His style is defined by a mix of realism and bold ink washes. In works like Monkey on a Rock and Snails, Rosetsu captures animals with a sense of humour and personality. He often placed subjects in unusual positions or used extreme perspectives. His ink paintings use negative space to create atmosphere. This is visible in Moonlit Landscape and Mountains and Distant Boats. He balanced the small details of Sparrows in a Plum Tree with broad, fast strokes.

Modern collectors value Rosetsu for his playful and eccentric vision. His depictions of animals, particularly his famous paintings of puppies, feel modern because of their charm. These prints bring a sense of character to a room without being overly formal. His use of monochrome ink and grey tones fits well with contemporary interiors. The work offers a connection to the Edo period through a lens of individual expression rather than rigid tradition.
