How to Say ‘Shellfish allergy’ in Japanese

甲殻類のアレルギー

koukaku rui no arerugii

[KOH-kah-koo ROO-ee noh a-lehr-GEE]

💬 Usage Tip: 甲殻類 (kōkakurui) covers crustaceans like shrimp and crab only, not clams or oysters. For those, say 貝類 (kairui) "shellfish such as clams".

🇯🇵 In Japan: Shrimp and crab are on Japan's legally required food-allergen labeling list, so restaurant staff will recognize 甲殻類 immediately.
