It was the first chronography compiled by the royal government and was presented to King Shō Kei in 1713.

Key takeaways

  • Ryūkyū-koku yurai-ki belongs to science; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Ryūkyū-koku yurai-ki to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Ryūkyū-koku yurai-ki from memory before moving on to harder problems.

Reference excerpt

Ryūkyū-koku yurai-ki (琉球国由来記; Records of the Origin of the Ryūkyū Kingdom) is a chorography compiled by the government of the Ryukyu Kingdom. It was the first chronography compiled by the royal government and was presented to King Shō Kei in 1713. It is an essential resource for Okinawan studies. This book was largely written in Japanese. Later Tei Heitetsu (鄭秉哲) wrote its Kanbun translated version and titled it Ryūkyū-koku kyū-ki (琉球国旧記).

Outline The preface of the book, titled “Preface to the Records of the Origin of Various Matters” (諸事由来記序), states that it was presented to the king on the 11th lunar month of 1713 (Kangxi 52), which is a clear indication of the date of its establishment. In addition, the “Preface to the Records of the Origin of Various Matters” describes the purpose of the book. It states that because the government did not have official chronicles, the origins of the various official formalities in the Forbidden Castle (Shuri) and of the ceremonies held each month and each year were not clear. This matter could not be considered lightly according to the Virtuous Government Principles, so that “our King” had his subject investigate the matter. According to the “Commentary on the Ryūkyū-koku yurai-ki” written by Fuyū Iha, the ‘Our King’ mentioned in the “Preface to the Records of the Origin of Various Matters” is King Shō Kei, the 13th king of the Ryūkyū Kingdom. The same commentary also states that ‘this book should also be called the Engishiki (延喜式, "Procedures of the Engi Era") of the Ryukyu Islands.’ At the end of the “Preface to the Records of the Origin of Various Matters”, the following persons are listed as having been involved in the compilation of the book. Sessei (Prime Minister) Shō Yū Prince Tomigusuku Chōkyō 向祐(豊見城王子朝匡) Sanshikan (Council of Three) Shō Genryō Tashima Uēkata Chōyū 向元良(田嶋親方朝由) Ō Shidō Ishadō Uēkata Seifu 翁自道(伊舎堂親方盛富) Ma Kento Urasoe Uēkata Ryōi 馬献図(浦添親方良意) Origins of the Old Rules Magistrates Shō Ihei Nakazato Aji Chōei 向維屏(仲里按司朝英) Ei Tokuan Itokazu Uēkata Chōchū 頴徳安(糸数親雲上朝忠) Origins of the Old Rules Secretaries Shō Iban Genga Uēkata Chōchū 向維藩(源河親雲上朝忠) Shō Kōgyō Ukuda Uēkata Chōgū (宇久田親雲上朝遇) In “Ancient Literature Lectures vol. 11: Record of Miraculous Events (霊異記 Reiiki), Clans Origins (氏文 Ujibumi) and Dependent arising (縁起 Engi)”, it is considered that the prime minister and the council of three, as the persons taking responsibility for the royal government, were only supervisors mentioned for administrative purposes, and that the actual research had been carried out by the Origins of the Old Rules Magistrates. In the same book, it is said that the period of creation of the post of “Origins of the Old Rules Magistrate” is made quite clear by the mention in the genealogic records of the Sanshikan Tashima Chōyū of the creation of the “Old Records Office” on the 2nd day of the 3rd month of the lunar calendar of 1703 (Kangxi 42). Since we know the date of creation of the post of Origins of the Old Rules Magistrate, it can be deduced that the compilation of the Ryūkyū-koku yurai-ki lasted from the 2nd day of the 3rd lunar month of 1703 (Kangxi 42) to the 11th lunar month of 1713 (Kangxi 52). The “Commentary on the Ryūkyū-koku yurai-ki” speculates that the Old Records Office was a temporary department, which was abolished with the completion of the book, as there is no mention of the position in the book's second volume, ‘Lists of the Official Posts’. The same book also speculates that the Old Records Office became independent from the Genealogical Records Office (that had been established in 1689 (Kangxi 28)) shortly after the completion of the Genealogy Book of Chūzan (Chūzan Seifu, 中山世譜). With the completion of the Ryūkyū-koku yurai-ki the Old Records Office was abolished, with its affairs being taken over again by the Genealogical Records Office. The same book (“Commentary on the Ryūkyū-koku yurai-ki”) states that for the various rituals of each place mentioned in the Ryūkyū-koku yurai-ki, instructions were sent to each Magiri Banjo (Guard House) [1] for the local magistrates to research and document the origins of the old rituals in their jurisdiction. It seems that information from those reports were then skimmed and rearranged to compile the book. The submitted reports were gradually destroyed after the compilation was completed, so that only a few remain today [2], but a comparison of these reports and the book permits to see the general policy behind the compilation of the book. In addition, there are mentions of the “Visible Ways of the Gods Account” (見神道記) in the chapters “Ameku Temple’s Great Gongen’s Origin” (天久山大権現縁起) and “Futenma Temple’s Three Location Great Gongen’s Origin” (普天満山三所大権現縁起) of the 11th volume of the Ryūkyū-koku yurai-ki (titled “Secret Origins of Various Temples”密門諸寺縁起 ), implying that several paragraphs of this volume referred to the Ryūkyū Shintō-ki (琉球神道記 “An account of the ways of the gods in Ryūkyū”), suggesting that the Ryūkyū Shintō-ki was used as a reference work when this volume was compiled.

Worked examples

Example 1 — a first encounter with Ryūkyū-koku yurai-ki

Start with the simplest possible case. Write down what Ryūkyū-koku yurai-ki claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Ryūkyū-koku yurai-ki before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Ryūkyū-koku yurai-ki ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Ryūkyū-koku yurai-ki

In research
Ryūkyū-koku yurai-ki appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Ryūkyū-koku yurai-ki in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Ryūkyū-koku yurai-ki is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1713 non-fiction books, Books of the Ryūkyū Kingdom, Geography books, so understanding it makes those chapters shorter.
In everyday life
Look for Ryūkyū-koku yurai-ki outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
