CENTENARY OF “RENTAN GOSHIN KARATE-JUTSU” (1925)
2025 marks the centenary of the publication of the second volume written by master Gichin Funakoshi, entitled 錬膽護身唐手術 (Rentan Goshin Karate-Jutsu), which can be translated as “Temper your courage and defend yourself with the art of Karate”. The first edition was printed on March 1, 1925, and was officially published on March 14 of the same year. The cover price at the time was just under three yen.
This work represents a revised and enriched version of his first book, 琉球拳法唐手 (Ryūkyū Kenpō: Karate), published in 1922. While in that initial edition the techniques were illustrated through stylized drawings painted by the artist Kosugi Hōan, in the new volume these illustrations were replaced by photographs portraying Funakoshi himself while performing the techniques and kata, lending greater realism and clarity to the work.
In terms of content, the technical layout remains essentially unchanged from the previous book, except for the exclusion of two throwing techniques: 跛倒 (Bikkodaoshi), which can be translated as “flipping the lame”, and 腕倒 (Udedaoshi), or “folding one's arms” or “bending the shoulder”, which do not appear in the new edition.
As for the master's family origins, Gichin Funakoshi belonged to one of the lower ranks (筑登之, Chikudun) of the 士族 (Shizoku) class, the ancient warrior aristocracy. His family descended from a branch of the far more illustrious 山田 (Yamada) lineage, belonging to the Shizoku nobility of Tomari village (泊士族).
In addition to being a martial art master, Funakoshi was first and foremost a scholastic educator, trained also in the studies of Chinese classics, an aspect that also shines through in his Rentan Goshin Karate-Jutsu. In one of the pages of the volume, in fact, three calligraphic works appear, each accompanied by an aphorism, emphasizing the ethical-philosophical dimension of the Karate he taught.
At the top we find 無手人行拳 / mute jin kōken - “The weaponless man is travelling with the fist“
The phrase originates from “The Quiet Hermitage“, an ancient Chinese collection of Zen Buddhist kōans (a 公案 / kōan is a riddle, problem or story passed down by ancient Zen masters, which is offered to a student to open his eyes to a truth of Zen), compiled in 1224. Here the term “fist” can be seen as the martial art of Karate, which in the above sentence is associated with a traveling utensil (therefore useful and important). In this context, the Zen saying emphasizes the ideal of the wayfarer who travels through life relying only on his own inner discipline, represented by the fist (the martial art). It is a concept deeply rooted in Zen thought: true strength comes not from what one possesses, but from what one is.
This aphorism will be hung, 15 years later, also inside the Shōtōkan dōjō, and will appear in many photos of the dōjō of the time.
On the left we find 先正其心 / mazu tadase sono kokoro - “First of all, correct (rectify) his heart“
This aphorism comes from Confucian thought, and appears particularly in texts such as the Daxue (大學 / The Great Wisdom), one of the four classic books of Confucianism. In that text, there is a logical and moral sequence that guides self-cultivation: “He who wishes to rectify his heart, must first make his intention sincere; to make the intention sincere, he must first deepen his knowledge; and knowledge begins with the study of things“.
Therefore, “rectifying the heart“ means purifying one's intentions, appeasing disordered passions, removing selfishness and ego, and aligning one's mind with the right path (道 / dō).
In the art of Karate, physical training is always accompanied by mental and spiritual discipline. Correcting one's “kokoro“ (heart/mind) is essential before one can learn a technique or use it correctly: a disturbed heart generates impulsive actions, a “centered“ (righteous) heart is ready, lucid, right.
For this reason, in Budō, instruction starts precisely from attitude, respect and self-control (心術 / shin-jutsu) - long before physical skills (技術 / gi-jutsu).
On the right we find 妙入神 / myō nyūshin - “(Acquiring) the 妙 / secret (of the art) one 入 / enters the (level of) 神 / divine”
In his works, master Funakoshi often uses the term 妙 / myō (secret), when speaking about the art of Karate. For example, in “Ryūkyū Kenpō: Karate“ (1922), Funakoshi writes:
“It has been said since ancient times that the secret (妙 / myō) of Karate lies in the ability to contract and expand (伸縮 / shinshuku) both hands/arms together, and, indeed, kisei (奇正) and In/Yō (陰陽) are the true value (妙諦 / myōtei, i.e. cardinal principle, key to understanding) of Karate-Jutsu“.
But of course, in this context, the aphorism is used to describe the highest stage of mastery, where technique is no longer merely performed - it is transcended. One no longer fights with force, nor paints with technique: the action flows as if originating from a higher source.
妙 (myō) is the stage of finest mastery,
神 (shin) is the stage of supernatural intuition, the “kami no waza” - an ability that goes beyond the human.
In Zen Buddhism, the term 妙 often appears with the meaning of “ineffable depth” - that which can only be directly realized, not explained. 神 itself is understood as pure spontaneity, free from attachment or effort. Thus the aphorism 妙入神 is also a description of satori, Zen enlightenment through lived practice: art becomes spirit, and action becomes revelation.
