Kaga lotus root

Kaga renkon is a lotus root grown in the Kanazawa area and counted among the city’s fifteen Kaga vegetables. The name is grounded in real fields: the former Kosaka village area, Morimoto, Yakushidani, Saida, and the reclaimed land of Kahokugata.

Those places also mark different ways of working. Kosaka-area roots are associated with hoe digging and mud attached to the harvest, while Kahokugata fields are linked with water digging that uses irrigation water. Together, the districts give Kaga renkon its concrete map: sticky soil, water channels, thick roots, and producers working across several Kanazawa-area growing zones.

Descriptions of Kaga renkon fields often begin with the soil. In Kanazawa, many paddies are so sticky that once a person steps in, pulling a foot back out can be difficult. For the people harvesting the roots, that condition is not scenery; it is the resistance felt in every movement through mud.

Clear Hokuriku water and a rainy climate are also part of the cultivation setting. The point is practical as much as atmospheric: drained muddy fields support hoe digging, while flooded fields and managed water allow water digging. The landscape becomes visible through the method used to bring each root out without damage.

Local accounts trace lotus-root cultivation in Ishikawa back to the Kaga domain period, with accounts involving the fifth lord, Maeda Tsunanori. Later, cultivation took hold around Ohi-machi in Kanazawa, part of the Kosaka area, and the root came to be called Ohi renkon.

In the Meiji 20s, the root gained attention as food and as a market crop, and the name Kosaka renkon appeared. By the middle of the Taisho period, Motooka Daikichi, remembered for expanding production, shipped it under the name Kaga renkon. The current name carries that route from castle-era accounts to Ohi fields, Kosaka fields, and market shipments.

Hoe digging takes place after water is drained from the muddy field. Producers enter the mud and use a hoe to free the buried lotus root, working carefully because a blade in the soil can scar the root. Kosaka, Morimoto, and Yakushidani are described with this method, and mud attached to the harvested root remains part of the Kosaka image.

Water digging works differently. In a flooded field, water from a hose loosens the soil by pressure and helps expose the root. Kahokugata is strongly associated with this method. In colder months, harvesters still enter water that can rise above the knee, using pressure, touch, and experience to find the rhizome in the mud.

Kaga renkon is described through texture as much as place. It is rich in starch, strongly sticky, thick-fleshed, and short between nodes. The tip has a crisp bite, while the base becomes mochi-like; that difference along one root gives cooks several textures to work with.

The grated root is central to hasu-mushi, a Kanazawa dish that relies on sticky grated lotus root. Middle-to-tip sections are described as suited to simmered dishes, lotus-root soup, and grating, while the firmer base suits stir-fried dishes such as kinpira. The cooking logic begins inside the root itself, section by section.

Kaga renkon ships broadly from August to May, carrying the Kanazawa lotus-root season from late summer into spring. A description of the 2010 crop year lists the JA Kanazawa lotus-root producer group at fifty producers, with 34.4 hectares under cultivation across hoe-dug and water-dug fields and 252 tons produced; those figures describe that year’s scale, not a current total.

The work continues after harvest. Roots are sorted into detailed grades, and producers discuss soil and fertilizer management as part of maintaining the characteristic stickiness. The Kosaka Renkon Preservation Association also keeps attention on hoe-dug, mud-attached Kosaka renkon, linking the place name with muddy fields and hand work.
