At a Japanese restaurant, the keto order is sashimi over sushi, plain or salt-grilled skewers over glazed ones, and soy sauce instead of anything sweet. Miso soup and a small side of edamame are fine to start. Skip the rice, the tempura, and anything named teriyaki or eel sauce — those three words are doing the same job "sweet-and-sour" does on a Chinese menu, telling you the carbs before you've even asked. Japanese food is a good cuisine for keto in one specific way and a bad one in another: the protein itself (raw or grilled fish, chicken, beef) is essentially carb-free, but the classic delivery method — a ball of vinegared rice — is built into the name of the dish.
Sushi and sashimi use the exact same fish; the difference is entirely the rice. A single piece of nigiri carries a small, tightly packed ball of sushi rice underneath the fish, and a six-to-eight piece roll can add up to a full serving of rice by the time you've eaten the whole thing — on top of whatever's rolled inside it. Sashimi is the same raw fish with that layer removed, which makes it the simplest swap on this entire menu: you're not asking the kitchen to change anything, you're ordering a dish that already exists exactly as a lower-carb version of the one next to it on the menu.
Yakitori works on a similar principle to grilled meat anywhere else — chicken, beef, or pork on a skewer is just protein and fat until something is brushed on top of it. Ordered shio (salt) or plain, it's carb-free the same way a plain grilled chicken thigh is. Ordered tare, it's been basted in a soy-mirin-sugar glaze that's reduced down to a sticky sauce — good, but no longer carb-free, since mirin is a sweetened rice wine used specifically for that glaze. Asking for shio instead of tare, or asking whether a skewer is already glazed before it's ordered, is a one-word swap that changes the dish without changing what you're eating.
A handful of specific spots where a Japanese menu shifts from easy to a real carb source:
None of this requires giving up the sushi-night ritual. It's one swap at the counter (sashimi instead of a roll), one word to the server (shio instead of tare), and letting the tempura basket and the sweet sauces pass by — the rest of a Japanese menu, fish and all, is genuinely easy to eat through on keto.
Japanese is one of 25 built-in eating-out situations in the app — cuisines, fast food chains, and social situations like family dinners and potlucks — so the sashimi-not-rolls order is already worked out before the menu even arrives.
