Shintei Bujutsu Ryuha Daijiten: Hoteiko (新訂 武芸流派大事典 補訂稿) stands as an extremely rare, privately distributed supplemental master-manuscript explicitly created to update, correct, and expand the definitive 1969 First Edition of the Bujutsu Ryūha Daijiten (武芸流派大事典). Rather than a standalone commercial book, this dense archival volume functions as a specialized primary source text that was strictly not for sale (非売品 – Hibaihin) to the general public. It was produced in a highly limited run and distributed exclusively to a select network of private subscribers, martial arts historians, and classical school heads (sōke). Today, it preserves hundreds of irreplaceable handwritten corrections, newly surfaced school lineages, master death dates, and precise typographical updates meant to modify the legendary 1969 master encyclopedia.

The Author & Editor: Kiyoshi Watatani (“The Master Registrar”)

• Lifelong Obsession: Kiyoshi Watatani (綿谷雪, 1903–1983) was a fanatical registrar of historical combat systems. He spent decades corresponding directly with living lineage heads (sōke), collecting hidden scroll reproductions (densho), and cross-referencing regional temple death registries to eliminate centuries of fabricated martial folklore.
• The Secretive Publisher: This volume was meticulously produced by Bugeicho-sha (武芸帖社), an elusive, highly specialized private press dedicated strictly to printing limited-run martial documents and historical errata for serious researchers and master practitioners.

Key Content & Page References

• Lineage Revisions (pp. 1–20): Contains precise adjustments to the core lineages of foundational schools. It includes critical biographical data fixes, such as updating the exact age of death to 76 for specific classical masters.
• Temple Location Mapping (p. 18): Logs critical geographic corrections for researchers tracking historical transmission paths. For example, it tracks the relocation of the Keiin-ji Temple to the Jōraku-ji Temple within Tokyo’s historic Ushigome Haramachi district.
• Complete System Overhauls (p. 24): Commands entire content replacements for specific lineages. It completely replaces older notes for schools like the Araki-ryu, directing researchers to insert comprehensive lineages drawn from the Zōho Bugei Shōden (Expanded Short Histories of Martial Arts).
• Chronological Corrections (p. 100): Fixes significant historical timeline errors in the main encyclopedia. Notably, it updates recorded event timelines from the Showa 17 era to the post-war Showa 47 (1972) era.

The Book’s Modern Legacy & Bibliographic Layout

This supplement represents the absolute peak of pre-digital martial arts historiography in Japan. It was physically constructed as a horizontal landscape manuscript (Yokohon / 横本) and was natively included as a key text within the rare, multi-volume library set titled Zoku Kobudō Bunkenshū (続 古武道文献集 / Continued Collection of Classical Martial Arts Literature) issued inside traditional protective library casings (Chitsu). Because it bypassed commercial distribution entirely, it is recognized today by elite international academics and classical martial arts (koryū) practitioners as an essential companion key. Without this supplement, reading the standard 1969 master dictionary leaves researchers open to relying on uncorrected errors and incomplete lineage records.
