The venue's own site states 'ナッツ不使用' (no nuts used) alongside its gluten-free and dairy-free claims, indicating a structurally nut-free kitchen. No reviews flag nut incidents.
Dairy-free

Verifiably Safe, Either a 100% dedicated kitchen (no allergen on premises) or actively certified by a recognised accreditation body for this allergen.
The kitchen is structurally dairy-free: the venue's own site states '乳製品不使用' (no dairy products used) and a reviewer describes it as a 'completely Gluten-Free and Dairy free kitchen'. Multiple diners flag the venue as 'Good for dairy-free' (11 reports) and the staff offers dairy-free alternatives for drinks.

Vegan
confidence 0.70 ·
Marked menu, shared, Allergen-marked menu and aware staff but shared fryer / prep. Cross-contamination risk acknowledged.
Vegan options are clearly marked on the menu and 'Good vegan options' is the second-most-tagged feature on the aggregator, but the kitchen also serves chicken, beef, pork, and fish (bonito-flake dashi is a base for several dishes), so prep is shared.
Vegetarian

Marked menu, shared, Allergen-marked menu and aware staff but shared fryer / prep. Cross-contamination risk acknowledged.
'Vegetarian options' is one of the most-tagged features on the aggregator, and multiple coeliac diners highlight vegetarian-friendly dishes. The kitchen still serves meat and fish, so the venue is best read as a non-vegetarian kitchen with marked vegetarian options.
Shellfish-free
confidence 0.55 ·
Available on request, No marked menu but staff will accommodate. Quality varies by who is working that shift.
Staff actively accommodated a family's seafood, avocado and oat allergies, with the chef explaining bonito-flake bases and 'double-checking before they finalized our meals.' Only one diner explicitly flagged 'Good for shellfish-free,' so this is best treated as available-on-request rather than a marked or dedicated feature.
Low-FODMAP
confidence 0.40 ·
Available on request, No marked menu but staff will accommodate. Quality varies by who is working that shift.
One coeliac reviewer reports the menu is 'low FODMAP friendly' alongside being entirely gluten-free and dairy-friendly, but no other source corroborates a low-FODMAP protocol.
