Daimon Station (Tokyo)
metro station in Minato, Tokyo, Japan
Daimon Station (大門駅, Daimon-eki) is a subway station in Minato, Tokyo, Japan, operated by the Tokyo subway operator Toei Subway. The station is named after the Shiba Daimon or Great Gate of Shiba, located just west of the station on the road leading to the temple of Zōjō-ji.
Daimon is adjacent to Hamamatsuchō Station, which is served by JR East and the Tokyo Monorail. On the Toei lines, Daimon is called "Daimon Hamamatsucho" in certain automated announcements. The Oedo Line station, which occupies most of the space between the Asakusa Line and the JR lines, was initially planned to be called "Hamamatsucho", but ultimately adopted the name of the existing Asakusa Line station.

Why this record matters
The phrase “metro station in Minato, Tokyo, Japan” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
Place names and jurisdictional language are key evidence: both can reveal earlier catalogue descriptions and overlooked record series. The source revision retrieved here is dated Aug 23, 2026. The linked authority identifier is Q247129. Authority coordinates are 35.657, 139.755. 2 of 3 selected statements include explicit references; 1 carry qualifiers and 0 use preferred rank. The first chronological checks are 1964 and 2000.
Architectural summaries often privilege surviving fabric and can understate demolished phases, contested use or displaced communities. 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.
