Oops! Japan #27 — Don’t Sneak Food into Restaurants

（飲食店で“こっそりお菓子”はNG！）Why That Konbini Snack Could Be a Cultural Mistake

English:

You're sitting down at a ramen shop or a sushi counter. You’re a little hungry, but also craving that konbini rice ball or chocolate bar you bought earlier.

Harmless, right?

Wrong. In Japan, bringing outside food into a restaurant is considered rude, even if it’s something small, even if you’re not “really eating” it.

Why this matters:

Japanese restaurants often take pride in their food quality and presentation.

Eating outside food implies you don’t respect the establishment.

Even handing snacks to your kids at the table can be frowned upon.

Some places may not say anything — but you’ll get looks, or silent disapproval.

It’s not about rules — it’s about manners.

What you can do instead:

Eat your snacks before entering.

If you must feed a child, ask staff politely or choose a casual, family-friendly place.

If you’re not eating the restaurant’s food, don’t sit at their tables. Period.

One Redditor said:

“My friend pulled out a sandwich from 7-Eleven inside a ramen shop. We got stared down by the staff and basically got rushed out.”

Japan is subtle — you won’t always get a warning. But respect speaks volumes.

日本語の補足：

日本では、飲食店に他所から買ってきた食べ物を持ち込むのはマナー違反とされています。

コンビニのおにぎりやスナックであってもNG。

子どもに食べさせる場合でも、店員に一言断るのが礼儀。

特に個人経営の飲食店では、無言で嫌がられることも。

「持ち込み禁止」の札がない場合でも、空気で判断されます。 席を借りるなら、その店の料理を注文する — それが基本のルールです。
