About Us

Greetings from the representative

Kashima Nada, which connects the vast ocean with eastern Japan, is a blessed area where the Kuroshio Current and the Oyashio Current meet, and where abundant fish are landed throughout the four seasons, even in Japan, a maritime nation surrounded by the sea. It has also been bustling as a key point of maritime traffic, with a constant stream of ocean-going ships, domestic ships, fishing boats, work boats, and other vessels. The strong waves that crash against the coastline, which stretches about 170 km, make it known as a difficult spot for ships to navigate.
 
Our company was founded in 1972 in this area, which is also a logistics hub for eastern Japan, under the name Mikuniya Salvage Co., Ltd. We focused on salvage services such as the salvage and removal of wrecked ships and the prevention of marine pollution. Using our specialized skills, we also undertook port construction and waterside work on rivers and lakes. With the guidance of many people, we have accumulated a wide range of experience and grown together with the development of Japan's seas and ports.
 
 
In 1996, to better utilize the experience we had gained through this specialized work, we changed our company name to "MIKUNIYA Construction Co., Ltd." and shifted our focus from salvage to marine construction. With offices throughout the Kanto and Tohoku regions, over 100 company-owned vessels, and over 30 in-house divers, we strive to train all employees to be "artisans of the water." As a company of craftsmen who "build the ocean" on and underwater throughout the country, and as a robust disaster prevention company that "protects the ocean" in the event of an unforeseen disaster, we strive to contribute to the local community and society as a whole. By practicing "pointing and calling," we prioritize "safety" and strive to provide "better products" to "all customers" on time and without waste. We appreciate your continued patronage.
 
"100 working boats and a group of sea craftsmen"
