What to try
- Mentaiko pasta: seasoned pollock roe with butter or cream, often topped with nori and shiso.
- Japanese mushroom pasta: shiitake, maitake, or shimeji with soy-butter seasoning.

Ordering
Look for 和風 (Japanese style), 明太子 (seasoned spicy pollock roe), たらこ (salted pollock roe), 大葉 (shiso), きのこ (mushrooms), and 大盛り (larger portion, usually extra). Wafu pasta appears at specialist shops, family restaurants, cafes, and shopping centers. Forks are standard, though some Japanese-style chains offer chopsticks.
Allergy caution
Pasta commonly contains wheat and egg. Mentaiko, butter, cream, cheese, and dashi may add fish roe, dairy, fish, or soy. Japan’s Consumer Affairs Agency warns that restaurant meals can involve unintended cross-contact and that allergy information is not displayed everywhere. With a severe allergy, contact the restaurant before visiting and ask about ingredients and shared equipment.

Is mushroom pasta vegetarian?
Not necessarily; the sauce may contain fish-based dashi, butter, or cheese.
What is the difference between mentaiko and tarako?
Both are pollock roe. Mentaiko is generally seasoned with chili, while tarako is primarily salt-cured.
