The Tone River in Shimōsa Province (Sōshū Tonegawa), from the series One Thousand Pictures of the Ocean (Chie no umi)

The Tone River in Shimosa Province (Soshu Tonegawa) is a ukiyo-e print by Katsushika Hokusai dated to 1828, drawn from the series One Thousand Pictures of the Ocean (Chie no umi). Held in the collection of the Harvard Art Museums, the design belongs to one of Hokusai's late, water-focused projects, in which he turned his attention to the many faces of Japan's rivers, bays, and coasts. The Tone, one of the largest rivers in the Kanto region, served as a vital artery for trade and travel between the rice-growing plains of Shimosa and the markets of Edo, and Hokusai uses the subject to study working life as much as landscape. Boats heavy with goods or passengers cut through the broad current, fishermen and ferrymen handle ropes and poles, and the riverbank recedes in soft tonal gradations toward distant fields and low hills. The composition demonstrates the qualities that made Edo ukiyo-e so influential abroad: confident diagonal lines, a strong sense of atmospheric depth, and rhythmic patterning in waves and rigging. Printed during a period when Hokusai was sharpening the landscape vocabulary he would soon use in the Thirty-Six Views of Mount Fuji, this Tone River design shows how he treated regional waterways with the same seriousness as celebrated scenic sites. As a documentary ukiyo-e print, the image preserves a particular early nineteenth-century moment when commerce, ritual, and leisure all converged on Japan's inland rivers, and it remains an important reference for understanding Hokusai's mature engagement with water as a subject.
