Japanese Food Suppliers in the UK: Sourcing Guide for Restaurants (2026)

London has the densest Japanese-restaurant scene in Europe, and the UK supply chain behind it is compact: three or four importers with their own distribution centres around London, a handful of fish specialists, a trade-only wholesale site run by the Japan Centre, and a cash-and-carry in Greenwich. Since Brexit, imports of fish and other animal products from Japan come in under the UK’s own border rules, which is why almost every restaurant buys through an importer. This guide covers the suppliers Japanese restaurants in the UK use, the rules behind each delivery, the ingredients in demand, the items that stay hard to source, and the retail options for small kitchens.

Washoku Agent works with Japanese restaurants across 26 countries on chef recruitment and operations. The information below is compiled from the suppliers’ own websites and official sources, checked on 2026-10-13; confirm current pricing, minimum orders and delivery areas directly with each supplier, and check regulations with the authority named.

Import rules you need to know

• Products of animal origin from non-EU countries, which includes Japanese fish, must be pre-notified through IPAFFS to a border control post at least one working day before arrival, and medium and high risk consignments need a health certificate and are checked at the border. (GOV.UK, Importing live animals or animal products from non-EU countries, January 2025)
• Most imported fish needs a validated catch certificate from the exporting country’s authority, and the documents must reach port health 72 hours ahead for sea freight, 4 hours for rail and air, and 2 hours for road. (GOV.UK, Importing or moving fish to the UK, August 2024)
• Any business that supplies alcohol to other businesses for resale must be approved under the Alcohol Wholesaler Registration Scheme, applying at least 45 days before trading; restaurants buying sake must check that their wholesaler is approved by HMRC. (GOV.UK, The Alcohol Wholesaler Registration Scheme, March 2025)
• Under the UK-Japan Comprehensive Economic Partnership Agreement, preferential tariffs are claimed with a statement of origin or the importer’s knowledge; the importer must hold valid evidence that the product qualifies as originating. Tariff rates differ by product line, so check the UK tariff for each item. (GOV.UK, UK-Japan CEPA guidance on importer’s knowledge, December 2020)
• Every food business must register with its local council at least 28 days before trading; registration is free and cannot be refused. (GOV.UK, Starting a food business, August 2026)

Notable Japanese food suppliers and distributors in the UK

The suppliers below were selected because Japanese restaurants use them, and each one’s website was opened on the date shown. For a neutral list of outlets that use Japanese ingredients, JETRO’s Japanese Food Supporter Store programme is searchable by city.

Japanese ingredients in highest demand in the UK

What the importers lead with tells you what sells: sushi rice (most of it grown in Italy and milled for the UK market), fresh and frozen fish for sushi, nori and the sushi-kit range, soy sauce, miso and mirin, noodles, and sake and shochu for the on-trade. A 2020 survey by JJ Food Service of 69 UK sushi and Japanese restaurants found that about 40 percent struggled to find a single supplier for their full basket, which is why most restaurants run two or three accounts.

How to choose a Japanese food supplier in the UK

• Start with one broad-line importer for groceries and frozen (Tazaki, Wismettac Harro or Japan Food Express) and add a fish specialist (Atariya wholesale or True World Foods UK). Ask each for delivery days in your postcode and order cut-off times. (Supplier websites opened in this guide, October 2026)
• For sake, confirm the wholesaler’s AWRS approval and whether the restaurant’s premises licence covers the sales you plan; the importer holds the duty paperwork, the restaurant holds the licence. (GOV.UK, AWRS, March 2025)
• Do not import fish on your own account unless you have a clearance agent: pre-notification, health and catch certificates and border checks are the importer’s job and the reason their prices include it. (GOV.UK, importing animal products and fish, August 2024)
• Use JETRO’s Supporter Store list to see which London restaurants are certified as using Japanese ingredients, then ask their chefs who delivers. (JETRO, Japanese Food and Ingredient Supporter Stores, September 2026)

The bigger picture

The UK supply chain is smaller than the US one but complete: importers with London distribution centres, specialist fish houses, a trade-only wholesale site and a cash-and-carry. The friction since Brexit sits in border paperwork and freight, not in availability. What restaurants in London tell us they lack is the chef who can judge the fish and run the counter, and that is where we start.
