A-Tech and Kirii Manufacturing Forge Capital And Operational Partnership for Renovation Innovation

A-Tech and Kirii Manufacturing: Pioneering Renovation Solutions Through Partnership

In a significant development in the renovation industry, A-Tech Co., Ltd., a company specializing in comprehensive design and construction for apartment renovations, has announced a capital and operational partnership with Kirii Manufacturing Co., Ltd., a prominent building materials manufacturer. This collaboration aims to tackle procurement and logistics challenges in renovation projects, starting from the job site.

The two companies have identified a critical need for improvement in the procurement and logistics of building materials, traditionally reliant on outdated methods such as phone and fax communication. This reliance has often led to mistakes in order placements and difficulties in managing delivery schedules, thereby causing unnecessary burdens on both construction sites and material distribution channels. By joining forces, A-Tech and Kirii intend to leverage their expertise in renovation and material supply to enhance the speed and ease of building material procurement and logistics.

Background to the Partnership

The renovation market in Japan is experiencing substantial growth, estimated at approximately 7.3 trillion yen according to the 2025 Housing Renovation Market report by Yano Economic Research Institute. However, along with this growth comes the challenge of labor shortages, emphasizing the urgent need for enhanced productivity across the industry. A-Tech is acutely aware of these procurement and logistics challenges, gaining firsthand experience through its daily construction operations, while Kirii Manufacturing excels in manufacturing and supplying essential materials. This partnership signifies a strategic alignment aimed at addressing these challenges more effectively through shared insights and resources.

Overview of the Partnership

The partnership is structured as a capital and operational collaboration, which includes an investment from Kirii Manufacturing in A-Tech’s Series A funding round, the details of which remain undisclosed. Together, they will focus their combined efforts on solving the logistical hurdles faced in renovation projects. Specifically:

- Partnership Type: Capital and operational partnership (business collaboration plus investment from Kirii Manufacturing to A-Tech)
- Investment: Kirii Manufacturing’s investment in A-Tech during its Series A funding round
- Operational Focus: Joint initiatives to resolve building material procurement and logistics issues on renovation sites
- Role Division: A-Tech will implement solutions on-site, while Kirii Manufacturing will provide the necessary supply chain support.

To effectively tackle structural issues within material distribution, ongoing investments and deep collaboration will be crucial. Thus, both companies have committed to a long-term partnership beyond immediate collaboration, aiming for shared business and product innovations through their capital association.

Direction of Collaboration

The initial phase of their joint effort involves A-Tech testing a centralized digital solution for material ordering, delivery, and receipt at its renovation sites, under a project dubbed “kenzai cloud.” As of June 2026, they will initiate the first verification of this system in real renovation projects, assessing productivity improvements firsthand to ensure the solution's effectiveness and relevance.

Joint Exhibition at Renovation Industry Fair 2026

In a bid to share their partnership initiatives with the broader public, A-Tech and Kirii will co-exhibit at the Renovation Industry Fair 2026, which is scheduled for July 2026 at Tokyo Big Sight. The booth will highlight their partnership and the progress on the kenzai cloud project. Additionally, A-Tech CEO Yoshitaka Itazaka will speak at a seminar during the event, discussing why a renovation company would partner with a material manufacturer in a capital capacity, providing insights into the motivations and goals driving this collaboration.

Future Prospects

Both companies are committed to confirming and refining their processes within A-Tech's construction sites before extending their efforts towards addressing broader obstacles in renovation and material distribution. Concrete developments will be announced as they achieve significant milestones in their verification process.

Representative Comments

Yoshitaka Itazaka, CEO of A-Tech, expressed, "Having worked directly on renovation sites, I deeply understand the inconveniences surrounding material procurement and delivery. Collaborating with Kirii Manufacturing will allow us to initiate real change within our operations."

Takahiro Kirii, President of Kirii Manufacturing, added, "For us, having a partnership with A-Tech, who understands the realities of sites, marks a crucial step towards improving material distribution. We will leverage our combined strengths to enhance productivity in renovation projects."
