Nippon Salvage Co

Facing challenges
and establish numerous trust

We were born in 1893 and are expert at sea.
We have faced numerous difficulties with 2 pillars, salvage and marine construction work.
We have no moment to lose to fight with every salvage service, and, adding to sophisticated technique and knowhow, we are unable to tackle this job without strong mission and passion.
In this way, we have rendered services to a number of vessels, cargo and environment.

And, availing ourselves of long cultivated technique and knowhow in salvage business,we have extended scope of activities in the field of marine construction.
In order to meet demand of client we have been positively engaging in laying of submarine power cable and communication cable as well as offshore developing projects.
Technical ability, passion and sense of mission are all required to obtain trust of clients.
We will continue evolving for them. Right now at this moment.
