposing appropriate repair methods to ensure housing safety through diagnosis of degradation conditions.
■ Background and Aims of Introduction
Until now, our company has viewed the housing business not as a 'build and sell' flow model, but as a stock-type business where homes are maintained, managed, and utilized into the future. By launching the '60-Year Long-Term Support System' (*2) in 2000, we have advanced initiatives for owners to live comfortably for a long time.
Our housing business celebrates its 55th anniversary in 2026, and 5 years later in 2031, the earliest Sekisui Heim homes built will reach 60 years after handover. Furthermore, by 2040, the number of Sekisui Heim homes exceeding 60 years from handover is expected to surpass 30,000 units (*4), making long-term maintenance and management increasingly important.
In the 'Basic Plan for Housing' approved by the Cabinet in March 2026, amidst Japan's population decline, increasing vacant homes, and environmental issues, there is a demand for the seamless and comprehensive promotion of appropriate management, revitalization, utilization, and removal of housing from birth to end-of-life in the 100-year life era.
With this service, by strengthening support for Sekisui Heim owners past 60 years since handover, we will contribute to extending the period they can live safely, restraining the occurrence of abandoned vacant homes, and forming a high-quality stock-type society.

1. Free building diagnosis (*3) every 5 years even after 60 years from handover. Supporting daily peace of mind.
Our company provides a '60-Year Long-Term Support System' (*2), which includes three regular inspections free of charge up to the second year after handover of new buildings, and regular diagnoses every five years from the 5th to the 60th year.

Furthermore, various inquiries such as housing troubles are accepted at the customer center 24 hours a day, 365 days a year, and we provide information on housing care and useful tips via the web, supporting daily life.
