Representative Comment

At the "end of the line" as a manager

Tsuyoshi Kawamura, Representative Director, Monolith Corporation

For the past several years, I have been thinking more about "how to keep it alive" than about growing the business.

However, when looking to the future of the construction industry, there are many challenges that small and medium-sized enterprises cannot handle. Barriers that cannot be overcome by effort alone. In order to break through these barriers, we realized that we needed to "change the stage.

The members who launched the On-Site Co-Creation Organization are younger than I am, and their financial strength and knowledge are incomparable to mine. I was convinced that the future of the construction industry would surely open up through the combination of their strength and our knowledge of the field, and I made the choice to co-create on a new stage.

M&A is not the end, but the beginning of the future.
