Overview
Blue Highway Line Co., Ltd. (株式会社ブルーハイウェイライン) was a Japanese shipping company headquartered in Minato, Tokyo, that operated long-distance ferry and freight routes. It originated in the late 1960s as Nihon Enkai Ferry (Japan Coastal Ferry), founded in 1969 with capital from Toshoku, Shokuhin Yusō, Mitsui Kinzai Kisen and Tokyo Kisen. After a capital increase in 1971, the Mitsui O.S.K. Lines group became the controlling shareholder, and the company launched its Tokyo–Tomakomai ferry route in 1972. It later added the Ōarai–Tomakomai route in 1985 and acquired routes from Nihon Kōsoku Ferry in 1990, adopting the Sunflower (さんふらわあ) brand and changing its name to Blue Highway Line in November 1990. The company's name and three-blue-line symbol expressed a vision of sea and land integrated transport: "Blue" for the sea, "Highway" for land, and "Line" for scheduled services. It unified its fleet under the Sunflower brand and expanded into freight ferry services, including a joint cargo ferry operation with Kawasaki Kinkai Kisen. However, economic recession, fare competition and rising fuel costs led to financial deterioration. Under Mitsui O.S.K.'s restructuring plan "MORE21," the company reorganized its freight routes in 1997–1998, spun off its Osaka–Shibushi route as Blue Highway Line West Japan in 2000, and in 2001 decided to liquidate. Its Ōarai–Tomakomai ferry and freight routes were transferred to the newly established Mitsui O.S.K. Ferry (now Mitsui O.S.K. Sunflower), while the Tokyo–Nachi-Katsuura–Kōchi route was discontinued on 1 October 2001. The company was dissolved in April 2002. Its legacy continues through successor companies and the Sunflower brand, which remains a major ferry operator in Japan.
History
The company was established on 18 August 1969 as Nihon Enkai Ferry Co., Ltd. (日本沿海フェリー株式会社) with capital of 100 million yen, jointly funded by Toshoku, Shokuhin Yusō, Mitsui Kinzai Kisen and Tokyo Kisen. The venture grew out of a late-1960s plan by Toshoku and Shokuhin Yusō to address truck driver shortages through long-distance ferry routes. In 1971, a second capital increase of 1.6 billion yen brought Osaka Shōsen Mitsui (later Mitsui O.S.K. Lines), Mitsui O.S.K. Passenger Ship and Mitsui O.S.K. Coastal Shipping in as 10% shareholders each, making the Mitsui O.S.K. group the controlling operator. The Tokyo–Tomakomai route began service on 27 April 1972 with two weekly sailings, becoming daily in April 1973. In 1975, the company obtained approval for a joint freight ferry service with Kawasaki Kinkai Kisen on the Tokyo–Tomakomai route, and the Cargo Ferry Center (CFC) was established on 1 July 1975, with freight ferry service starting on 1 October 1975. The Ōarai–Tomakomai route was licensed in June 1984 and launched on 16 March 1985, initially three times weekly. In 1987, a new livery was introduced with the new vessel Ōarai Maru. In 1989, the company agreed to take over Nihon Kōsoku Ferry's Tokyo–Nachi-Katsuura–Kōchi route, and in 1990 it acquired the Osaka–Shibushi–Kagoshima route as well. On 1 November 1990, it introduced a corporate identity and changed its name to Blue Highway Line Co., Ltd. In January 1991, it unified the livery and names of its six ferries under the Sunflower brand. The company continued to expand and reorganize: in 1991 it took over the coastal shipping division of M.O.C. Ways; in 1993 it made the Ōarai–Tomakomai route daily; in 1994 it acquired coastal routes and a car carrier division from Daizan Kaiun; and in 1996 it launched the Sunflower Club Gyro credit card service. However, financial difficulties mounted. In 1997 it rerouted the Tokyo–Tomakomai service via Ōarai as the "New Tokyo Route" and withdrew from the Tokyo–Chūgoku/Shikoku RORO business; in 1998 it withdrew from the Osaka–Naha container route. In 1999, passenger service on the Tokyo–Ōarai segment was suspended, and a high-speed RORO vessel was introduced on the Tokyo–Tomakomai freight route. In 2000, the Osaka–Shibushi route was spun off to Blue Highway Line West Japan. In 2001, facing accumulated losses of 4.7 billion yen and expected debt exceeding assets by 3 billion yen, the company decided to liquidate. The Ōarai–Tomakomai ferry and freight routes were transferred to the newly established Mitsui O.S.K. Ferry on 1 July 2001, and the Tokyo–Nachi-Katsuura–Kōchi route was discontinued on 1 October 2001. The company was dissolved in April 2002. Its three-line symbol continued to be used by land transport subsidiaries Blue Highway Express Hokkaido and Blue Highway Express Kyushu (now Sunflower Express), and the Sunflower brand was inherited by successor ferry operators.
