His technique follows the suiboku-ga tradition, influenced by the Chinese monk Mokkei. Sōami avoided the sharp, jagged lines common in earlier Muromachi period works. Instead, he used soft ink tones to create a sense of atmosphere and distance. In Landscape of the Four Seasons, his brushwork suggests forms through mist and light rather than hard outlines. This method allows the viewer to observe the natural world through quiet observation.

The appeal of Sōami's work lies in its restraint. These monochrome ink paintings provide a sense of calm that suits modern interiors. His compositions, such as Gazing at a Waterfall, use empty space to balance the subject matter. Collectors value these prints for their ability to bring a meditative quality into a room. The lack of bright colour ensures that the focus remains on the texture of the ink and the movement of the water.
