Naitō Takaharu

Who They Were

Naitō Takaharu (内藤高治, ないとう たかはる) was a Japanese samurai and swordfighter active from the late Edo period into the early twentieth century. He was born on 16 December 1862 in Mito Domain, a feudal domain centred on present-day Ibaraki Prefecture, and died on 9 April 1929 in Kyoto. His birth fell in the second year of the Bunkyū era (文久), a brief nengō that ran during the final years of the Edo period (1603–1868).

Naitō was a swordsman of the Hokushin Ittō-ryū, a school of kenjutsu founded in the early nineteenth century. He spent much of his career teaching kendo, the modern martial art derived from traditional swordsmanship, to the Japanese police force. He also served as the first teacher at the Budo Senmon Gakko, a specialist school for martial arts training.

Life and Career

Details of Naitō’s early life in Mito Domain are sparse, but his training in the Hokushin Ittō-ryū placed him within a lineage that emphasised practical combat technique and rigorous sparring. The school was known for its systematic approach to swordwork, and Naitō’s mastery of it eventually brought him to the attention of the Tokyo Metropolitan Police Board, which employed him as an instructor. The police force had adopted kendo as a core part of officer training in the Meiji period, and Naitō became one of its most prominent teachers.

His reputation grew beyond the police force when he was appointed the first instructor at the Budo Senmon Gakko, a school established to train martial arts teachers and practitioners. In this role, Naitō helped shape the curriculum for a generation of kendo instructors. He also contributed to the creation of the Dai Nihon Teikoku Kendo Kata, a set of formal exercises designed to standardise kendo practice. This work was carried out under the auspices of the Dai Nippon Butoku Kai, an organisation founded in 1895 to promote and regulate the martial arts across Japan. Through this body, Naitō helped promulgate kendo in schools and universities, making the practice a standard part of Japanese education.

One of the most famous recorded episodes of Naitō’s career involves a match with Takano Sazaburo, another leading kendo figure of the era. According to contemporary accounts, Naitō did not strike a single blow during the contest. Takano repeatedly hit him on the kote (小手, wrist guard) and the men (面, protective helmet). Despite this, the judges ruled that Naitō displayed superior swordsmanship. His calm reception of Takano’s attacks, without any sign of concern, was taken as evidence of a higher level of skill — an ability rooted in his command of kiai (気合, the focused shout used to unnerve an opponent and unify mind and body). The match became a celebrated demonstration of the principle that kendo was not merely about landing blows but about controlling the encounter through composure and intent.

Why They Matter

Naitō Takaharu matters because he stood at the bridge between two eras of Japanese swordsmanship. Born a samurai in the Edo period, he lived through the Meiji Restoration and the transformation of the warrior arts into modern disciplines. His work with the Tokyo Metropolitan Police Board and the Budo Senmon Gakko institutionalised kendo at a time when the practice risked being discarded as obsolete. The Dai Nihon Teikoku Kendo Kata, which he helped create, provided a standardised framework that allowed kendo to be taught consistently in schools and universities.

His match with Takano Sazaburo also matters for what it reveals about the values of kendo. The judges’ decision to award victory to a man who never landed a blow underscored the martial art’s emphasis on spiritual and psychological dominance over mere physical contact. Naitō’s use of kiai was not a theatrical flourish but a core technique, one that could decide a contest before a single strike was exchanged. In this, he embodied the ideal of the swordsman as much more than a fighter.

The Name in Japanese

The name is written 内藤高治 in kanji.

• Kana reading: ないとう たかはる
• Romaji: Naitō Takaharu

The family name, 内藤, is read ないとう (Naitō). It is composed of two characters:

• 内 (ない, nai) — meaning “inside” or “within.” This character also appears in words like 国内 (こくない, domestic) and 内部 (ないぶ, interior).
• 藤 (とう, tō) — meaning “wisteria.” This character is common in Japanese surnames, often indicating descent from the Fujiwara clan, whose name shares the same 藤 character.

The given name, 高治, is read たかはる (Takaharu). It is composed of two characters:

• 高 (たか, taka) — meaning “tall,” “high,” or “noble.” This character appears in words like 高い (たかい, expensive or high) and 高校 (こうこう, high school).
• 治 (はる, haru) — meaning “to govern,” “to rule,” or “to heal.” This character appears in words like 政治 (せいじ, politics) and 治療 (ちりょう, medical treatment). In names, it is often read as haru or ji.

Taken together, the name suggests something like “noble governance within the wisteria,” though such readings are interpretive rather than fixed. The characters were chosen by Naitō’s family, and their meanings would have been understood in the context of samurai naming conventions, where auspicious or virtuous characters were preferred.

Legacy

Naitō’s legacy survives primarily through the institutions he helped build. The Budo Senmon Gakko, where he was the first teacher, became a model for later martial arts academies. The Dai Nihon Teikoku Kendo Kata remained a central part of kendo practice for decades, and its influence persists in the kata forms still taught today. His work with the Dai Nippon Butoku Kai helped ensure that kendo would be a fixture of Japanese education, a position it held until the end of the Second World War and which was later revived in modified form.

The match with Takano Sazaburo also became part of kendo’s oral tradition, cited by instructors to illustrate the importance of kiai and composure. Naitō’s victory without a single strike remains a striking example of the art’s deeper principles. He died in Kyoto on 9 April 1929, but his name is still remembered among practitioners of kendo, particularly those who study the history of the police and educational traditions of the martial art.
