Wait, Is That Rude in Japan? Restaurant Rules Even Repeat Visitors Get Wrong

Wait, That’s a Faux Pas? Japan’s Unwritten Restaurant Rules Even Repeat Visitors Miss

Japan Restaurant Rule #1: “I Didn’t Order This!” So Why Did a Small Dish Just Appear?

“I’d barely ordered my drink when a small dish suddenly appeared. I was worried it had been brought to the wrong table, so I didn’t touch it… then I found out I’d been charged for it!” (Woman, 20s)

This is a classic first-time izakaya surprise. At many Japanese izakaya and bars, you may be served a small appetizer called an otoshi even though you never ordered it.

For many international visitors, being charged for something you didn’t ask for can understandably feel a little strange. But in Japan, otoshi is part of the dining culture and is generally treated a bit like a seating or service charge, with a small dish included.

The idea is that you can sip your drink and snack on something while waiting for the rest of your food to arrive. So if a mysterious little plate suddenly lands on your table, don’t panic: it probably isn’t someone else’s order.

Japan Restaurant Rule #2: It’s Freezing Outside… So Why Did I Just Get a Glass Full of Ice?

“I visited Japan during a winter cold snap, and after freezing outside, I finally got into a restaurant… only to be served ice water packed with ice cubes!” (Woman, 40s)

For Taiwanese travelers who are used to drinking warm or hot water, Japan’s year-round habit of serving cold water can come as a bit of a shock. In winter especially, when you’ve just escaped the biting cold outside, a steaming cup of something warm can sound much more appealing.

There’s actually some history behind all that ice. Before refrigerators and modern ice-making became common, ice was a luxury in Japan, so serving chilled water could be seen as a form of hospitality.

If cold water really isn’t your thing, try asking for oyu, or hot water. Just keep in mind that drinking plain hot water isn’t especially common in Japan, so some restaurants may not normally offer it.

Japan Restaurant Rule #3: “Japanese Customers Only?” When a Restaurant Doesn’t Feel Very Welcoming

“Once they realized we weren’t locals, they wouldn’t really help us order. They didn’t want to spend time translating or explaining the food, and after going a few times, I still didn’t feel especially welcome as a Taiwanese customer.” (Woman, 40s)

An experience like this can be frustrating, especially when you’ve been looking forward to trying a particular restaurant.

At some tiny, independently run restaurants in Japan, especially older izakaya or neighborhood spots with only a few staff, the issue may simply be a lack of foreign-language ability or the time needed to explain menus in detail. In those cases, staff can sometimes come across as abrupt or may even turn customers away because they’re worried about communication problems.

That said, you’re on vacation, and you don’t have to force yourself to stay somewhere that makes you uncomfortable. If a restaurant feels unwelcoming, there are plenty of other places that are happy to serve international visitors, so it’s perfectly fine to move on and enjoy your meal somewhere else.

Japan Restaurant Rule #4: Does Your Phone Really Need to Eat First? When Food Photos Go Too Far

“At a conveyor-belt sushi restaurant, we kept ordering without eating because we wanted to fill the whole table with sushi for one big photo. Then I noticed a staff member rolling their eyes at us…” (Woman, 50s)

For plenty of travelers, the phone eats first. And in Japan, there are no shortage of photogenic cafés, dessert shops, and restaurants where snapping a few pictures is completely normal.

But things can be a little different at places where the food is meant to be eaten immediately, such as sushi and ramen shops. From a chef’s perspective, letting sushi sit until the nori turns soft or leaving ramen until the soup cools and the noodles go soggy can feel like watching all that careful preparation go to waste.

There’s also the privacy factor. When taking photos, try not to capture staff or other diners without permission, and avoid turning your table into a full-on photo shoot if it might disturb people around you.

Want the shot? Take one or two quick photos when the food arrives, then dig in while it’s still at its best.

Japan Restaurant Rule #5: Wait, You Can Still Smoke Inside Some Restaurants?

“I went into an izakaya in Japan and was shocked to realize people were smoking inside!” (Man, 40s)

If you’re used to completely smoke-free indoor dining, walking into a Japanese restaurant and suddenly catching a whiff of cigarette smoke can be a surprise. It can be especially frustrating if you dislike the smell or are traveling with children.

Japan significantly tightened its indoor smoking rules in 2020, and restaurants are now generally smoke-free indoors. However, certain qualifying older, small-scale restaurants and izakaya are still allowed to have smoking-permitted areas under transitional rules.

Look for signs near the entrance indicating that smoking is permitted or that the restaurant has a smoking area. One particularly important point for families: anyone under 20, including children and babies, is prohibited from entering areas where smoking is allowed.

Traveling with kids or simply want to avoid the smoke? Check for completely non-smoking when booking or take a quick look at the entrance signs before heading inside.

Know the Unwritten Rules, and Dine in Japan Like a Pro

As the saying goes, when in Rome, do as the Romans do. Japan’s restaurant customs can seem surprisingly strict at first, but once you know what to expect, dining out becomes a whole lot easier.

Keep these little tips in mind and you’ll be ready for everything from tiny neighborhood restaurants to lively izakaya, with fewer awkward moments and much more time to focus on the food.
