Bibliography / 出典一覧¶

The master source list for the Sagishima wiki. Pages cite by key (the bold short name); add the key to a page's sources: frontmatter and reference it inline.

Standing rule: cite PRIMARY sources only. A primary source is the original record: a note.com post, a thered.school page, a primary RDS document, the film, the journal article. Do not cite Claude-generated syntheses (the Sagishima Compendium, audit-folder READMEs, the audit .md mirrors of website content). Those may be linked as "related / see also," but never appear in a ## Sources block. If a fact's origin is unknown, say so and flag it for verification rather than citing a synthesis. See /memory/feedback_cite_primary_not_secondary.md.

Local history books (Sagishima)¶

Note on these two (decision, 2026-06-04). Both books are themselves compilations that quote deeper primaries (三原市史, 芸藩通志, 豊田郡誌, 藤井家文書, 国郡志 survey documents, school anniversary volumes, prefectural shrine registers). Per Xavaar's instruction, because the deeper originals are not practically obtainable, these books are cited as primary for this wiki; where the book names the deeper source, that source is noted in the citation (e.g. "双鷺洲 p.80 → 三原市史"). This is a scoped exception to the standing cite-primary-not-secondary rule. See /memory/feedback_cite_primary_not_secondary.md.

さぎしま讃歌 (Sagishima Sanka, "Hymn to Sagishima"): a photo-history of Sagishima and Kosagishima by Yamashita Hiromi (山下博巳), subtitle 今は見られないさぎしまの風景; ~323 photographs (Nishihara Michio 西原通夫 and many contributors); colophon 1985, corrected 2012-01-27 (Heisei 24, the 1985-vs-2012 relationship unconfirmed); printed by Kure Seihan Printing Co.

Tertiary (figures corroborated, not a primary)¶

Japanese Wikipedia, 佐木島: https://ja.wikipedia.org/wiki/佐木島. Drawing on official data: 面積 8.72 km², 周囲 18.2 km, high point Taiheizan 267.5 m; population 596 / 380 households / aging 71.08% (2023-03-31); 1956-09-30 merger into Mihara as 鷺浦町; agriculture-dominated (citrus, melons, watermelons, Chinese chives), no established fishing tradition; Triathlon since 1990, 33rd edition 2024 final; neighboring 小佐木島. A tertiary source: it confirms the official figures (resolving the area question) but trace to the underlying census/municipal data where it matters.

These are first-person, regularly-updated island accounts. They cannot be fetched or mirrored into this wiki (Instagram requires login), but they are pointers worth following for current island life.

@isso_okranch: https://www.instagram.com/isso_okranch/. Isso (Kawamoto Yoshishige)'s own Instagram ("OK Ranch"); he posts regularly. A primary living record of his farming and island knowledge; central to the Isso-San Anthropology initiative. (Identified by Xavaar.)
@sagigram.2021: https://www.instagram.com/sagigram.2021/. An account documenting Sagishima daily life, scenery, and events. (Identified by Xavaar.)
@thered.school: https://www.instagram.com/thered.school/. The Red Dot School's own Instagram; the institution's most current public channel alongside its note.com journal. (Identified by Xavaar.)
@sagishimablue (さぎしま碧 / Sagishima Blue): https://www.instagram.com/sagishimablue/. A share-kitchen and rental-cycle at the Sagi Port entrance, opened June 2025 (address 鷺浦町須波3323, Mihara 723-0021; TEL 080-2648-8412). See Community and Migration. (Identified by Xavaar.)

SECONDARY syntheses (DO NOT CITE)¶

These are useful navigational documents but are downstream syntheses (several Claude-generated). Link them as "related," never as a source.

Sagishima Compendium: ../Sagishima_Compendium.md (+ .docx). The long-form companion; itself sourced to the items above. Trace to its primaries instead.
Audit .md mirrors and READMEs: e.g. ../../Audit_RDS/05_Output_and_Impact/Sagishima_Data_Project.md, ../../Audit_RDS/01_People_and_Personnel/RDS_People_Research_Findings.md, audit-folder README.md files. Cite the thered.school page or note.com post they summarize.

How to add a source¶

Confirm it is primary. If it is a synthesis, find what it drew from and cite that instead.
Give it a short bold key and a stable locator (post ID, URL, file path, archive ID).
Reference the key from page sources: frontmatter and inline at the claim.
If you cannot find the primary, write "not yet traced to a primary; flagged for verification" rather than citing a synthesis.
