The 1978 edition of the Bujutsu Ryūha Daijiten stands as the ultimate expanded milestone in Japanese martial arts historiography. Re-released nearly a decade after the original out-of-print 1969 census, this massive 974-page masterwork was completely rebuilt by the authors to integrate newly discovered rural lineage documents, critical headmaster death dates, and corrected cross-references. It serves as the absolute definitive edition of the premier historical martial arts encyclopedia ever compiled, offering deep encyclopedic verification for classical samurai and ninja combat systems.

Rare and Unusual Facts About the Volume

• The Decade of Reconstruction: Following the rapid sell-out of the original template, the authors spent nearly ten years tracking down missing rural family documents to add hundreds of newly discovered combat schools for this massive 1,000-page update.
• The Staggering Cost: Reflecting its status as an elite scholarly research asset, this 1978 masterwork retailed for an incredible 22,000 Yen upon its release, nearly four times the retail cost of the original printing.
• The Missing Publisher Mystery: Unlike the previous edition handled by the mainstream house Shin Jinbutsu Oraisha, the massive size and technical complexity of this 1978 update forced the authors to utilize a specialized printing branch called Tokyo Copy Shuppanbu to get it published without commercial edits.
• Lineage Revisions: This volume features extensive structural modifications to correct generational timelines, adding precise death dates and succession lines for classical headmasters that were completely unknown when the earlier book went to print.

Unusual Facts About the Authors

• A Final Shared Masterpiece: This 1978 expanded directory represents the very last major encyclopedia project that Watatani Kiyoshi and Yamada Tadashi fully compiled and published together as a complete team before Watatani’s health declined.
• The Transition to Strict Academia: While Watatani Kiyoshi began his career writing lighthearted social satire under the alias Tobushi Tahei, the exhaustive, meticulous cross-referencing found throughout this massive 1978 tome proved to the academic community just how deeply serious he had become about martial historiography.
• Preserving Lost Oral Traditions: Throughout the 1970s, Yamada Tadashi traveled directly into deep rural prefectures to interview elderly lineage holders, successfully saving fragile oral records and local family trees just before they were lost to history forever.
