两次量米，为什么数量不同？

Ōnga chōshi (遠賀町誌; Ōnga Town, 1986), part 5, chapter 4, 「年貢の収納」, section 2, prose discussing the Fukuoka bale of three tō and three shō, the additional shō, and further allowances for shipment to Osaka. This is a local historical synthesis drawing on domain records, not a national definition of the tax bale. The supplementary rice and credited quantity are kept distinct; the history's proposed modern weight equivalents are not used. https://www.town.onga.lg.jp/site/choshi/26906.html

Satō Yūka (佐藤祐花), 「古代の度量衡」, Fukuoka City Museum, exhibition no. 603, 12 September–5 November 2023, introductory discussion of the Shoku Nihongi entry for 702, the statutory inspection arrangements, and the decree of 798 in Ruijū Kokushi, vol. 80. The court's accusation is reported as an accusation. The discussion uses the museum's account of these texts rather than an independently collated edition of the ancient laws. https://museum.city.fukuoka.jp/sp/exhibition/603/

Midorikawa Kazuo (緑川和夫), “Measures of Volume and the Use of De Facto Standards in Eastern Japan during the Medieval Period,” Socio-Economic History 78, no. 1 (2012): 99–118, DOI 10.20624/sehs.78.1_99. The published English abstract supplies the regional groupings and the movement of a trading standard through Ōmi and Kyoto. Its account supports convergence and subsequent adoption, not a reconstruction of individual transactions or a claim that every medieval measure was already identical. The detailed article was not available for consultation. https://www.jstage.jst.go.jp/article/sehs/78/1/78_KJ00008128138/_article/-char/en

Agency for Cultural Affairs, Cultural Heritage Database, 「福井家京枡座関係資料」, record 213439, paragraphs on the Edo/Kyoto offices and the four categories of surviving material. Particularly relevant are the technical and inspection records and the master vessels supplied by Kyoto authorities. These collection descriptions establish the apparatus of production and checking; they are not a measurement of every surviving vessel or a record of compliance in all thirty-three provinces. https://online.bunka.go.jp/db/heritages/detail/213439

Ōnga chōshi, part 5, chapter 4, section 2, prose beginning with the measuring of rice in the presence of village officials, followed by the 1740 leveling provision and later district-specific supplementary containers. The numerical tables have not been used to reconstruct regional averages. The chapter also records uncertainty about the precise local introduction date of the later standard; no exact implementation date is asserted here. Same URL as note measure01.

National Metrology Institute of Japan, AIST, 「メートル条約締結と原器の来日」, sections 「メートル条約の締結と日本国の加入」 and 「度量衡法と尺貫法」. Used for accession in 1885, allocation in 1889, arrival in 1890, and the explanation of the Japanese metre prototype's temperature-dependent reference interval. The 0.15°C condition belongs to the historical statutory definition, not to a recommendation for ordinary measurement today. https://unit.aist.go.jp/nmij/library/nmij_icp/introduction.html

National Metrology Institute of Japan, AIST, 「日本国メートル原器」, descriptive sections on the 1,020 mm bar and the line-standard definition. The overall object length is distinguished from the interval representing the metre. The account is textual and does not claim an independent measurement of the prototype. https://unit.aist.go.jp/nmij/library/nmij_icp/metre.html

Doryōkōhō (度量衡法), Law no. 3 of 1891, articles 1–5 and 17, historical statutory text in Nagoya University's Japanese Historical Legislation database. These provisions establish the reference definitions, the special cloth measure, permitted metric units, and the 1 January 1893 commencement date. Only the transcribed statute is used, not the database's automatically generated explanatory material. https://jahis.law.nagoya-u.ac.jp/lawdb/l/124a0003

同法第6—12条：基准器的保管与复制、许可、检定、行政责任与检查。这些是规定的安排，未表明每件量器都按期受检。网址同注measure08。

Hokkaido Government, 「昔の計量器」, introduction dating the verification office to 1893 and the individual descriptions of historical length and capacity instruments. The displayed reference shaku is expressly identified as a replica; the collection is not treated as a set of objects all manufactured in 1893. https://www.pref.hokkaido.lg.jp/kz/krk/mukashi.html

Doryōkōhō (1891), articles 19–21, especially article 20's seven-year transition for verification of older instruments and the restriction on subsequent commercial use and sale without verification. The transition concerned instruments, not a seven-year deadline for abandoning every Japanese unit. Same URL as note measure08.
