Tempura, soba and udon look like dishes made without meat. But the parts worth checking do not appear in their names: mirin in the dipping sauce and broth, what the dashi stock is made from, the oil used for frying tempura and any meat used as a topping.<\/p>\n\n\n\n

This guide explains where alcohol or pork may be used in tempura, soba and udon, what to look for on a Halal Gourmet Japan listing page, and what to ask at the restaurant. At the end, we introduce restaurants whose listing pages show their halal arrangements.<\/p>\n\n\n\n

The dipping sauce and broth can contain mirin<\/h2>\n\n\n\n

The dipping sauce and broth for soba and udon are made by combining kaeshi, a soy sauce base, with dashi. A page introducing Japanese food<\/a> from Japan’s Ministry of Agriculture, Forestry and Fisheries describes kaeshi for soba dipping sauce as soy sauce, sugar and hon-mirin mixed in a ratio of 5:1:1. Tentsuyu, the dipping sauce for tempura, also often contains mirin.<\/p>\n\n\n\n

Hon-mirin is classified as an alcoholic beverage under Japan’s Liquor Tax Act. For the differences between types of mirin, see our guide to what to check before you order Japanese food<\/a>.<\/p>\n\n\n\n

Dashi varies by restaurant<\/h2>\n\n\n\n

The same ministry page describes making dashi for soba dipping sauce by simmering shaved bonito and mackerel flakes. However, what goes into dashi varies by restaurant, and some dishes use stock made from chicken or pork. You cannot tell from the name of a dish, so ask the restaurant if you are unsure.<\/p>\n\n\n\n

You cannot tell the tempura frying oil by looking<\/h2>\n\n\n\n

Tempura is vegetables or seafood coated in batter and deep-fried. It also appears in other dishes, such as tendon (tempura rice bowl), tempura soba and tempura udon. You cannot tell by looking whether the tempura is fried in the same oil as pork dishes such as tonkatsu.<\/p>\n\n\n\n

Some soba and udon come with meat<\/h2>\n\n\n\n

Some dishes, such as niku soba, niku udon and curry udon, come with meat, and the name of the dish does not always tell you what meat is used.<\/p>\n\n\n\n

What to check on a listing page<\/h2>\n\n\n\n

Of the “Conditions” on each listing page, these four are useful when choosing tempura, soba or udon:<\/p>\n\n\n\n
