groove agent Inc. (Head Office: Minato-ku, Tokyo; President: Satoru Ebinuma), which provides one-stop services from purchasing existing homes to renovation design and construction, is pleased to announce that it has been selected as the No. 1 contractor-type company in the Tokyo Metropolitan Area in the "2025 Fiscal Year Certified R Housing Issuance Number Ranking" announced by the Renovation Council on June 19, 2026.

We also report that our President, Satoru Ebinuma, has been appointed as a director of the same council.

Our company will continue to strive for the widespread adoption of renovation quality standards (Certified R Housing) and lead the revitalization of the market, enabling consumers to choose existing homes with peace of mind.

Expansion of the "Existing Home + Renovation" Market Due to Soaring New Construction Costs and Our Company's Achievements

In recent years, with soaring new condominium prices and a decrease in supply in the Tokyo Metropolitan Area, the shift to the existing home market has become even more pronounced. As the number of concluded transactions for existing condominiums in the Tokyo Metropolitan Area reached an all-time high in fiscal year 2025, interest in the "construction quality" and "peace of mind in unseen areas" of renovations has also reached unprecedented levels. In this market environment, our company has achieved the following results, with our "contract-type renovation" that shapes each customer's ideal being recognized for its reliable construction quality and inspection system:

2025 Fiscal Year Certified R Housing Issuance Numbers (Contractor Type Division)

Tokyo Metropolitan Area: No. 1 (Issuance Numbers: 125)

*Ranking details and figures are calculated based on data announced by the Renovation Council (Source: https://prtimes.jp/main/html/rd/p/000000104.000008586.html).

What is "Certified R Housing"?

A unified standard for excellent renovations established by the Renovation Council. It is a "peace of mind quality standard" for consumers, which clears inspection standards for important, unseen infrastructure such as water supply and drainage pipes and electrical wiring, and for which a warranty is issued.

Regarding the Appointment of a Director to the Renovation Council

In addition to being selected for the top ranking, our President, Satoru Ebinuma, has been appointed as a director of the Renovation Council. Leveraging the expertise cultivated in the field, our company will contribute to the council's promotion of "unified standards for excellent renovations," the promotion of "energy-saving renovations (e.g., Eco Cube)" towards a decarbonized society, and the development of human resources for the entire industry.

Comments on Appointment as Director

I am deeply grateful for this honorable recognition as No. 1 in the Tokyo Metropolitan Area for contractor-type renovations, and I extend my sincere thanks to our customers who have trusted us over the years, as well as to all the craftspeople and staff who have sincerely dedicated themselves to the quality of each and every house.

In a market where the resale of purchased properties is mainstream, the issuance of so many Certified R Housing units through our "contract-type" approach, where we partner with our customers, is proof that our company's strength in "thorough construction quality in unseen areas" has been supported. With new construction prices soaring, renovations of existing homes are becoming the standard for choosing housing in Japan.

As a director of the Renovation Council, I will contribute to building a sound market where everyone can achieve "peace of mind and freedom beyond new construction," by eliminating "cheap and poor quality" not only within our company but also across the entire industry.

Further Strengthening "Peace of Mind" in Construction

Our company has always conducted thorough inspections and photo documentation of unseen pipes and structural components. With this ranking result and the appointment as director as a catalyst, we will further enhance our "visualization of construction" and our "backup system for peace of mind and safety" by ensuring high construction quality through our own unique inspection standards, while adhering to the standards for R Housing. Through these efforts, we will continue to provide sustainable housing where everyone can live with peace of mind, and as a "renovation company that lasts a lifetime," we will long support our customers' lives after handover.
