The Hokusō Line (北総線 Hokusō-sen?) is a commuter rail line operated by the Hokusō Railway in Japan. It runs between Keisei-Takasago Station in Katsushika, Tokyo and Inba-Nihon-Idai Station in Inzai, Chiba.

In July 2010, an extension of the Hokusō Line, called the Narita Sky Access Line, opened to Narita Airport Station, making the line a new link between Tokyo and Narita Airport.

The rail line had been opened in March 1979 on a temporary basis. As other tracks were connected, it changed name to "Hokusō Kōdan Line" in April 1987. Over 17 years later, the railway properties of the HDC corporation transferred to Chiba New Town Railway (千葉ニュータウン鉄道 Chiba Nyūtaun Tetsudō?), on July 1, 2004, and the whole line was renamed as the Hokusō Line.

History [edit]

Western section [edit]

The line was planned as a railway access to Chiba New Town. Initially planned by a committee of the then Ministry of Transport, the route was numbered "Line 1", as the northern extension of Tokyo Metropolitan Bureau of Transportation (Toei) Line 1 (present Asakusa Line) to Komuro area of Chiba New Town. In 1979 the first phase section between Kita-Hatsutomi and Komuro opened. The through-operation via Shin-Keisei Line to Matsudo began, on a temporary basis until the second phase section could connect the town directly to the Keisei and Asakusa Line network.

The second phase line to Keisei-Takasago on Keisei Main Line opened in 1991, and through-operation began. In the following year, Shin-Keisei included Shin-Kamagaya Station as a transfer station, and abandoned the temporary route.

Eastern section [edit]

The section east of Komuro was initially the eastern end of a once-planned Chiba Prefectural Railway (千葉県営鉄道 Chiba Ken'ei Tetsudō?) (II, apart from the first which opened the Tōbu Noda Line and the Kururi Line) as an extension of Line 10 (Shinjuku Line). The line was to be built from Motoyawata via Komuro to parallel to the line above, then to terminate at present Inba-Nihon-Idai. The first section between Komuro and Chiba New Town Chūō was opened in 1984, and the operations were commissioned to the present Hokusō Railway.

Extension to Narita Airport [edit]

After the abandonment of the planned Narita Shinkansen, routes of rapid transit to Narita Airport had long been discussed. For a utilization of partially completed tracks of the Shinkansen, JR East and Keisei lines to Narita Airport were realized. A much faster line had long been needed, and for that purpose the first priority was the Keisei – Hokusō route. In 2001, a new Cat-3 entity, Narita Rapid Rail Access (成田高速鉄道アクセス Narita Kōsoku Tetsudō Access?) commenced building of a new line connecting Inba-Nihon-Idai to the junction to Narita Airport Rapid Railway (成田空港高速鉄道 Narita Kūkō Kōsoku Tetsudō?) which is a Cat-3 company of existing access railways, the tracks of the formerly planned Narita Shinkansen. The express trains are operated by Keisei as a Cat-2 operator with maximum speed at 160 kilometres per hour (99 mph), the fastest in Japanese private railway together with Hokuetsu Express, which enables a 34-minute journey from Nippori to Narita Airport. The line opened in July 2010.
