Ibuki Soba Buckwheat (Shiga): season, origin and where to buy

Official registration details (MAFF)

The registered description as published by the Ministry of Agriculture, Forestry and Fisheries.

Characteristics

Ibuki Soba is a native variety of buckwheat grown on mountainside fields around Mt. Ibuki. Grain sizes are typically 4.5 mm or smaller in diameter. The seed is surrounded by a seed coat, which takes up a considerable proportion of the grain and is responsible for the green tone and strong flavor of this soba. The soba is rated highly by soba mills and soba noodle restaurants for its excellent umami and sweetness.

Link with the production area

Local conditions in areas upstream of the river Anegawa (Ane River), where Ibuki Soba production originated, are favorable for the production of soba. Sloping mountainside locations are well-drained, and chances of cross-pollination are reduced by the surrounding mountains. Production has gradually spread downstream to include parts of Maibara City, where well-drained alluvial landforms, and andosol soils also make good soba fields. Seeds are, as a rule, still collected from fields upstream of Anegawa to preserve the integrity of the native breed, while expanding areas of production downstream has ensured more consistent yields.
