What to ask first
Japanese restaurant allergy questions should separate the noodle, broth, tare, batter, fryer, garnish, and sauce. Dashi usually means fish-based stock, so a dish that looks vegetarian may still use fish unless the kitchen confirms otherwise.
Soba needs a direct buckwheat question. Some noodles are 100 percent buckwheat, some are mixed with wheat, and some kitchens cook different noodles in nearby or shared water.

Where those allergens may appear
Soba and noodles

Dashi and broths
Ask about bonito, dried fish, kelp blends with fish, seafood stock, miso, soy sauce, and broth bases prepared before service.
Tempura and fried items
Ask about wheat batter, egg, shellfish, fish, and whether tempura shares fryer oil with other items.

How to ask without guessing

For fish or shellfish allergy, ask whether dashi, tare, broth, curry, or sauce contains bonito, dried fish, seafood stock, shrimp, crab, or oyster.
