武士为何向地位低于自己的商人借钱？

Mitsui Bunko, The Journey of Mitsui, chapter 18, “Money Exchange Stores (3): Feudal Lords,” especially “Lords and Benefactors” and the explanation of the Kii Tokugawa records. The 1784 request for 13,000 ryō, reduction to 9,500, and the exception made for important benefactors. The archive associates the movement of funds with the princess's marriage and residence; the essay does not treat that association as a complete itemization of the loan's expenditure or invent a face-to-face meeting. https://mitsui-bunko.or.jp/archives/eng_story18/

National Archives of Japan, Hatamoto and Gokenin, item 44, Kanpu gosata ryakki, call number 165-0044, twenty-eight volumes. The catalogue describes Ono Naokata's record, his son's 1757 promotion, the two-hundred-bale stipend and ten-ryō office allowance, seasonal payments, and the functions of the fudasashi. It also notes officially posted rates for converting the stipends. The essay does not claim that Naoyasu borrowed, equate bales with koku, or convert his pay into a misleading modern-money equivalent. https://www.archives.go.jp/exhibition/digital/hatamotogokenin/contents/44.html

Bank of Japan Currency Museum, “What Were the Currency Units Used during the Edo Period?” Gold denominations, silver valued by weight, copper cash, and the distinction between official and actual exchange rates. The essay describes historical payment forms, not present financial practice. https://www.imes.boj.or.jp/cm/english/

National Archives of Japan, Hatamoto and Gokenin, item 45, Gyōyōshū, also called Fudasashi gyōyōshū, call number 183-0585. The 1818 compilation by Ōgiya Sadatsugu, recognition of the brokers' association in 1724, and cases of kurayadoshi using violence to seek advances for rice-stipend retainers. The evidence documents cases, not the frequency of such behavior across all borrowers. https://www.archives.go.jp/exhibition/digital/hatamotogokenin/contents/45.html

Yasuo Takatsuki, “The Financial Dealings of the Lord Class,” Japanese Research in Business History 41 (2024), pp. 3–15, DOI 10.5029/jrbh.41.3. Sections II and III.2 distinguish domain and shogunal revenues and describe the Kamei–Kajimaya arrangement involving paper, candles, financial plans, and repayment from sales. The relevant full-text HTML sections were consulted. The essay does not adopt a single trajectory of impoverishment for all domains or treat every loan as rice-backed. https://www.jstage.jst.go.jp/article/jrbh/41/0/41_3/_html/-char/en

Osaka Exchange / Japan Exchange Group, “Dōjima Rice Exchange.” Domain warehouse-residences, auctions, redeemable rice bills, the authorized spot and futures markets of 1730, and the circulation of prices. The essay keeps rice bills and futures transactions distinct and does not infer that all domain revenues passed through Dōjima. https://www.jpx.co.jp/dojima/en/

Mitsui Public Relations Committee, historical series, “Edo Period,” chapter 3; and Mitsui Bunko, The Journey of Mitsui, chapter 16, “Money Exchange Stores (1): Chartered Purveyor of Exchange Services to the Shogunate.” The complementary directions of government remittances and commercial purchasing payments. The explanatory account describes offsetting payments, not an assertion that coin transport ceased. https://www.mitsuipr.com/history/edo/03/ ; https://mitsui-bunko.or.jp/archives/eng_story16/

Mitsui Bunko, The Journey of Mitsui, chapter 16, figure 16a, Okawasedome (exchange-transaction ledger), 1792. The catalogue explains silver obtained from rice taxes and the recording of receipt and payment dates. The essay uses the archive's explanation rather than claiming a fresh transcription of every entry. https://mitsui-bunko.or.jp/archives/eng_story16/

Hideshi Itoh, Takashi Shimizu, and Yasuo Takatsuki, “Complementarities between Long-Term Relationships and Short-Term Contracts: Case of Early Modern Japan,” Kobe University, Research Institute for Economics and Business Administration, Discussion Paper 2025-33, public abstract. Used for the distinction between the enforceability of loans to daimyō and contracts among merchants, and the proposed role of continuing relationships. The full paper and its formal model were not consulted; the separate Kamei example is documented in note sc05. https://www.rieb.kobe-u.ac.jp/academic/ra/dp/English/dp2025-33.html

Mitsui Bunko, The Journey of Mitsui, chapter 21, “A Changing Society, Mitsui's Agony,” especially “Financial Extortion” and figure 21a, internal correspondence concerning the 1762 demand. The essay uses the documented 50,000-ryō demand and the archive's description of pressured advances, not its sweeping generalization about all merchant profits being untaxed or all lords' finances following the same course. https://mitsui-bunko.or.jp/archives/eng_story21/

Noburu Kobayashi, “Merchant Family Management and an Analysis of Ledgers from the Late 19th Century,” Japanese Research in Business History 41 (2024), pp. 37–52, DOI 10.5029/jrbh.41.37, section IV.1. The relevant full-text HTML discussion supports the two Kajimaya houses, Osada's failure around 1874, and the uneven survival of merchant archives. No new balance-sheet reconstruction is claimed. https://www.jstage.jst.go.jp/article/jrbh/41/0/41_37/_html/-char/en
