Inashiki: Yokotone River

About location

The Yokotone River is best known within Ibaraki Prefecture for the Yokotone Sluice Gate, a historic structure completed in 1921 to regulate water between the river and the Tone River. The waterway belongs to the Tone River system and runs through the low, intensively cultivated plain of Inashiki, where paddy fields, drainage channels and compact riverside settlements shape the land. Inashiki lies beside Lake Kasumigaura, Japan’s second-largest lake, whose basin has long influenced local farming and transport. The sluice gate is designated an Important Cultural Property of Japan, preserving a reminder of the engineering used to manage water levels across this broad lowland.

City Inashiki

Built around lowland settlements between Lake Kasumigaura and the Tone River, Inashiki grew into a modern rural city in southeastern Ibaraki Prefecture. Its broad, level terrain is shaped by rice fields, waterways and the seasonal rhythms of agriculture, while the lake is part of Japan’s second-largest lake system. The area is also known for Edozaki kabocha, a locally grown squash prized for its sweetness. Inashiki provides a quieter perspective on the Kantō Plain beyond Tokyo’s urban edge.

Ibaraki Prefecture
Region Ibaraki Prefecture

Ibaraki Prefecture has served as an administrative and agricultural heartland within eastern Japan since the Edo period. Spreading across the northeastern Kantō Plain, it meets the Pacific Ocean to the east and is shaped inland by Lake Kasumigaura, Japan’s second-largest lake. Mount Tsukuba, with its two distinctive summits, is a defining landmark west of the lake. The prefectural capital, Mito, was the seat of a Tokugawa branch domain; its Kairakuen garden was created in 1841 by Tokugawa Nariaki and is celebrated for its plum groves. Agriculture remains central, from rice fields to melon cultivation, while the coast adds fishing ports and broad beaches.
