Houseflags of Japanese shipping companies

Nippon Marine Co. Ltd., Tokyo, is a shipping company and agency offering a number of supplementary maritime services such as forwarding, crewing, maintenance, etc. It's English homepage is at http://www.nipponmarine.co.jp/e/index.html

In presenting this company grateful use is made of the President’s words (Mr Nobuyuki Kobayashi): quoting from the relevant "Outline of the Company" section:

Nippon Marine traces its origins back to a shipping company founded in 1900 by Enjiro Tatsuzawa. In 1923 the business was reorganized as a joint-stock company under the name of Maru-Raku Shipping. Over the following three-quarters of a century, the Company underwent a number of name changes, finally emerging as the Nippon Marine Co., Ltd. (...)

We carry cargo for a large number of customers, including the members of the Nippon Mining Holdings Group. The Company's shipping service covers not only cargo transport from one port to another in Japan, but also transport to and from ports in Southeast/East Asia. Moreover, one of our ships, the Cypria -- the world's first carrier dedicated to the transport of both copper ore and sulfuric acid --- makes regular trips between Japan and Chile.

Nippon Mining & Metals Co., Ltd and Nikko Logistics Partners Co., Ltd are shareholders. Operational details are found in the "Lines of Business" section; apart from Tokyo there are three further branches in Japan and one in China.

The house flag is simple, resembling the national one - white field - but having the red disk much larger. Moreover, a large white initial ‘N’ (no serifs) is placed in the disk.

The flag is white with two blue horizontal stripes, not touching the edges, a sort of blue curl placed in front of them and separated by thin white lines from those stripes. Of course the "curl" may represent some object used in towing. From the ship's page, and the following ones, we get to see various tugboats many of which fly above flag as a jack and moreover have it painted on the cabin in reversed colours.

Blue flag with a red stripe per bend, charged with the letters N S C in white.

Based in Tokyo, the company joined forces with other ISU members to respond to the pollution emergency when the Russian tanker 'Nakhodka' broke in two in the Sea of Japan, in January 1997.
