You must look specifically for "100% buckwheat" (juwari) soba and confirm there is no wheat in the ingredients. At restaurants, soba is usually wheat-blended and cooked in shared water, so assume it is not safe unless they confirm a 100% buckwheat product.
Brands like Eden Foods 100% Buckwheat Soba and King Soba make certified or all-buckwheat options. Pair with tamari (gluten-free soy sauce) rather than regular soy sauce.

Celiac Safety Glossary
- Gluten
- Gluten is a family of storage proteins (prolamins and glutelins) found naturally in cereal grains like wheat (including varieties like spelt, kamut, and farro), barley, and rye, which acts as a binder to give food elasticity and shape.
- Gluten-free certification
- Gluten-free certification, such as the GFCO (Gluten-Free Certification Organization) seal, verifies that a product contains fewer than 10 parts per million (ppm) of gluten — stricter than the FDA's 20 ppm threshold for "gluten-free" labeling.
