The places on this page sit in a handful of neighbourhoods, some of them far apart: by our estimate Dotonbori and Osaka Station are about an hour apart on foot. So plan one area at a time and take the Metro or the train between them. Six of the fourteen places say, in their own words, that everything they make is gluten-free; the other eight serve gluten-free food, and each card says what to ask. The biggest group is in Namba: Spys Oasis, Gluten-Free&Vegan OKONOMIYAKI Vim, Naki Vegan Sweets and Genji-soba are each about 5 minutes on foot from Dotonbori, and Café NoHo in Kitahorie about 10. Further south, Shinsekai Paprika Shokudo is about 5 minutes on foot from Tsutenkaku, and Vege DELI is about 5 minutes on foot from Sumiyoshi Taisha. In the north, Etincelle Crepe and Anosaki Konosaki in Nakazaki are about 5 minutes apart on foot, about 20 and 15 minutes from Osaka Station, and FOLK cafe + bakery in Fukushima is about 5 minutes on foot from the Nakanoshima Museum of Art. Comeconoco is about 20 minutes on foot from Osaka Castle, and Cafe Mahana in Zaimokucho about 25. Buddha in Higashinari, about 25 minutes on foot from the castle, and My Bakery in Noe (Joto Ward) are further out, each a trip of its own.
A day that works, in Namba: lunch at Spys Oasis, a curry restaurant whose own site says everything, from the ingredients to the drinks and seasonings, is gluten-free; it gives lunch from 11:30 to 15:00, closed on Thursdays, and posts its trading days each month. Dotonbori is about 5 minutes on foot, and Kuromon Market about 10: see the market, but its eat-in corner serves sushi, seafood bowls and tempura bowls, so treat it as a sight, not a meal. For the afternoon, Naki Vegan Sweets, an entirely gluten-free sweets shop about 5 minutes on foot from Dotonbori, gives 13:00 to 21:00, closed on Wednesdays, but its newest news item is from 2024, so check first. End the day with okonomiyaki at Vim, where every dish and drink is gluten-free in its own words; ask whether the okonomiyaki sauce and the soy sauce are gluten-free (tamari). On a day in the north, start at the main tower of Osaka Castle, open from 9:00 (last entry 17:30). Comeconoco, an entirely gluten-free sweets shop and café that bakes with Japanese rice flour, is about 20 minutes on foot, open Wednesday to Saturday, 11:00 to 17:00. Go on to Umeda for lunch at Etincelle Crepe in Nakazaki, entirely gluten-free savoury crêpes on a rice-flour batter made without wheat, open Tuesday to Sunday, 11:00 to 17:00; ask whether any soy sauce in the fillings is gluten-free (tamari). The Umeda Sky Building is about 25 minutes on foot from there, and its observatory stays open until 22:30 (last admission 22:00), so it can wait for the evening.
Japan labels wheat, not gluten: wheat (小麦) must be declared on packaged food, but barley (大麦), rye (ライ麦) and oats are not on the allergen lists, and restaurants have no duty to label allergens at all. Rice-flour bread (米粉パン) is not automatically wheat-free, and almost all shoyu (醤油) is brewed with wheat. The label rules, the gluten-free marks and the shop chains, with sources: our Japan page.
Osaka’s own dishes are wheat dishes. Okonomiyaki and takoyaki are made from a wheat batter, and the sauces that go on top (okonomiyaki sauce, Worcestershire-style sauce, soy sauce) usually contain wheat; even where a shop makes a gluten-free batter, ask whether it is cooked on a griddle (teppan, 鉄板) shared with wheat batter. Kushikatsu is breaded and deep-fried, so the takoyaki of Dotonbori and the kushikatsu restaurants of Janjan Yokocho in Shinsekai are not a meal for you. Soy sauce (醤油) goes into tare, tsuyu and marinades: ask for tamari (たまり), and check that label too, because not all tamari is wheat-free. Spys Oasis is the exception here, since its own words put the seasonings inside its gluten-free claim. Shinsekai Paprika Shokudo marks its takoyaki and kushikatsu vegan and gluten-free on its menu, but not everything carries the mark (the vegan ramen has none), and its draft beer contains barley. At Genji-soba, near Hozenji, the juwari soba (十割そば) is 100% buckwheat and the dashi soy sauce is made without wheat, but it is a soba and tempura kitchen: ask whether your soba is boiled in its own water, and skip the tempura unless they can tell you the batter and fryer are gluten-free. Café NoHo’s waffles are all gluten-free, but its kitchen isn’t. Check the days before you set out: Buddha opens on weekdays only, 10:30 to 15:30, Comeconoco four days a week, FOLK and Vege DELI post their news on Instagram, and My Bakery’s opening hours aren’t readable on its site.
