If you’re visiting Osaka and planning to try local street food, you’ll probably come across kushikatsu – deep-fried skewers of meat, vegetables, or seafood. But before you dip your skewer into the shared sauce, there’s one important rule you need to know:
No double dipping!
This rule might sound strict, but it’s a big part of Osaka food culture. Let’s explore what it means, why it exists, and how to enjoy kushikatsu like a local.
What Is Kushikatsu?

Kushikatsu (also called kushiage) is a popular dish in Osaka, especially in areas like Shinsekai. It’s made by skewering ingredients like pork, shrimp, lotus root, or cheese, coating them in batter, and deep-frying them until crispy. You dip the skewer in a special sweet and savory sauce before eating.
What’s the “Double Dipping” ?

In many kushikatsu restaurants, especially casual or standing bars (tachinomiya), the sauce is served in a shared container. Everyone at the table – or even at the whole counter – dips their skewers into the same metal container of sauce.
To keep things hygienic, you’re only allowed to dip once per skewer. Even if you didn’t get enough sauce the first time, you can’t dip again after taking a bite
・Why Does This Rule Exist?
It’s all about hygiene and consideration for others. Since the sauce is shared, double dipping would mean putting your saliva-covered skewer back into the communal container. That’s a big no-no in Japanese culture, where cleanliness and manners are very important – especially when sharing food.
理由はズバリ「衛生面」と「他人への配慮」です。日本では、食事中の清潔さやマナーがとても重視されます。共用ソースに唾液がついた串を戻すのは、他のお客さんにとっても迷惑になります
・What If I Want More Sauce?
No problem! Most kushikatsu places will provide fresh cabbage on the side. You can use a piece of cabbage as a spoon to scoop more sauce and pour it onto your skewer. This way, you get more sauce without breaking the rule.
Tips for Enjoying Kushikatsu Like a Local
Don’t rush.
Let the skewer cool down a bit before eating – it’s hot!
One dip only.
Remember: once you bite, no more dipping.
Use cabbage smartly.
It’s not just for eating – use it to scoop extra sauce.
Respect the space.
These shops are usually small. Keep your belongings compact and be mindful of others.
Chat with the staff.
Many are friendly and used to tourists. A smile and a “thank you” (arigatou) go a long way!
Kushikatsu is more than just delicious food – it’s a fun and unique cultural experience. Understanding and respecting the “No Double Dipping” rule helps you enjoy it just like the locals do. So next time you’re in Osaka, grab a skewer, dip once, and enjoy!
