An allergen tool is useful evidence, but its purpose is not a complete vegan ingredient audit.
Use the table for the question it answers
Tully's publishes allergen information for its products. Such information can help identify a listed ingredient that conflicts with a vegan requirement. However, an allergen category list is not automatically an exhaustive account of every animal-derived ingredient or processing step.
Subway Japan's own FAQ provides a direct example of useful recipe evidence: it says the bread uses milk and does not present a dedicated vegetarian or vegan menu. That statement is stronger than an inference from a vegetable filling.
Combine evidence types
Read the current product description, ingredient or allergen material and any explicit dietary policy together. When something remains unclear, ask about the complete dish. Do not label a product vegan simply because one familiar allergen is absent.
For an allergy, follow appropriate current ingredient and cross-contact advice rather than this article's vegan discussion. The two needs overlap but are not interchangeable. A halal enquiry also needs its own evidence. Record which source supports which conclusion so missing information remains visible instead of becoming an invented assurance.
