Some highlights from the ‘Company History’ section: founded in 1921 as ‘Tsurumaru Shoten’ becoming Co., Ltd in 1935 and renamed ‘Tsurumaru Kisen’ in 1938. Concentrating on port transportation and cargo handling from 1950 on. Warehousing starting in the ‘sixties e.g. for Nippon Steel. 1976, “a steelyard was built at Kokura-Nishiminato for the purpose of rationalizing steel handling”. 1981, start of industrial waste transport. 1989, ferry Kyushu-Tokyo. International expansion.

Tsurumaru owns two vessels and charters nineteen more; sixteen are consigned.

"Tsuru" means "crane", and the logo looks like it might consist of the stylized characters for "crane": ツル.
Eugene Ipavec, 25 July 2007


Yes, while "maru" means "disc" and in the flag the stylized characters above are enclosed in a disc: "ツル⃝"; it is a canting flag.

Tsurumi Sunmarine Co., Ltd is a Tokyo based shipping company, founded in 1947, flying a simple house flag shown on the homepage. English version located at http://www.trsm.co.jp/.

A large red initial ‘T’, serifed, is placed on a white field. Again, the national colours.

The company states that it carries “mainly Petroleum Products, LPG, Chemicals and Asphalt in Japan and South East Asian countries” representing for instance “about 25 percents of transported petroleum products (about 50 millions K/L per year) in Japan” which is considerable.

From the ‘History’ section: the company’s first name was ‘Tsurumi Yuso Co., Ltd. Thanks to early contact with local oil firms, business expanded quickly – later chemicals, asphalt, etc. were added to the trade. Also, various local and overseas subsidiary firms were established. The present company name was adopted in 2000 when the merger with Sunmarine, Ltd took place.

TThe ‘Vessels’ section indicates Tsurumi-Sunmarine’s strong position in the coastal trade (most ships are chartered).
