He was a major developer in particular of the theory of discontinuous groups for non-Riemannian homogeneous spaces and the theory of discrete breaking symmetry in unitary representation theory. He has been a member of the Science Council of Japan since 2006, Board of Trustees of the Mathematical Society of Japan (2003–2007), the Editor in Chief of the Journal of the Mathematical Society of Japan (2002–2006), and currently is the Managing Editor of the Japanese Journal of Mathematics since 2006.

He was a leading member of the Japanese school of homotopy theory, following in the tradition of Hiroshi Toda. Nishida received his Ph.D. from Kyoto University in 1973, after spending the 1971–72 academic year at the University of Manchester in England. He then became a professor at Kyoto University in 1990. His proof in 1973 of Michael Barratt's conjecture (that positive-degree elements in the stable homotopy ring of spheres are nilpotent) was a major breakthrough: following Frank Adams' solution of the Hopf invariant one problem, it marked the beginning of a new global understanding of algebraic topology. His contributions to the field were celebrated in 2003 at the NishidaFest in Kinosaki, followed by a satellite conference at the Nagoya Institute of Technology; the proceedings were published in Geometry and Topology's monograph series. In 2000 he was the leading organizer for a concentration year at the Japan–US Mathematics Institute at Johns Hopkins University. Nishida's earliest work grew out of the study of infinite loop spaces; his first paper (in 1968, on what came eventually to be known as the Nishida relations) accounts for interactions between Steenrod operations and Kudo–Araki (Dyer–Lashof) operations. Some of his later work concerns a circle of ideas surrounding the Segal conjecture, transfer homomorphisms, and stable splittings of classifying spaces of groups. The ideas in this series of papers have by now grown into a rich subfield of homotopy theory; it continues today in (for example) the theory of p-compact groups.

He was a professor at Kyoto University. Alongside Wolfgang Krull, Oscar Zariski, and Masayoshi Nagata, he is famous for his early work in commutative algebra. In particular, he is most well known in helping to demonstrate Akizuki–Hopkins–Levitzki theorem.
