Shinchō Kōki

The book known today as Shinchō Kōki has many manuscripts and editions of the same original.^[1][8] There are more than 60 known manuscripts, with various titles given to them, including Shinchō Ki (信長記), Azuchi Ki (安土記), Ōta Izuminokami Nikki (太田和泉守日記).^[9] Some, such as the so-called Ikeda books handed down in the Ikeda clan, which was a family of daimyo, were commissioned by Ōta Gyūichi, who re-edited the contents to suit the client and transcribed it himself. Four sets of Shinchō Kōki in Gyūichi's own handwriting have now been identified, including the Ikeda book, and it is estimated that more than 70 sets existed in the past, including those written by people other than Gyūichi. However, as they are handwritten, their number is limited and only a few have survived. In particular, only two sets of Ōta Gyūichi's own handwritten books, complete with all volumes, have been found.^[8] This figure includes those that do not have all the books and those that once existed but are now missing.^[1][2]

It consists of 16 volumes, but the main volume is 15 volumes, and the first volume is thought to have been created later.^[10] There is no consensus among researchers as to the origin of the story; some say it was added later to a 15-volume book, while others say it was originally written as separate stories that were then combined into one by a copyist. There is also a theory that it was originally composed of 16 volumes.^[11] There are various versions of Shinchō Kōki, but the details of the order in which they were made, etc., are still under research and have not yet been clarified. However, the documents written by Gyūichi himself have one thing in common: they are all composed of 15 volumes.^[8]

When the chronicle, rewritten in modern Japanese, was published in 1992, nearly 10,000 copies were sold by 2008, including a newly revised edition published in 2006, reflecting Nobunaga's popularity.^[12]

An English translation was published in 2011 by Brill in cooperation with the Netherlands Association for Japanese Studies under the title The Chronicle of Lord Nobunaga. J.S.A. Elisonas and J.P. Lamers translated and edited the book.^[13]

  • A descendant of Ōta Gyūichi copied a book written by Ōta Gyūichi and gave it to the Maeda family in 1719. The original was later destroyed by fire.
  • Not open to the public, only available to researchers who have applied in advance.^[27][28] There are books published with permission, so you can find out what is written there.^[29]
  • This version contains many details not found in other versions, and is said to be either the oldest version that retains content omitted in the others, or a version in which content was altered and added by the scribe when it was written by hand.^[30]
  • This is the only version that states that a black man who came with missionaries from Africa was given the name Yasuke and was given a dagger, a house, and a stipend.^[31][32] This description does not exist in other manuscripts. In other versions, not only is there no mention of giving him a sword or other items, but the name Yasuke is not even mentioned.^{[33][32][34][35][36][37][38][39][40]}
    • Because the authenticity of the contents cannot be confirmed through document criticism, many Japanese researchers are cautious in their judgments and there is no unified view on the matter.^[41][34] On the other hand, many Western researchers credit this content.^[26]
      • In addition to the "Shinchō Kōki," a mention of his name and "a black man who was given a stipend" is confirmed in the "Ietada Nikki." Although there are many documents in Japan, no other historical documents have been found mentioning Yasuke.^[42][43] Declaration In the missionary's letters, several words "cafre"(but no names) and episodes have been found that refer to black slaves believed to be Yasuke. There is also a reference to a black man believed to be Yasuke in a letter by Luís Fróis, but there is no mention of Yasuke in Fróis's official document "Fróis's History of Japan" written by Fróis.^[42][43] The information that Yasuke was given a sword and a mansion is not mentioned anywhere other than in this Maeda edition of "Shinchō Kōki," so it is not possible to confirm this information in primary sources. Although Japanese researchers acknowledge that there was a man named Yasuke, biographies of the man have not been a major subject of study because they fall outside the scope of historiography and because of the lack of information available. ^[44]
      • Regarding the description of having Yasuke with certain tools and implements, there is a theory that the luggage Yasuke was made to carry was a sword. According to the record in "Buke Myōumokusyō(武家名目抄)," an encyclopedia of samurai compiled in the Edo period, the Oda clan often allowed commoner servants to carry swords.^[45] It is unclear whether this applies to Yasuke as well, since there is no description.
    • Hiraku Kaneko, a Japanese historian who published the book in Japan, stated that the part concerning Yasuke "has a certain degree of reliability, but we cannot deny the possibility that it was added with reference to other sources, such as the "Ietada nikki (家忠日記)," when the manuscript was made".^[46][34][47] On the other hand, because the copy was made using an early draft of "Shinchō Kōki" that had been passed down through the Kaga Ota clan, it is possible that it contains content that was omitted in the clean copy of the Ikeda version and other versions.^[48] In any case, he recommend that caution be exercised when dealing with the contents of this version.
    • A paper exists that states, "This document is reliable, but the description of Yasuke is likely to have been altered by later generations."^[49][26]

  • This is a less well-researched version, but there are areas where the description differs significantly from the others. In particular, the contents of the first volume have changed, and significant additions have been made. Some believe that the additions may have been made by someone who read "Hoan Shinchō Ki" while making the manuscript, but others believe that it is an early manuscript before various details were omitted, since it contains more detailed descriptions than "Hoan Shinchō Ki".^[50]

Oze Hoan read the Shincho-kōki and was dissatisfied that it was accurate but not interesting enough. Therefore, he created a book that incorporated Confucian values and incorporated many adaptations, and sold it widely as a woodblock print. This version was the first to be produced by letterpress printing. The exact date of writing is unknown (it is said to have been around 1611, but some say it was between 1604 and 1622). This is the "Hoan-Shinchō-Ki(甫庵信長記)." Although the content is based on Shincho-kōki, many adaptations have been added, making it less valuable as a material.^[17]

During the Edo period, Toyama Nobuharu(遠山信春) attempted to restore the Hoan-Shinchō-Ki to its correct content as much as possible, since it had been heavily embellished and was of very low quality. This resulted in the creation of the "Sōken Ki (総見記)". It is said that it was created around 1685.The source material, Hoan-Shinchō-Ki, itself has many errors, and as time has passed since the original source material, Shincho-kōki, was created, there are many contents that cannot be confirmed. Reliability further deteriorated. It has several other names, and is sometimes called "Oda Gunki(織田軍記)" or "Oda Chiseiki(織田治世記)."^[17]

As a young man, Ōta Gyūichi served the Oda clan for his skill with the bow and arrow, and served Nobunaga as a fighter, but in later years his work as a government official became his main responsibility, including serving as a magistrate for land inspection. Before the Honnō-ji Incident, he held the position of deputy of Namazumi in the Ōmi Province, and after Nobunaga's death he became secretary to Niwa Nagahide. He then served Toyotomi Hideyoshi and Hideyori. He continued to write during the reign of Tokugawa Ieyasu, and there is a memo written in 1610 when he was 84 years old.^[2][5]

Ōta Gyūichi was of a very penmanship nature and wrote down daily events in diaries and notes, which led to the compilation of the chronicle.^[1][5]

After the death of Gyūichi, his descendants were largely split into two groups. One was the Asada Domain (Settsu Ota Clan), and the other was the Kaga Domain (Kaga Ota Clan).^[51] The "Shinchō Kōki" and related documents were left in each family, and research is currently underway on them. Documents handed down in the Settsu Ota Clan state that Gyūichi began writing when he was in his 70s.^[52]

His lord, Nobunaga, is naturally written about favourably.^[1] One episode that illustrates Nobunaga's kind-hearted side is the Yamanaka no Saru (Japanese: 山中の猿; lit. ' Yamanaka's Ape') episode. In the village of Yamanaka, there was a disabled beggar called Yamanaka no Saru. Nobunaga gave the villagers 10 pieces of cotton and asked them to build him a hut. Nobunaga further told his neighbours that he would be happy if they would share with him a harvest each year that would not be a burden on them.^[5][53] However, he did not ignore what was inconvenient for Nobunaga, and on the other hand he also describes episodes that illustrate Nobunaga's misdeeds and brutality. As for the siege of Mount Hiei, the book describes the horrific scenes in a straightforward manner: Enryaku-jikonpon-chūdō and scriptures were burnt to the ground, and monks and non-monks, children, wise men and priests were decapitated. In another episode reads: The court ladies of the Azuchi Castle went on an excursion in Nobunaga's absence, but Nobunaga returned to the castle unexpectedly early. Knowing Nobunaga's character, these women were too frightened to return to the castle and asked the elder to apologise to him. This added fuel to the fire, and Nobunaga, furious as a flame, not only defeated them but also the elder.^[1][5]

In historiography, biographies and war chronicles are regarded as secondary sources based on primary sources such as letters. In fact, "Shinchō Kōki" is a secondary source. However, the "Shinchō Kōki" was written by a contemporary of Nobunaga, and the author did not like to adapt the content of the book and described it as accurately as possible. For this reason, although "Shinchō Kōki" is a secondary source, it is treated as a reliable source, just like a primary historical source. Gyūichi was not so senior among Oda's vassals and the information he had access to was not perfect. Also, in manuscripts, the transcribers sometimes made mistakes, intentionally rewritten or added things that were not written down. However, among researchers, its credibility stands out compared to other similar documents and is considered trustworthy.^{[1][2][15][16][54][55][56]}

Although this literature is considered reliable, it is not entirely free of errors. It remains a secondary source. Therefore, research should not rely entirely on this literature, but should compare it with other primary and secondary sources, as well as with other manuscripts of this book, to provide an appropriate source criticism.^{[57][15][58][16][59][54]} However, it is sometimes mistaken for a primary source for reasons such as "Ōta Gyūichi was a vassal of Oda Nobunaga" and "it is as reliable as a primary source".^[60] It has been pointed out that while Japanese researchers compare multiple versions of the "Shinchō Kōki" in their research, many Western researchers rely on a specific version of the "Shinchō Kōki" and do not properly criticize the historical record.^[26]

Most of the extant editions have the external title Shinchō Ki, but to avoid confusion with Oze Hoan's kanazōshi of the same title, which is described below, the chronicle is generally called Shinchō Kōki. In contrast, Hoan's version is called Hoan Shinchō Ki, or simply Shinchō Ki.^[2]

Shinchō Kōki is an indispensable historical book when talking about Oda Nobunaga. The life of Nobunaga, one of the most well-known figures in Japanese history, has been adapted into novels, manga, TV dramas, films, and video games many times in the past, and most of his life and episodes depicted in them are based on this book.^[1][2]

Oze Hoan, a Confucian scholar of the Edo period, wrote a war chronicle called Hoan Shinchō Ki (甫庵信長記) based on Shinchō Kōki (信長公記), adding other anecdotes passed down in the public. Hoan was also the best-selling author of those days, having published other works such as Hoan Taikōki, a biography of Toyotomi Hideyoshi. It was published in the early Edo period (1611 or 1622) under the title Shinchō Ki. It then became a huge hit as a commercial publication and was reprinted throughout the Edo period. It is not highly valued as a historical document, as it contains many fictional stories. However, it was accepted by the masses because it was novelistic, written in an amusing manner, with Hoan's subjectivity and Confucian philosophy. On the other hand, Gyūichi's Shinchō ki was rarely seen by the general public throughout the Edo period. For reasons unknown, its publication as a printed book was prohibited by the Edo Shogunate and it only spread in manuscript form. Therefore, it was not Shinchō Kōki but the Hoan Shinchō Ki that was widely read by the common people, and its contents spread as a common knowledge among the people of the time. And even after the Meiji era, many people, including historians, have talked about Nobunaga until recently based on the knowledge of Hoan Shinchō Ki, which is different from historical facts.^[1][2]
