I have watched plenty of visitors freeze at a menu with zero English and zero pictures, quietly panic, and either walk out or just point at random and hope. You do not need to speak Japanese to eat well here, but it helps enormously to understand the handful of patterns menus actually follow, which is a very different problem than needing fluency.
Start by reading the restaurant, not the menu
Before you even sit down, the restaurant itself usually tells you what to expect. Plastic food models in the window, common at family restaurants and many casual spots, let you point at the actual dish through the glass before you ever open a menu. A restaurant specializing in one thing, a ramen shop, a sushi counter, a yakitori grill, dramatically narrows what you need to figure out, since the menu is really just variations on that one dish rather than a wide-open field of options.
The vending machine ticket system
A specific and genuinely useful pattern worth knowing: many casual ramen and set-meal restaurants use a ticket vending machine by the entrance instead of table ordering. You select your dish from buttons, often with a photo, insert cash, and a printed ticket comes out that you hand to staff once seated. It looks intimidating the first time but is actually one of the easiest ordering systems here precisely because there is no conversation required at all.
Words worth actually memorizing
A small vocabulary list goes a long way. Teishoku means a set meal, typically a main dish with rice, soup, and a few small sides, generally the best value option on any menu that offers it. Moriawase means an assorted platter, useful when you want variety without picking individual items. Osusume means recommended, often marking the chef's suggested dishes. Nomihodai means all-you-can-drink for a set time and price, common at izakaya. Tabehodai means the food equivalent, all-you-can-eat. Learning these handful of words does more for reading a menu than most people expect.
Let your phone do the heavy lifting
Google Translate's camera mode, where you point your phone at printed text and see a translated overlay in real time, has genuinely transformed how approachable Japanese menus are for visitors. It is not always perfectly accurate, particularly with stylized handwriting on chalkboard specials, but it reliably gets you close enough to understand roughly what you are looking at, which is usually all you actually need.
Reading the numbers even when you cannot read the words
Prices are written in numerals you already know how to read, so even a completely untranslatable menu still tells you what things cost. This alone helps you gauge portion size and formality, a 3,000 yen dish is a different scale of meal than a 500 yen one, giving you a useful signal even before you know exactly what the dish is.
What to do when you are genuinely stuck
Pointing at what another table is eating and asking kore, meaning "this," is a completely normal and accepted way to order in a casual restaurant, staff are used to it and will not think less of you for it. Asking osusume wa nan desu ka, "what do you recommend," is another reliable fallback that puts a good dish in front of you without needing to parse the full menu yourself.
A note on allergies and dietary restrictions
This is the one area where I would not rely on pointing and hoping. If you have a genuine allergy, it is worth having a written note in Japanese, easily generated through a translation app in advance, stating the specific ingredient clearly, since a soy sauce base, dashi stock made from fish, or hidden shellfish can appear in dishes that look entirely unrelated to someone unfamiliar with Japanese cooking. Vegetarian and vegan visitors specifically should know that dashi, a fish-based stock, underlies an enormous amount of Japanese cooking even in dishes that otherwise look plant-based, so a specific, written clarification matters more here than in most countries.
Why this gets easier fast
The first unreadable menu is always the hardest one. After a few meals you start recognizing the same handful of characters for rice, noodle, chicken, and pork showing up again and again, the vending machine ticket system stops feeling strange, and pointing at a photo or another table's dish starts feeling completely normal rather than embarrassing. Eating well in Japan without reading Japanese is entirely realistic, it just takes trusting the system a little on the first try.
