Sakaisuji Line
metro line in Osaka, Osaka prefecture, Japan
The Sakaisuji Line (堺筋線, Sakaisuji-sen) is an underground rapid transit line in Osaka, Japan, operated by Osaka Metro. Its official name is Rapid Electric Tramway Line No. 6 (高速電気軌道第6号線), and in MLIT publications, it is written as Line No. 6 (Sakaisuji Line) (6号線（堺筋線）).
The Sakaisuji Line is unique in the Osaka Metro system in that despite being regulated as a tramway under the Railway Business Act like the other lines, the line was constructed as an extension of a line governed as a railway, specifically the Hankyu Senri Line, to which the Sakaisuji Line connects to at its northern end at Tenjimbashisuji Rokuchōme Station. Through services using both Osaka Municipal Subway and Hankyu rolling stock operates to and from the Senri Line and Arashiyama Line via the Kyoto Main Line.
History
The Sakaisuji Line was first envisioned in the Urban Transportation Council Report No. 3 (1958) as an underground line running from Tenjimbashisuji Rokuchōme to Tenma via Sakaisuji and Dobutsuen-mae, and it was to be operated by Hankyu Railway instead of the Osaka prefectural government. In 1963, the Urban Transportation Council Report No. 7 (1963) recommended that the southern terminus of the Sakaisuji Line be at Tengachaya instead of Tenma.

Why this record matters
The subject matters to the general reference register because the source frames it as metro line in Osaka, Osaka prefecture, Japan. Its deeper value depends on whether names, dates, institutions and citations support that framing.
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 Feb 17, 2026. The linked authority identifier is Q1143250. 1 of 1 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1958 and 1963.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
