7In the late 1980s and early 1990s, Grandmaster Masaaki Hatsumi, inheritor of nine martial arts schools and a lineage spanning over 1,000 years, authored a series of newsletters to serve as a useful guide and reference for maturing martial arts students around the world. The articles contained within Tetsuzan ("Iron Mountain") are diverse: interviews with "The Last Combat Ninja" Soke Toshitsugu Takamatsu, the symbolic back-story of the TV show Jiraiya, examples of utilizing exotic ninja weapons and techniques, and, perhaps most aptly, the importance of correctly studying the Bujinkan basics. Containing a wealth of illustrated information, enlightening interviews and historical insights, Tetsuzan is as relevant for understanding true Budo today as it was during the era of its original publication. In the subtleties of the writing, an underlying timeless constant can be found, guiding all martial artists onto the true path of the Bushi.
