A visit to a sushi restaurant can be a multisensory experience. From the delicate balance of flavors in a single piece of nigiri to the mesmerizing skill of an itamae (sushi chef) at work, there’s a lot to appreciate. But beyond the delicious food and elegant presentation lies a world of tradition, etiquette, and hidden details that even the most seasoned sushi enthusiasts might not know.
Many of the practices inside a sushi restaurant are rooted in centuries of Japanese culinary history. These traditions are not just for show; they are designed to preserve the quality of the ingredients, enhance the dining experience, and show respect for the craft. Understanding these nuances can transform a simple meal into a deeper cultural appreciation.
Are you using your chopsticks correctly? What does the color of the ginger really mean? And what’s the story behind that plastic grass divider in your takeout box? This guide will reveal 12 surprising things about sushi restaurants, offering you a new perspective on your next Japanese meal. Prepare to learn the secrets that will make you a more informed and appreciative diner.
It’s Okay to Use Your Hands
While many diners instinctively reach for chopsticks, it is perfectly acceptable—and often traditional—to eat certain types of sushi with your hands. Specifically, nigiri (a slice of fish over a bed of rice) and maki (sushi rolls) are considered finger foods. The practice dates back to a time when sushi was sold as a quick, casual street food in Japan.
Eating nigiri by hand can actually enhance the experience. It allows you to feel the texture of the rice and fish, and it makes it easier to handle the delicate piece without it falling apart. When eating nigiri, you should pick it up with your thumb, index, and middle fingers. Gently turn it upside down so you can dip the fish side—not the rice—into the soy sauce. This prevents the rice from absorbing too much soy sauce, which can overpower the flavor of the fish and cause the rice to disintegrate.
Of course, using chopsticks is also completely fine. They are essential for eating sashimi (sliced raw fish without rice) and for picking up pieces of ginger. The choice is ultimately yours, but don’t feel self-conscious if you prefer to use your hands for nigiri. It’s a sign that you appreciate the traditional way of enjoying sushi.
There’s a Proper Way to Use Wasabi
That green paste on the side of your plate is a powerful condiment, but many people use it incorrectly. The common practice of mixing wasabi directly into the soy sauce to create a slurry is generally frowned upon by sushi chefs. This method can dilute the distinct flavors of both the wasabi and the soy sauce.
The traditional way to use wasabi is to apply a very small amount directly onto the piece of fish before dipping it in soy sauce. This allows you to control the amount of heat and ensures that the pungent kick of the wasabi complements, rather than overwhelms, the delicate taste of the fish. In high-end omakase restaurants, the chef will often place the perfect amount of wasabi between the fish and the rice for you, so no extra wasabi is needed. This is done because the chef has tailored the amount to perfectly balance the specific cut of fish.
It’s also worth noting that the “wasabi” served in many Western sushi restaurants isn’t always the real thing. True wasabi is made from the grated stem of the Wasabia japonica plant, which is difficult to cultivate and very expensive. More often than not, what you’re getting is a mixture of horseradish, mustard powder, and green food coloring. Real wasabi has a more complex, herbal flavor and a heat that dissipates quickly, unlike the lingering burn of horseradish.
Ginger Is a Palate Cleanser, Not a Topping
The thinly sliced, pickled ginger (gari) that accompanies your sushi at En Sushi has a specific purpose, and it isn’t meant to be eaten in the same bite as your sushi. Ginger serves as a palate cleanser. Its sharp, sweet, and slightly spicy flavor is intended to refresh your mouth between different types of fish.
When you transition from a delicate whitefish like flounder to a richer, oilier fish like tuna or salmon, eating a small piece of ginger helps reset your taste buds. This ensures you can fully appreciate the unique flavor profile of each piece of sushi without the lingering taste of the previous one. Think of it as hitting a refresh button for your palate.
Piling ginger on top of your sushi is considered poor etiquette, as it masks the subtle flavors the chef has worked carefully to create. The only exception might be for certain types of very oily fish, where a touch of ginger can help cut through the richness. However, as a general rule, enjoy the ginger on its own between bites.
Not All Ginger Is Naturally Pink
The pale pink ginger you often see in sushi restaurants might look pretty, but its color is usually not natural. Young, freshly pickled ginger can have a faint pinkish hue, but the vibrant pink color is almost always the result of artificial food coloring (like Red #40) or natural colorants like beet juice.
Originally, the pink tinge came from the chemical reaction between the young ginger and the pickling vinegar. However, as the demand for pickled ginger grew, manufacturers started using older, more mature ginger, which doesn’t turn pink on its own. To maintain the appealing pink color that customers came to expect, producers began adding dyes.
Natural, uncolored gari has a pale yellow or off-white color. While the color doesn’t typically affect the taste, some purists prefer uncolored ginger because it’s free from artificial additives. If you see pale yellow ginger at a sushi restaurant, it can be a sign that the establishment pays closer attention to the quality and authenticity of its ingredients.
Your Chef Isn’t Judging You (Usually)
The image of the stoic, serious sushi chef can be intimidating, but most itamae are focused professionals dedicated to their craft. They are concentrating on preparing your food with precision and care, not silently judging your chopstick skills or your order. In fact, many chefs are happy to see diners enjoying their creations.
However, there are a few behaviors that might raise a chef’s eyebrow. As mentioned, mixing wasabi into soy sauce or topping sushi with ginger are common faux pas. Another is rubbing your chopsticks together. This action implies that you think the chopsticks are cheap and splintery, which can be seen as an insult to the establishment. Good quality chopsticks won’t need this treatment.
If you are sitting at the sushi bar, it’s a great opportunity to interact with the chef. You can ask for recommendations or compliment the food. This shows respect for their skill and can enhance your dining experience. Just be mindful of their workflow; if the restaurant is busy, keep the conversation brief.
Tuna Terminology is Complex
Tuna is a cornerstone of any sushi menu, but not all tuna is the same. The terminology can be confusing, as different parts of the fish have different names, flavors, textures, and price points. Understanding these terms can help you order like a pro.
- Akami: This is the lean, bright red meat from the sides of the tuna. It has a firm texture and a clean, meaty flavor. It’s the most common and affordable cut of tuna.
- Chutoro: This is the medium-fatty part of the tuna, usually found along the belly and back. It has a softer, more buttery texture than akami and a richer flavor. It’s a perfect middle ground between lean and fatty.
- Otoro: This is the prized, fattiest part of the tuna, taken from the underside of the fish’s belly. It’s incredibly rich, with a melt-in-your-mouth texture and a complex, savory flavor. Otoro is the most expensive and sought-after cut of tuna.
Knowing these distinctions will allow you to appreciate the variety that a single fish can offer. Trying a flight of all three—akami, chutoro, and otoro—is a fantastic way to experience the full spectrum of tuna flavors.
That Little Green Plastic Grass Has a Name
That small, spiky piece of green plastic that often separates items in a bento box or takeout sushi container is not just for decoration. It’s called haran or baran, and its original purpose was functional.
Historically, chefs used real bamboo or aspidistra leaves to partition food. These leaves contain natural antibacterial properties that helped slow the spoilage of raw fish and prevent flavors from mingling. The serrated edges of the leaves were also thought to make the food more appealing.
As plastic became more common and affordable, the real leaves were replaced with green plastic replicas. While the plastic haran doesn’t have any antibacterial benefits, it still serves a practical purpose by keeping different food items separate and adding a splash of color. It’s a nod to tradition that has survived in the age of modern food packaging.
The “Sushi Grade” Label Is a Marketing Term
You may have seen fish labeled “sushi grade” or “sashimi grade” at the grocery store and assumed it was an official designation of quality or safety. In reality, these terms have no legal or regulatory definition. They are simply marketing phrases used by fish sellers to indicate that they believe the fish is of high enough quality to be eaten raw.
The U.S. Food and Drug Administration (FDA) does have guidelines for fish intended for raw consumption. It recommends that fish be frozen at very low temperatures (-4°F for 7 days or -31°F for 15 hours) to kill any potential parasites. Most of the fish you eat at a sushi restaurant, with a few exceptions like certain species of tuna, has been previously frozen to meet these safety standards.
When buying fish to make sushi at home, don’t just rely on the “sushi grade” label. It’s more important to buy from a reputable fishmonger who you trust. Ask them if the fish is suitable for raw consumption and how it has been handled and stored.
The Tea Served Is an Important Part of the Meal
The hot green tea often served at sushi restaurants, known as agari, is more than just a complimentary beverage. It plays an important role in the dining experience, similar to ginger. The slightly bitter and astringent qualities of the tea help to cleanse the palate, especially after eating oily fish.
Sipping green tea between different courses can refresh your taste buds, allowing you to better appreciate the flavors of the next dish. It’s particularly effective at cutting through the richness of fatty tuna or eel. Unlike other beverages like soda or alcohol, the simple, clean taste of green tea doesn’t interfere with the delicate flavors of the sushi.
In traditional sushi establishments, the tea is usually refilled throughout the meal without you having to ask. It’s a small but significant part of the hospitality and the overall structure of the meal.
The Rice Is Just as Important as the Fish
While the fish often gets all the attention, sushi is truly a partnership between the fish and the rice. In fact, the word “sushi” actually refers to the vinegared rice (shari), not the fish. A great sushi chef, or itamae, spends years mastering the art of making perfect sushi rice.
The process is meticulous. It involves selecting the right type of short-grain rice, washing it thoroughly, cooking it to the perfect consistency, and then seasoning it with a precise mixture of rice vinegar, sugar, and salt. The rice should be served at or near body temperature, which helps to bring out the flavor of the fish. Each grain should be distinct yet stick together just enough to hold its shape.
A chef’s skill is often judged by the quality of their rice. If the rice is too mushy, too hard, too sweet, or too sour, it can ruin the entire piece of sushi, no matter how high-quality the fish is. Next time you eat sushi, pay close attention to the rice—its temperature, texture, and flavor are all signs of the chef’s expertise.
Omakase Means “I Leave It Up to You”
If you’ve ever seen omakase on a menu, you might have wondered what it means. Omakase is a Japanese phrase that translates to “I’ll leave it up to you.” When you order omakase, you are entrusting the chef to create a custom, multi-course meal for you based on the freshest and best ingredients available that day.
An omakase experience is considered the highest form of sushi dining. It allows the chef to showcase their creativity and skill, presenting a series of dishes that progress in a deliberate order, often from lighter-flavored fish to richer, more intense ones. It’s a culinary journey curated by an expert.
Choosing omakase is a great way to try new things and experience the best a restaurant has to offer. It also shows a great deal of trust and respect for the chef. Be sure to communicate any allergies or strong dislikes beforehand, but otherwise, sit back and let the chef guide you.
Your Soy Sauce Dish Shouldn’t Be Full
It’s a common habit to fill the small soy sauce dish to the brim. However, you only need a small amount of soy sauce for dipping. Overfilling the dish can lead to waste, and in traditional Japanese culture, wasting food (including condiments) is considered disrespectful.
Pour just a small puddle of soy sauce into your dish—enough for a few dips. You can always add more if you need it. As mentioned earlier, the goal is to lightly kiss the fish with soy sauce to enhance its flavor, not to soak it. Using a smaller amount of soy sauce helps you achieve this delicate balance and shows that you are a mindful and considerate diner.

Dining at a sushi restaurant is about more than just eating; it’s about participating in a rich culinary tradition.
