Nambata’s early works include large sequential compositions executed in a picture-scroll format, including The Mole’s Path (1963), an eleven-sheet work, and Ivan the Fool (1964), a six-scene composition across two sheets. His imagery incorporates human, animal, plant and architectural forms, often reduced to ambiguous, symbolic figures. From 1967, Nambata’s lines and colours became increasingly fluid and expressive, while his Sun Series of tempera works developed the relationship between colour and form. He also produced works in which fine pen lines and washes of colour create fantastical spaces, with recurring motifs including the sea, sky, sun, figures and imagined worlds.
In 1965, Nambata entered Waseda University’s First Faculty of Letters, where he studied art, graduating in 1970. His first solo exhibition was held at Dainana Gallery, Tokyo, in 1967, and he was selected for the Shin-ei Sembatsu Exhibition at Mitsukoshi in 1971, 1972 and 1973, including works in watercolour and oil.
Nambata died in an accident in January 1974, aged 32. More than 2,000 oils, watercolours and drawings were left at the time of his death, and his work has continued to be exhibited posthumously in Japan. Works by Nambata are held in the collections of the Tokyo National Museum of Modern Art, Setagaya Art Museum, Tokyo Opera City Art Gallery, Niigata Prefectural Museum of Modern Art and Okawa Museum of Art.
