Is Ichiran Ramen Gluten Free?
No — Ichiran ramen is not gluten free. The noodles are made from wheat flour, and the signature tare seasoning contains wheat-based soy sauce. There is no certified gluten-free option at any Ichiran location in Japan.

Why Ichiran Is Not Gluten Free
Wheat noodles
Ichiran's straight, thin noodles are made from wheat flour — the primary ingredient. There is no rice noodle or konjac substitute available. The noodles cannot be omitted from the standard order.
Tare (secret red sauce)
Ichiran's signature spicy red tare — the key to their flavor — is blended into every bowl. This sauce contains soy sauce made with wheat. Requesting "no tare" is possible but removes the core flavor and still does not address the noodle issue.
Cross-contamination risk
Ichiran is a high-volume ramen chain. The kitchen processes hundreds of wheat noodle bowls per day. Even if you could remove the tare, cross-contamination from cooking water, utensils, and surfaces makes it unsafe for anyone with celiac disease.
What About the Tonkotsu Broth?
Ichiran's tonkotsu broth is made by simmering pork bones for many hours. Tonkotsu broth by itself is naturally gluten-free. However, Ichiran combines the broth with the tare (soy-based seasoning) before serving, making the final soup unsafe. Ordering a "light seasoning" bowl reduces — but does not eliminate — the wheat content.

If you're traveling with someone who has celiac disease and others who don't, consider splitting up at a ramen stop: celiacs can visit Afuri while the rest of the group tries Ichiran nearby. Both are in Shibuya.
For non-celiac gluten sensitivity (NCGS) travelers who can tolerate small amounts: requesting no tare reduces wheat significantly, but the noodles remain. This is still not recommended for anyone with diagnosed celiac disease.
