Kaga Maruimo is a round shaped Japanese yam and the size is about softball. It is known as a high‐end ingredient.

Link with the local area

Farmers started to cultivate the Japanese yam in a paddy field, in which river sand was flowed by the Tedori River flood in 1934. This paddy field began to generate many round shaped yams. The unique condition of the soil -original soil of the paddy field in addition to the river sand‐ is suitable for cultivating large and round shaped Japanese yams.
