Source-derived summary

The Keihin–Tōhoku Line (Japanese: 京浜東北線, Hepburn: Keihin-tōhoku-sen) is a railway line in Japan which connects the cities of Saitama, Kawaguchi, Tokyo, Kawasaki, and Yokohama. It is part of the East Japan Railway Company (JR East) network. The line's name is derived from the characters for Tokyo (東京), Yokohama (横浜) and the Tōhoku Main Line (東北本線). The line runs parallel with the Tōkaidō Main Line between Yokohama and Tokyo and the Utsunomiya Line (part of the Tōhoku Main Line) except between Ueno and Akabane stations where the two lines are physically separate and thus alternate routes.

Most Keihin–Tōhoku Line trains run through onto the Negishi Line between Yokohama and Ōfuna stations. As a result, the entire service between Ōmiya and Ōfuna is typically referred to as the Keihin–Tōhoku–Negishi Line (京浜東北・根岸線) on system maps and in-train station guides. Keihin–Tōhoku–Negishi Line trains are recognizable by their light blue stripe (the line's color on maps is also light blue).

Service outline

Trains run every 2–3 minutes at peak hours, every 5–6 minutes during the daytime, and less frequently the rest of the time. In general, these trains are classified as "Local" (各駅停車, Kakueki-Teisha), stopping at all stations en route. However, all trains in the daytime (10:30–15:30) are classified as "Rapid" (快速, kaisoku).

Editorial summary

This brief starts where responsible research should: with the source description of “Keihin–Tōhoku Line” as railway line in Japan. Everything that follows is an evidence route, not borrowed authority.

Editorial reviewA concise reference frame for defining the subject, testing terminology and identifying the institution closest to the evidence. The current 208-word lead offers orientation but no explicit four-digit date, so chronology should not be assumed. The selected authority fields contribute no independent date. The account is most persuasive where Keihin, Tōhoku and Line can be independently traced.
Editorial analysis

Why this record matters

The subject matters to the general reference register because the source frames it as railway line in Japan. Its deeper value depends on whether names, dates, institutions and citations support that framing.

Evidence profile

The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Sep 16, 2026. The linked authority identifier is Q1197028. None of the 0 selected statements returned an explicit reference.

Critical limits

The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.

How to read it

Use the entry as an orientation point, then follow its citations and revision history. Names, dates and institutional relationships should be checked against the original record.
