Major Achievements

Maritime traffic safety systems


e-Navigation is a system for the harmonious collection, combination, exchange, display and analysis, on ships and on land, of maritime information obtained by electronic means used for navigation and for the support of services related to the assurance of maritime safety and security and the protection of marine environments.

Offshore construction

During the rapid economic development of the 1960s, offshore public construction projects, such as the construction of ports and large-scale bridges, were carried out in order to develop infrastructures, including port facilities and roads.

Honshu-Shikoku Bridges/Tokyo Bay Aqua-line (Trans-Tokyo Bay Highway)/Tsurumi Tsubasa Bridge/Yokohama Bay Bridge/Hakucho Bridge/Tokyo Bay Rainbow Bridge Tunnel

Land reclamation

Large-scale offshore land reclamation projects were started in the late 1960s in order to develop land for the construction of ports and airports. We also have offshore land reclamation projects aimed at creating final disposal sites for household waste and debris generated by public construction, etc.

Reclamation at Osaka Nanko Port/Reclamation at Tatsumi and Shinonome, Tokyo/Reclamation at Wakasu, Tokyo/Tokyo Chuo Breakwater/Hibikinada Sea Area in Kyushu/Osaka Chuo Shinto Island/Minami-Honmoku/New Sea Surface Disposal Site (Shinkaimen Landfill Site)

Dredging projects

Modal shifts aimed at preventing global warming are being promoted. Modal shifts refer to the shifting from transportation by truck to transportation by ship and train. In order to support these modal shifts and to provide transportation by ship, national and local governments carry out navigation dredging projects aimed at maintaining the depth of water greater than the maximum draft of ships.

Major dredging projects: Nakayama Suido maintenance project/Bisan-Seto Inland Sea area dredging project

Electricity and energy business

Japan, which depends on the Middle East for the bulk of its energy sources, including fossil fuels, strives to ensure navigation safety for super-large oil tankers and LNG tankers, etc. Energy materials imported by ship are stored in national oil storage bases across Japan to be used by thermal power plants, factories and homes. In order to save energy consumption and reduce CO2 emissions, power generation facilities are working to use LNG as much as possible.

Major power stations: Tomari/Higashidori-mura/Onagawa/Kariwa/Tsuruga/Ikata/Genkai/Sendai/Yoshinoura/Maizuru/Date/Tachibana Bay/Futtsu
Major oil storage facilities: Kuji/Shirashima/Shibushi/Mutsu-Ogawara/Kushikino/Kamigoto/ Hokkaido Joint Storage
Major LNG storage facilities: Sakaide/Sakai/Himeji

Offshore Airport

Airports for welcoming tourists, airports for receiving imports and international hub airports that are open 24 hours a day—there is an ever-increasing demand for airports. At the same time, however, airports always have noise problems, and because of these problems, more and more airports are constructed offshore. Various construction methods are being developed, such as land reclamation with earth and sand and construction using floating bodies made of steel. However, no matter what construction methods are used, navigation beacons always play an essential role in providing safety to navigating ships.

Major airports: Haneda (second period)/Haneda (re-expanded)/Chubu Airport/Kansai (second period)/Kobe Airport/Tokushima Airport/Ube Airport/Okinawa Airport/Kitakyusyu (North Kyushu) Airport
