Hanawa Hokiichi: Life and the Making of Gunsho Ruiju

Hanawa Hokiichi (塙保己一) was a blind scholar active during the Edo period. After losing his sight in childhood, he reduced barriers to reading through his teachers' instruction and his students' copying of texts. Gunsho Ruiju (群書類従), completed in 1819, remains an achievement in preserving historical texts.

This article follows records from Saitama Prefecture and Japan's Agency for Cultural Affairs, checked in October 2026.

Timeline of Hanawa Hokiichi's Life

Hanawa Hokiichi was born in 1746 and died in 1821. His birthplace is now part of Honjo City (本庄市), Saitama Prefecture (埼玉県). His entry into scholarship and the start of his publishing project were separate events.

Ages in the Saitama Prefecture timeline follow traditional Japanese age reckoning. Under this system, a person is counted as 1 in the year of birth. The stated age of 7 when he lost his sight must therefore not be treated as 7 completed years of age.

Why Studying Was Difficult After He Lost His Sight

Blindness prevented him from reading written characters by sight. Accessing the contents of books required other people to read aloud and explain them. To continue his studies, he also needed to build relationships through which he could receive that help.

In Edo, he joined the Todoza (当道座). The Todoza was an occupational organization for blind people. The Honjo City biographical profile also records his advancement within the organization.

At the time, new members were expected to train in occupations such as music or acupuncture. The reading and scholarship Hokiichi wanted to pursue required separate instruction. This background is documented in the biography included in Kokugakuin University's collection.

His difficulties therefore cannot be explained by the loss of sight alone. Finding people to read books to him and teachers to instruct him was another challenge. He also needed room to continue his studies alongside occupational training.

His Teacher's Permission and Scholarly Turning Points

His teacher's permission in 1761 gave him a foundation for continuing his studies. That teacher was Ametomi Kengyo (雨富検校). Hokiichi subsequently studied waka poetry, Shinto, and other subjects.

In 1769, he studied under Kamo no Mabuchi (賀茂真淵). Mabuchi was a kokugaku scholar who studied Japan's ancient texts. Kokugaku is the study of Japanese classics, ancient language, culture, and related subjects.

The Kamo no Mabuchi Memorial Museum's account shows the breadth of his learning relationships. Instruction from people around him also extended to history and ritsuryo law. Hokiichi's development was not the result of studying under just one teacher.

His turning points can be distinguished as follows.

What Kind of Book Is Gunsho Ruiju?

Gunsho Ruiju is a collection compiled from many historical texts. It is not a collection of works whose contents Hokiichi wrote entirely himself. Its purpose was to gather scattered records and pass them on.

The Saitama Prefecture explanation of Gunsho Ruiju describes its classification and the collaboration involved. The collected texts were divided into 25 categories. The main series, completed in 1819, comprises 666 volumes.

Collecting the texts required cooperation from people who held the source materials. Hokiichi sometimes traveled to distant places himself to obtain books. His students copied the books he borrowed.

The compilation can be understood through the following process. These tasks were carried out together over a long period. The sequence below is not a detailed work log for every text.

1. Locate and borrow texts scattered across different regions.
2. Have students transcribe the texts to create working copies.
3. Review the contents and correct errors in written characters and other details.
4. Classify and edit the texts by category.
5. Make woodblocks and print the texts as books.

His memory likely helped him use what he learned through readings aloud. But memory alone could not replace collecting and copying materials. The completed books contain the work of many people.

Wagaku Kodansho and the Foundation for Collaborative Research

Wagaku Kodansho (和学講談所) was a research and educational institution founded in 1793. Hokiichi sought to broaden the foundation for research into Japanese history and ritsuryo law. Ritsuryo was a legal system governing state administration, punishments, and other matters at the time.

The Saitama Prefecture account of the institution explains the background to its establishment. Ancient language and classical literature occupied a large place in kokugaku research at the time. A distinctive feature of the institution was that it provided a place to study history and ritsuryo together.

The rules included in Hanawa Kengyo Den (塙検校伝) show how collaborative learning worked. They required participants to read and correct designated texts together. During reading sessions, they were to focus on discussion and correction.

These rules distinguish Hokiichi's scholarship from individual memorization. Reading together was a way to share the contents of texts. Collaborative correction involved examining interpretations and written characters.

Materials from Wagaku Kodansho were passed down to later generations. Saitama Prefecture explains that they were inherited by the Historiographical Institute at the University of Tokyo. This is an example of an educational institution's materials remaining in use after its founder's death.

Completion in 1819 and the Project's Continuation After His Death

The completion in 1819 refers to the main series of Gunsho Ruiju. Zoku Gunsho Ruiju (続群書類従) was a separate follow-up project. This sequel was not completed during Hokiichi's lifetime.

Saitama Prefecture describes the compilation period as 41 years. This matches the count from 1779 through 1819 when both endpoint years are included. It should not be read as 41 full years measured from an exact starting date.

Accounts of 1779 and 1786 also differ in scope depending on the source. The prefectural timeline lists the decision and the implementation of the plan separately. The Agency for Cultural Affairs dates the start of woodblock carving and publication work to 1779.

Alongside his scholarly activities, he also took part in running the organization. Honjo City lists reform of the Todoza among his achievements. Saitama Prefecture describes his activities to improve the social standing of people with disabilities.

Why the Woodblocks Remain as Cultural Properties

The Gunsho Ruiju woodblocks are printing blocks that could be used to print the books repeatedly. Wooden boards carved with characters have survived as a means of reproducing the texts. They show how the books were published as well as what they contained.

The Japanese Agency for Cultural Affairs cultural property database lists 17,244 woodblocks. They were designated an Important Cultural Property on February 19, 1957. The storage facility is listed as Onko Gakkai (温故学会).

The Agency for Cultural Affairs explains that it is rare for the woodblocks of a large collected series to survive together. Their preservation value goes beyond their association with a historical figure. They are historical materials that document the publication of texts during the Edo period.

Records and Interpretation

Hokiichi's life needs to be studied with attention to the different types of sources. A timeline produced by a modern institution is not the same kind of record as an old biography. Conversations reported in biographies must also be distinguished from his own firsthand records.

What the Records Establish

Kokugakuin University (國學院大學) resource ID 40395 brings together several records. Among them, Onkodo Hanawa Sensei Den (温故堂塙先生伝) describes his learning process. Hanawa Kengyo Den includes the institution's rules.

The Kokugakuin University biographical resource is a starting point for checking each record. Statements included in a biography should be treated as that biography's account. They cannot be presented as entries in a diary or letters written by Hokiichi himself.

Assessments Shared by the Sources and This Article's Interpretation

The public institutional sources checked here regard the preservation of historical texts as a major achievement. Honjo City explains that Gunsho Ruiju is used in literary and historical research. There is no basis for going further and asserting that the entire scholarly community shares the same assessment.

The focus on access to education and collaboration is this article's interpretation. It rests on records of teachers' instruction, students' copying, and collaborative correction. It does not suggest that his blindness disappeared.

Points Requiring Further Verification

These records cannot measure the precise extent of his memory. The exact wording of particular remarks is also difficult to establish from biographical accounts alone. The sources checked here do not provide grounds for claiming that a separate scholarly debate exists.

• Treat anecdotes about his memory as accounts passed down in identifiable sources.
• Check the age-reckoning system used in the relevant timeline.
• Distinguish whether the start of publication means the decision, woodblock carving, or publication itself.
• Do not arbitrarily convert lunar-calendar dates in historical records to Gregorian dates.

The Difference Between Preserving Texts and Making Reading Accessible

The preservation of books and people's ability to read them are separate conditions. In Hokiichi's case, reading aloud and instruction supported his personal reading. Copying and publication created a way for texts to reach other people.

This distinction is useful when teaching about his life today. Explaining his achievements solely through personal determination leaves out the role of collaboration. Conversely, emphasizing only the support he received obscures his editorial and research work.

This table is an interpretation that distinguishes the roles found in the records. It does not mean that systems for educational accessibility today were the same then. Its value lies in asking who read, copied, and reviewed the texts.

Frequently Asked Questions

Was Hanawa Hokiichi a Kokugaku Scholar?

He was a kokugaku scholar who studied Japanese classics and history. He is known for organizing historical texts, including compiling Gunsho Ruiju. He also conducted research and taught at Wagaku Kodansho.

When Did He Lose His Sight?

The Saitama Prefecture timeline records that he lost his sight due to illness in 1752. He was 7 under traditional Japanese age reckoning. This must not be carried over directly into the modern system of counting completed years of age.

Did He Write All 666 Volumes of Gunsho Ruiju Himself?

Because it was compiled and edited from existing texts, it cannot be regarded as a book he wrote alone. His students copied the borrowed texts. Cooperation from the owners of source materials was also necessary to collect them.

Why Is the Compilation Said to Have Taken 41 Years?

Saitama Prefecture connects the decision in 1779 with completion in 1819. Counting both endpoint years gives 41 calendar years. This must be distinguished from elapsed time calculated using exact months and days.

Did He Also Complete Zoku Gunsho Ruiju During His Lifetime?

The sequel was not completed during Hokiichi's lifetime. Saitama Prefecture explains that the project continued after his death. It is inaccurate to combine the completion dates of the main series and the sequel.

Why Are the Woodblocks Preserved?

They are the original blocks used to print Gunsho Ruiju. The Agency for Cultural Affairs considers it rare for the woodblocks of a large collected series to be preserved together. They are materials that allow researchers to study both the contents of the texts and the publishing process.
