Is Itsu Halal?

Is Itsu Halal?

Itsu is a UK-based Japanese food brand founded by Julian Metcalfe (co-founder of Pret a Manger). The brand operates restaurant chains across the UK and sells a supermarket grocery range stocked in Tesco, Sainsbury’s, Waitrose, and other major retailers. The range includes sushi, gyoza, miso soup, rice noodle soups, seaweed snacks, and ready meals.

The halal status of Itsu varies by product and by whether you are eating at a restaurant or buying from a supermarket shelf.

The Mirin and Sake Problem

The primary halal concern with Itsu supermarket products is not meat — it is alcohol in cooking condiments:

• Mirin is a sweet Japanese rice wine used extensively in Japanese cooking as a glaze and flavour enhancer. It contains residual alcohol (typically 8–14% ABV before cooking, with trace amounts remaining after cooking). Mirin appears in several Itsu sauces, marinades, and ready-meal components.
• Sake (Japanese rice wine) is sometimes used in marinades and cooking sauces in Japanese cuisine. Itsu products do not prominently advertise sake in their ingredients, but natural flavourings or cooking wines listed may include it.
• Dashi — traditional Japanese stock made from kombu seaweed and bonito (dried tuna flakes) — does not contain alcohol but is used in many Itsu products. Dashi is not a halal concern on its own, but some dashi-flavoured products may combine with mirin in the same recipe.

The key question to ask: does the specific Itsu product contain mirin or any cooking wine? Check the ingredients panel on each product individually.

Products With Lower Halal Concern

Some Itsu supermarket products have a simpler, cleaner ingredient profile:

• Itsu Crispy Seaweed Thins — ingredients: seaweed, sunflower oil, rice flour, seasoning. These are widely considered permissible. Check the specific flavour for seasoning ingredients.
• Itsu Miso Soup sachets — typically miso paste (fermented soybean), tofu, and wakame seaweed. Standard miso soup does not contain mirin. These are generally considered permissible.
• Itsu Edamame — plain edamame in salted water. No concern.
• Itsu Crispy Noodles — check the flavouring sachet for mirin-based sauces.

Products With Higher Halal Concern

• Itsu Sushi packs — the sushi rice is typically seasoned with rice vinegar, sugar, and salt (permissible). However, sauces accompanying sushi (teriyaki glaze, ponzu, eel sauce) often contain mirin. If the pack includes a separate sauce sachet, check it.
• Itsu Gyoza — the gyoza filling may contain pork or chicken. Pork gyoza are clearly haram. Chicken gyoza without halal certification are Mushbooh (chicken not from halal-certified source).
• Itsu Ramen and noodle soup pots — these frequently contain mirin or sake in the broth paste. Check the ingredients carefully.
• Itsu Katsu Curry — chicken or vegetable. Chicken katsu without halal certification is Mushbooh. The katsu sauce itself may contain mirin.
• Itsu Rice Bowls — depend on the protein and sauce included. Avoid chicken and prawn varieties unless confirmed as halal-sourced.

Gyoza: The Meat Question

Itsu sells both pork gyoza and chicken gyoza in supermarkets. Pork gyoza are clearly off the table. For chicken gyoza, the concern is that Itsu does not source from halal-certified suppliers and holds no halal certification — making chicken gyoza Mushbooh.

Itsu also sells vegetable and edamame gyoza which avoid the meat concern, though mirin in the accompanying sauce still applies.

Itsu Restaurants: Variable

The Itsu restaurant chain operates across London and other UK cities. The restaurants are not halal-certified. Some individual Itsu restaurant locations have been reported to source halal chicken for their chicken dishes, but this is not uniform across the estate, and there is no certified, audited halal supply chain. Cross-contamination with pork products (pork gyoza, certain rolls) in a kitchen without halal controls is a risk.

Do not assume restaurant Itsu chicken is halal without confirming with the specific site.

What Muslims Should Look For on Itsu Labels

1. Mirin — if listed in ingredients, the product contains trace alcohol from rice wine
2. Cooking wine / rice wine — same concern as mirin
3. Pork or lard — immediately disqualifying; present in pork gyoza and some products
4. Chicken — if not halal-certified, treat as Mushbooh
5. Sauces and sachets — check these separately; the base product may be clean but the sauce may contain mirin
6. “Natural flavouring” — in Japanese food products may include dashi (fish-based), usually permissible, but follow up if uncertain

Summary

Factor	Details
Halal certification	None — supermarket or restaurant
Meat concern	Pork in some products (haram); chicken not certified (Mushbooh)
Alcohol concern	Mirin and cooking wine in multiple products
Safest choices	Seaweed snacks, plain miso soup, edamame, veg sushi without sauces
Restaurant	Not certified — individual site sourcing varies
Recommendation	Choose products with fully plant-based / seafood ingredients; always check for mirin in sauces; avoid chicken and pork products without halal certification

Itsu is not a halal-hostile brand — much of its range is plant-forward — but the consistent use of mirin in Japanese-style cooking means that Muslims who avoid all forms of cooking alcohol should check every label carefully before consuming.
