Tier justification
Tier 3: Wikipedia is pointer-only per CREDIBILITY.md. Used here strictly to record the day-month tokens (6 August 1917 / 18 April 1966), the Singapore birthplace, and the Tokyo death-place. The biographical narrative on Yamahata’s August 10, 1945 Nagasaki photography is independently anchored in this repo at Tier 2 via src-obrian-2008-nuclear-family-of-man (which references Atomized Nagasaki) and via primary-press citations in src-takenaka-2020-popular-inquiry-japan (Asahi Graph, April 29, 1956).

Notes
- Per
CREDIBILITY.md, Wikipedia is treated as a pointer source. The 6 August 1917 / 18 April 1966 day-month tokens are corroborated by the structured-data record at Wikidata Q8062693 (+1917-08-06/+1966-04-18, fetched 2026-05-10 to.scratch/wikidata-yamahata.json); same Wikipedia community pool, not strictly independent. - The 1917 / 1966 year-only resolution is independently anchored at Tier 1 by the ICP constituent page (
src-icp-yosuke-yamahata), which displays “1917 - 1966” verbatim in the date-registry element. - The Singapore birthplace is notable: Yamahata was born in Singapore (under British Straits Settlements administration) on 6 August 1917 — exactly 28 years to the day before the Hiroshima atomic bombing (August 6, 1945). Wikipedia’s note that he was “Hibakusha” (atomic-bomb survivor / witness) is contextual: he photographed Nagasaki on August 10, 1945, as part of a Japanese army film unit, the day after the bomb fell.
- The page does mention Family of Man in the broader Yamahata Wikipedia narrative; this round’s fetch did not extract a verbatim FoM-attribution string from the body text (only from the infobox / categories), but the connection is independently anchored in this repo at Tier 2 via
src-takenaka-2020-popular-inquiry-japanp. 47 (“Steichen and the committee decided to add 60 works by Japanese photographers, among which five of Yosuke Yamahata’s aftermath photographs from atomic bombing on Nagasaki were included”) and via the Tokyo-tour Emperor-curtain controversy attested insrc-obrian-2008-nuclear-family-of-manand the Asahi Graph April 29, 1956 primary-press citation. - The MoMA Master Checklist (
src-moma-exh-0569-master-checklist) records Yamahata’s plate at #450, Section 39 Faces, credited to “G. T. Sun Company” (his agency) — not any of the well-known Nagasaki post-bombing photographs Takenaka 2020 describes as added in Tokyo. The five Yamahata Nagasaki photographs added in the Tokyo tour were not part of the original New York 1955 exhibition (Takenaka 2020 p. 47 explicit: “specially added to the installation”), so the MoMA checklist plate (#450) and the five Tokyo-added Nagasaki plates are distinct objects. - Verified against fetched source on 2026-05-10 via
