Corporate philosophy

Marine transportation professionals, at the forefront of the logistics industry

The blue sea stretching as far as the eye can see, limitless clear skies, cargo ships plying in the offing and the sight of Yokohama on the opposite shore, these make up the environs of Tomijima Unyu In keeping with our motto of “Safety, reliability, and promptness”, we have been serving our customers since our founding more than half a century ago in 1948, by providing transportation for their advanced technologies to worldwide destinations.
In parallel with the high level of development of the Japanese economy, in recent years, the demands of society on the logistic industry have become diversified and sophisticated.
In order to respond to such demands, we have utilized our wide ranging experience and established what we call the ‘Tomijima Total Transportation System’, which is an efficient total transportation system that includes the transportation itself, packing for export, warehousing, customs clearance, and loading on board a ship, as well as provision for our clients of information on overseas users.
Furthermore, in an effort to preserve our rich environment to hand down to our next generation, we have been actively involved in research and development of technologies for environmental protection. One of the fruits of these activities was the introduction of our original ‘steel cases’, designed with the problem of deforestation in mind.
Looking forward to a brighter future, we are committed to continuing to play the vital role of transporting to the world the state-of-the-art technologies in which our country takes such great pride. We will continue to offer the best transportation system available while protecting the global environment.

Environmental initiatives

Global environmental protection is also our mission.

The sea is indispensable for international logistics.
It is our job at Tomishima Transport to carefully protect the sea without polluting it.
We will continue to talk with the earth and aim for an earth-friendly transportation system.

Original steel case

We were the first in the packing industry to introduce steel, and we manufacture our original steel cases at the Yokohama Logistics Center.
The CAD system enables accurate packaging design, so the steel material is not wasted.
By reducing the conventional wooden box packaging, we are also considering forest protection.
We are also working on CO2 reduction by researching new materials and packaging specifications and transporting barges.

Hybrid packing

Hybrid packaging is a packaging that makes the best use of the advantages of wood packaging and steel packaging. We are constantly taking on the challenge of researching new materials and packaging specifications that are not bound by the current framework.
In addition, research on new materials and packaging specifications and efforts to transport barges have led to CO2 reduction.
