Baiitsu belonged to the Nanga school. This movement looked to Chinese literati traditions for inspiration. His work features a soft brushwork style. He used light washes of colour to build depth. In works like Wild Hawk on a Tree and Egrets in a Lotus Pond, he combined precise observation with a sense of space. He avoided the heavy, dark outlines common in other Japanese styles. Instead, he used subtle ink tones to define form.

The appeal of Baiitsu for modern interiors lies in his use of negative space. His compositions often leave large areas of the paper blank. This creates a sense of calm. His depictions of nature, such as Insects and Grasses, feel immediate. These prints suit minimalist decor. They provide a quiet connection to the natural world without overwhelming a room.
