Wataru Takahashi mainly focuses on Fixed point, Pure mathematics, Hilbert space, Mathematical analysis and Discrete mathematics. His biological study spans a wide range of topics, including Monotone polygon, Weak convergence, Fixed-point theorem, Variational inequality and Lipschitz continuity. In the subject of general Pure mathematics, his work in Banach space is often linked to Theoretical computer science, thereby combining diverse domains of study.

His Banach space study incorporates themes from Type, Combinatorics and Resolvent. His research investigates the connection between Hilbert space and topics such as Monotonic function that intersect with problems in Limit of a sequence, Convex function and Semigroup. Wataru Takahashi frequently studies issues relating to Iterative method and Mathematical analysis.
