Frequently Asked Questions

The app is free to use. There are no in-app purchases, paid plans, or subscriptions — the Collection, photo-based identification, the seasonal calendar, and every other feature are all free to use.

Yes. Most features — the Collection, the seasonal calendar, the Reading Room, and the show-to-staff cards — run entirely on your device, so you can use the app even without an internet connection. It works fine while traveling abroad or inside a restaurant.

The only feature that needs an internet connection is photo-based identification (Sushi Image Search).

Only the area inside the white frame on screen is cropped from your photo and sent, via our server, to an AI service (OpenAI) to identify the neta in it. The image is used solely for identification and is never stored on our servers.

Identification results are AI estimates, so their accuracy is not guaranteed. For details, see the Privacy Policy and Terms of Service in the app or on this site.

Yes. Multiple pieces on a plate can be identified in a single shot. Each piece in the photo gets a numbered frame, so you can immediately check each neta's name and description.

Note that results may not always be accurate depending on the place, lighting, or the shape of the neta.

From Food Restrictions in Settings, you can set crustacean, egg, wheat, or milk allergies, as well as halal or vegan. Once set, a CHECK label appears in the sushi list and on neta detail pages for items that may match your restrictions.

Actual ingredients and preparation vary by restaurant, so the label is only a guide. If you have food restrictions, always confirm with the restaurant staff.

From Show to Staff on a neta detail page, you can display the neta name you want to order and “ください。” in large Japanese text. The Japanese reading is shown too, so even if you don't speak Japanese, just showing the card is enough to order.

If you have set food restrictions, Show Food Restrictions to Staff displays your allergy, halal, vegan, or other restriction details in Japanese. You can show it directly to staff or copy it into the notes field of a reservation form.

Japanese, English, Korean, Chinese (Traditional/Simplified), French, German, Italian, Spanish, Portuguese, Thai, Vietnamese, and more — the app supports 27 languages and regions. You can switch anytime from Language Settings in Settings.

The app currently includes 54 kinds of neta. You can see explanations and season notes organized by category — red-fleshed fish such as tuna, silver-skinned fish such as kohada, squid and octopus, shrimp and crab, shellfish, and conger eel and tamago (egg).

More neta are being added over time. We also welcome requests for neta you'd like to see added.

The Calendar tab at the bottom shows, month by month, which neta are in season at that time of year. Use it as a reference when you want to know what's tasty for the season, or when you're not sure what to order at a restaurant.

Keep in mind that even for the same neta, the season can vary greatly depending on where it's caught. Please treat the calendar as a general guide only.

The Reading Room tab offers trivia and short articles about sushi. New content will be added over time.

The app never sends push notifications. You won't even be asked to allow notifications, so you can use it worry-free.

You can reach us through the Contact form inside Settings. We welcome requests for neta not yet included, corrections to translation errors, and your feedback.
