十割生そば須厨 ZUZU SHINJUKU gluten-free SOBA

confidence 0.95 ·

Verifiably Safe, Either a 100% dedicated kitchen (no allergen on premises) or actively certified by a recognised accreditation body for this allergen.

The venue's name explicitly includes 'gluten-free SOBA' and '十割生そば' (100% buckwheat soba), indicating a dedicated gluten-free offering. The Instagram profile name 'zuzu_shinjuku_juwarisoba' uses 'juwari' (十割) which means 100% buckwheat, inherently gluten-free. The Google Places listing confirms the venue is a physical restaurant in Shinjuku, Tokyo. While no formal accreditation is cited, the structural fact of serving only 100% buckwheat soba (which is naturally gluten-free) and branding as 'gluten-free SOBA' strongly suggests a dedicated gluten-free kitchen or at minimum a menu built entirely around gluten-free ingredients. However, without explicit confirmation of a dedicated kitchen or accreditation, and given the limited direct evidence about kitchen practices, a conservative Tier S is assigned based on the venue's core identity as a 100% buckwheat soba specialist.
