Businesses and Technologies

DAI-ICHI CUTTER’s strengths

A leading company in a growing market

Various social infrastructures developed along with the rapid economic growth have deteriorated in quality, durability, and endurance due to aging and other factors, and there is a growing need to repair and renovate these infrastructures.

In the midst of the shift from the "manufacturing" to the "renovation and renewal" era, DAI-ICHI CUTTER, as a leading company in the specialty construction industry, is diversifying its construction methods through M&A and expanding its business sites nationwide.Since its establishment, the company has steadily increased its business performance and is the only specialty construction company listed on the Tokyo Stock Exchange Prime Market.

Growing need for the repair and renovation of social infrastructures

The share of renewal (maintenance and repair work) in the overall construction market has been increasing since reaching the 20% level in FY2001, and it is expected to reach up to approx. 5.1 trillion yen in FY2023.

Nationwide coverage

Our Group is the only one of its kind to have a comprehensive nationwide presence, making us number one in the industry in terms of performance.

High revenue base

The Company's core revenue base is the cutting and drilling business, which plays an active role in the repair and maintenance of social infrastructure. Except one previous loss, operating profit margins have generally remained above 10%.
Sales in the construction industry are subject to seasonal fluctuations. We intend to standardize the fluctuations in performance by diversifying our businesses, such as entering the building maintenance business and the IT & office equipment reuse and recycling business in order to make a comprehensive contribution to a recycling-oriented society as well as to enhance our corporate value over the long term.
