Kengiro Azuma was born the second son of seven brothers on March 12th 1926 in the small town of Yamagata in northern Japan. His father and his grandfather were artisans who worked in bronze. 


In 1943 he joined the navy flying corps in the Maizuru division but in 1946, after the United States destroyed Hiroshima and Nagasaki with atom bombs forcing the Japanese to surrender, he returned to his hometown and his studies at the lyceum. The Emperor was no longer a divinity, Japan was going through a deep economic crisis during which the system of values definitively collapsed. Azuma found no comfort in religion or in the town where he grew up, and thus chose art to give him a new sense to life. He wrote: “I thought that I could find myself in art, serenity and a reason to live, joining the search for new with past; the history of my family without cutting ties or roots. Aesthetic research and beauty, the search for perfection could have substituted the ancient certainties that fell in the face of reality, fomenting the reason for the great question: what does it mean to live?” 


In 1949 Azuma enrolled at the National Art and Music University Gedai in Tokyo from where he graduated in 1953, and afterwards studied for two year in post-graduate courses. He left for Milan in 1956 and enrolled at the Brera Academy of Fine Arts motivated by the conviction that that was the right path to take in order to become an artist, the economic difficulties and the numerous questions about his origins, the meaning of life and himself notwithstanding. In 1958 he participated in the Terza mostra nazionale d'arte giovanile (the Third National Exhibition of Young Art) at the Palazzo delle Esposizioni in Rome. In 1960 he graduated from the Brera Academy of Fine Arts and became the personal assistant of the artist Marino Marini, who sometimes told him: “Azuma, remember that you are Japanese…”.

In that year he decided to empty his studio of all the work he had created until then and begin a quest all his own that had its roots in an “unconstructed beauty, something that can only be felt by a Japanese; iron that is rusting, a house that is falling apart, the invisible element that is behind material, the full and the empty…” These reflections on the meaning of infinity and the life cycle brought him to the realization of his first bas-reliefs entitled MU. His first one-man exhibition was inaugurated at the Galleria Minima in Milan and diverse one-man exhibitions followed, among which is one at the Palazzo Strozzi in Venice and at the Galleria l'Obelisco in Rome in 1962, and at the Galleria Il Cavallino in Venice. Several prizes follow in 1963: the National Museum of Modern Art Award for his sculpture MU-99, the Emile Godar Prize for the MU-52 sculpture during the Concorso Internazionale di Scultura at La Sarraz (The International Sculpture Contest…) in Switzerland and second prize at Quinto Concorso Internazionale di Scultura (the Fifth International Contest for Sculpture) in Padua with the MU-89 sculpture. 


In 1964 Kengiro Azuma met the gallery owner Bruno Lorenzelli in his studio, and from this meeting they developed a long lasting friendship. In 1965 the artist is invited to the International Symposium of Sculpture at California State University where he installed MU-464 and participated in a group show entitled Japanese New Paintings and Sculptures at the San Francisco Museum of Art, which travelled to seven other American museums among which were the Museum of Modern Art in New York City. He had a one-man show at Toninelli Arte in 1966 and in 1968 he won second prize in the Dalmine Forma in Tubi (Dalmine Form in Tubes) competition. In 1971 he took part in the Simposio Internazionale di Scultura (Intedrnational Sculpture Symposium) at St. Margarethen with the installation Cielo Terra e Uomo (Sky, Earth and Man). Aldo Tagliferri wrote: “Cielo Terra e Uomo is Azuma's cosmos; a circumscribed fantasy world in which man loses the sense of his limits and places himself in relationship to a reality of which he is an integral part(…)”. In the same year his work Croce (Cross), originally created for the Franciscan Monastery at Sion, is placed in the collection of the Vatican Museums in Rome by Pope Paul VI himself . In 1972 he took part in an itinerant collective exhibition in Japan and in 1974 a one-man exhibition of his is presented in the museums of Tokyo, Yamagata and Osaka. In 1977 he returned to exhibit at Vatican Museums with his Folgorazione di San Paolo (The Conversion of Saint Paul).

In 1998 he created an expository walk and installation, that became a permanent installation, entitled Il Sogno (The Dream) at La Marrana in Montemarcello, Ameglia of which Rossana Bossaglia wrote: “[…] he has always believed that there is no contrast between nature and art; quite to the contrary, that, in fact, there exists a correspondence, even a symbiosis, between the two. The series of installations that he created at Marrana suggests a specific path for the visitor as if he or she was dealing with an action that was unfolds in a temporal succession […]”. 


In 1999 the artist was nominated visiting professor at the National University of Art in Tokyo and took part in a collective exhibition at Palazzo Reale in Milan entitled Arte per Assisi (Art for Assisi) and had a one-person exhibition called La Luce di Teglio at Palazzo Besta in Teglio.
