Master Funakoshi’s Very First Tokyo Student

In the spring of 1922, Master Gichin Funakoshi traveled from Okinawa to Tokyo to demonstrate Okinawan Tōde (Karate-jutsu) at the First National Physical Education Exhibition organized by the Ministry of Education at the Tokyo Higher Normal School (now University of Tsukuba).

Among the distinguished attendees was Hoan Kosugi (小杉 放庵, 1881 – April 16, 1964; birth name Kunitarō Kosugi), an acclaimed Western-style and Nihonga painter, poet, and cultural figure. Captivated by the grace, profound martial precision, and spiritual dignity of Funakoshi's demonstration, Kosugi approached the Okinawan master immediately and asked to become his student.

With that historic meeting, Hoan Kosugi became Gichin Funakoshi's very first registered karate pupil on the Japanese mainland.

The Tabata Poplar Club and Early Tokyo Training

At the time, Hoan Kosugi served as president of the Tabata Poplar Club (田端ポプラ倶楽部), an influential Bohemian salon located in the artists' quarter of Tabata in northern Tokyo. The Poplar Club gathered leading painters, sculptors, writers, and intellectuals who combined artistic experimentation with physical recreation, including tennis and martial arts.

Kosugi invited Master Funakoshi to use the Poplar Club grounds and facilities to teach karate to club members and curious scholars. This salon environment provided Master Funakoshi with crucial early social legitimacy in Tokyo’s intellectual circles at a time when Okinawan arts were largely unknown on the mainland.

The Birth of Karate’s First Modern Book: Ryūkyū Kenpō Karate

Beyond personal training, Hoan Kosugi played an indispensable historical role in convincing Master Funakoshi to document his art in writing. Kosugi told Funakoshi that if karate remained an oral secret confined to memory, it risked misinterpretation or extinction. He pledged full artistic and publishing assistance if the master would author a definitive textbook.

Funakoshi agreed, and in November 1922, the pioneering volume Ryūkyū Kenpō Karate (琉球拳法 唐手) was published in Tokyo by Bukyōsha. It was the first book on karate ever published in modern history.

The Conception of the Shotokan Tiger (Tora no Maki)

To accompany Master Funakoshi's groundbreaking text, Hoan Kosugi brushed an original watercolor and sumi-e illustration: a crouching tiger enclosed within a circular dynamic border, tail rising coiled in poised vigilance.

The emblem carried multifaceted layers of classical symbolism:

1. Tora no Maki (虎の巻 - The Tiger Scroll): In Japanese cultural tradition, the phrase tora no maki designates the sacred scroll or foundational primer of martial strategy, derived from the classical Chinese military treatises of Sun Tzu and the Six Secret Teachings (Rikuto).
2. Quiet Strength and Vigilance: The tiger does not roar or lunge recklessly; it crouches with coiled tension, calm, silent, and watchful. This visual metaphor directly mirrored Funakoshi's foundational precept: Karate ni sente nashi ("There is no first strike in karate").
3. The Circular Border: The unending circle symbolizes spiritual wholeness, the void (kara), and mutual respect (rei), restraining raw physical ferocity within ethical bounds.

Kosugi’s tiger design appeared prominently on the cover and frontispiece of Funakoshi’s publications and later became the universal insignia of the Shotokan school worldwide.

Legacy and Friendship

Hoan Kosugi remained a devoted supporter and lifelong friend of Master Funakoshi. Even as karate expanded into major university dojos (Keio, Waseda, Chuo, Takushoku) and later saw the formal founding of Nihon Karate-do Shotokai, Kosugi’s initial leap of faith in 1922 provided the catalyst that introduced karate-do to Japan and the world.
