There is evidence of the practice of Kuji for some centuries, but unfortunately we have received few historical documents with reference to all aspects of this exciting practice that was part of the daily work of the Japanese feudal warrior. Thanks to our research, documentation and recovery work, we have been able to translate and revise this famous document written in 1881. Our main purpose is the rescue of these authentic masterpieces, lost and forgotten on the shelves of the old Japanese bookstores. We have made the translation after conducting a thorough review, thus achieving to break the difficult barrier of time and language to make it available to everyone.
