We successfully completed two unprecedented large-scale projects: the complete concrete replacement of a 4,000 m long base runway (1986) and installation of buried light fixtures on an airport runway (1987).This experience served as a stepping stone for DAI-ICHI CUTTER KOGYO for future business expansion.

Water jet business

Birth of a second business pillar that can handle “cutting,” “chipping,” “washing,” “peeling,” and “scraping”

July 2002 Started water jet works.

Preparations were underway from around 2022 to establish a new water jet installation unit.
Initially, most of the construction was done as work to prevent highway spalling, but after the Niigata Chuetsu Earthquake in 2004, we began repair work on railroad viaducts and entered the field of concrete chipping work around reinforcing bars.
Prior to the move to a new building in 2005, the Water Jet Division was spun off as an independent organization.

2003 June Sendai Office opened in Izumi Ward, Sendai City, Miyagi Prefecture.

Listing of shares

Listing of the first construction company specializing in cutting, one of our goals since inception

June 2004 Listed on JASDAQ (Securities code: 1716).

More than 30 years had passed since the company was founded, and a strong financial structure had been built. However, we decided to go public based on a belief that more stakeholders watching over us would ensure even more stable management.
Since there was no precedent for a construction company specializing in cutting to be listed, it was initially difficult to get securities companies to understand the business. However, we successfully listed on JASDAQ on June 10, 2004.

From 2005
Expansion overseas and entry to new fields

Participation in projects overseas

Becoming a company protecting social infrastructure worldwide

February 2005 First overseas work performed in Indonesia.

Bursting work was performed in Indonesia in 2005 as part of ODA (Official Development Assistance).
The project was to remove scoured bridge piers in a short time. However, we had to wait for six days at the site because the cargo was delayed due to the severely-disrupted customs clearance at that time. As a result, only the last section of the piers was done using bursters.
This would be the Company’s first project outside of Japan.
Since then, wall saw work was done in Nigeria in 2012, special core drilling work was done in Vietnam in 2016, and since 2017, large scale works in Kuwait have been performed in collaboration with Group companies with locally-produced machinery.

Establishment of a system at the new location

Consideration for noise issues in residential areas

August 2005 Head office relocated to 833 Hagisono, Chigasaki City, Kanagawa Prefecture.

The Company purchased the land and buildings of the former Matsushita Denso Co. Ltd., which housed a three story factory building and a five-story office building, and relocated to the current location (833 Hagisono, Chigasaki City), a dedicated factory district.
With the following purchase of the adjacent land and buildings in 2010, the current site area is approximately 16,500 square meters.
A parking lot and machine/materials storage area, which had previously been rented outside the property, were now established on the site.
Today, the site of the former head office at Yanagishima is a quiet residential area.

2007 September WALLCUTTING Co., Ltd. in Aichi Prefecture became a subsidiary.
2008 August Diamond Kiko., co.Ltd. in Fukuoka Prefecture became an affiliate company.
2009 July Hokuriku Office opened in Nishikan Ward, Niigata City, Niigata Prefecture.

Building maintenance business

The birth of a third business pillar backed by the strength of careful work and high-quality equipment

July 2009 Started building maintenance business.

When the water jet business started to take off, the search started for a third pillar to follow the diamond method and water jet method.
In April 2009, the Building Maintenance Division was established after studying drain pipe cleaning that receives orders regularly from cutting work sites.

2009 November Koumei Kouji in Ehime Prefecture became a subsidiary.

Entry into surface treatment field

Commercialization of the shot blasting method after repeated studies

December 2010 Constructions using shot blasting started.

Shot blasting was also used in decontamination work following the accident at TEPCO’s Fukushima Daiichi Nuclear Power Plant in March 2011.
Initially, high-pressure water washing was the primary method of decontamination. However, the cutting power of blasting was highly valued, as washing requires more wastewater treatment.

2010 July Shinshin Kogyo Co Ltd. was established in Okinawa Prefecture.
2013 December Osaka Branch Office opened in Naka Ward, Sakai City, Osaka.
2014 July Movable Trade Networks Co., Ltd. in Tokyo became a subsidiary.
2017 September Listing changed to the Second Section of the Tokyo Stock Exchange
2017 December Listing changed to the First Section of the Tokyo Stock Exchange.

Promotion of Mergers & Acquisitions

For further expansion of technology and services

July 2019 ASIRE Corporation of Kanagawa Prefecture became a subsidiary.

April 2020 UNIPEC Co.,Ltd. of Hyogo Prefecture became a subsidiary.

Since going public, we have actively engaged in M&A to diversify our construction methods.
Most recently, ASIRE, a long-established company with high technological capabilities in the water jet method, became a subsidiary, followed the next year's acquisition of UNIPEC, a company engaged in cleaning work for plant facilities.
This strengthens the core business of DAI-ICHI CUTTER’s core business, which consists of “cutting,” “chipping,” “washing,” “peeling,” and “scraping.”

Sales office renewal

Pursuit a comfortable working environment

December 2020 Sendai Office relocated.

May 2021 Tochigi Office relocated.

August 2021 Takasaki Office relocated.

June 2022 Mito Office relocated.

Since 2020, we are relocating and rebuilding our sales offices to serve as a foundation for further company growth against a backdrop of increased productivity and expansion of the intermediate treatment business.

We will continue to grow to become a company
that will be called first (dai-ichi) in the world and in the universe
to protect the safety and security of society.
