Ask before you reserve
Use the operator's message function before booking. State the ingredient or food group, whether trace contact is a concern, and whether the restriction is an allergy, medical need, religious practice, vegetarian preference or another requirement. Ask what substitutions are possible, whether every stop can be checked, and whether the operator can confirm the plan in writing.
Do not rely on a dish name or translated menu alone. Stocks, sauces, marinades, shared fryers and preparation surfaces can contain ingredients that are not obvious from a short description. Tokyo's public-health resource explains food-allergy considerations, while the official Tokyo travel guide links to current vegetarian and vegan resources. Those resources support planning; they do not certify a particular tour kitchen.
What the checked listings say
The Shibuya and Shinjuku listings specifically ask guests to tell the operator about allergies or dietary restrictions in advance. Neither statement promises that every restriction can be accommodated. The Asakusa listing describes included tastings and says the food may change with the season; the captured details do not describe an allergy process. Treat that as unknown and ask directly.
Alcohol is part of the Shibuya and Shinjuku listings' drink descriptions. Shibuya says alcoholic drinks are served only to travelers aged 20 or older. Ask which drink alternatives are available if you do not drink, and confirm the age rules for every traveler.
When to skip the tour
If the operator cannot explain how each stop handles your particular risk, do not assume that you can safely avoid a dish once the group arrives. A self-guided route lets you choose each venue and ask about ingredients one at a time. You can also book a tour only after the supplier confirms the restrictions you raised. This page is practical planning information, not medical advice.
For more context, compare the three neighborhood formats and check where each group meets. Reconfirm menus and restrictions with the supplier shortly before your date because tasting selections can change.
Common questions
Can these tours guarantee that every allergy can be accommodated?
No. The Shibuya and Shinjuku listings ask guests to disclose dietary needs in advance, but neither promises that every restriction can be accommodated. Ask the operator about every stop and skip the tour if it cannot address your specific risk.
Is alcohol served on the Shibuya tour?
The listing describes alcoholic drinks and says they are served only to travelers aged 20 or older. Ask the operator what alternatives are available if you do not drink.
