Works & Achievements
Kozan financed and organized Hokusai's stays in Obuse, commissioning the ceiling paintings for the festival floats (*yatai*) depicting waves and mythological figures. These works, preserved at the Hokusai-kan museum, represent his most spectacular artistic legacy.
Kozan commissioned Hokusai, then eighty-six years old, to create the monumental ceiling composition for the main hall of Ganshoji Temple in Obuse. This Phoenix, spanning twenty-one square meters, is considered one of the master's final masterpieces.
Kozan painted numerous scrolls in the *nanga* style — landscapes, flowers, poetic compositions — attesting to a genuine mastery of the Sino-Japanese literati tradition, now preserved at the Hokusai Museum in Obuse.
His calligraphic output, evidenced by works held in Obuse, reveals accomplished technique in both *kaisho* (regular script) and *sōsho* (cursive script), confirming his standing as a scholar in his own right and not merely a patron.
Beyond his own output, Kozan's lasting achievement lies in establishing an intellectual salon in the provinces, drawing artists, scholars, and political thinkers, and turning Obuse into a recognized cultural and ideological center in late Edo-period Japan.
Anecdotes
In the autumn of 1842, Hokusai, then over eighty years old, made his first journey to Obuse to stay with Takai Kozan. The old master, nearly infirm, rediscovered a surprising creative vitality there, producing works of rare boldness. Kozan had prepared a studio for him and offered generous hospitality to the man whom all of Japan admired.
Kozan commissioned Hokusai to paint the celebrated ceiling panels for the Obuse festival floats (the *yatai*), as well as the great Phoenix on the ceiling of Ganshoji Temple, completed in 1845 when the master was eighty-six years old. These colossal panels — the Phoenix measures twenty-one square metres — rank among Hokusai's last great masterpieces and stand as living testimony to Kozan's patronage.
A fervent supporter of the *sonnō jōi* movement (

Kozan did not hesitate to shelter persecuted political activists in his home. His Obuse residence became a secret gathering place for anti-shogunate thinkers
putting his fortune and his freedom at risk amid growing repression.
A disciple of the painter and intellectual Watanabe Kazan, Kozan was profoundly affected by the arrest of his master during the Bansha no Goku incident of 1839, in which scholars who favored opening Japan to the outside world were persecuted. Watanabe Kazan was forced to take his own life in 1841 — an event that deepened Kozan's imperialist convictions while also urging him toward greater caution.
A wealthy merchant from the town of Obuse in Shinano Province, Kozan devoted a considerable share of his fortune to artistic patronage and his own intellectual cultivation. He studied *nanga* painting, achieved a remarkable mastery of calligraphy, and assembled an extensive library of Chinese and Japanese classics, turning his home into a genuine cultural salon in the mountains of Japan.
