What is Tekkadon?

Tekka-don (鉄火丼) is a delicious bowl of sushi rice (vinegared rice) topped with slices of tuna sashimi, grated wasabi and other tasty toppings like shiso leaves, ginger, and grilled seaweed.

You can simply place the tuna on top of rice and drizzle soy sauce over it, but my recipe includes a homemade marinade to make it extra special.

Brief history of tekka don

You might be surprised to learn that the name "Tekka-don," a bowl of tuna over rice, is pretty strange even for us Japanese. When we hear "tekka (鉄火)," we think of iron (鉄) and fire (火), which brings to mind something hot, but of course, sashimi is served chilled.

The name actually dates back to the Edo period (1603-1867) when betting halls were called "tekkaba (鉄火場)." The first Tekka-don was a bowl of rice topped with shiba shrimps (a type of shrimp seen in East Asia, particularly around Tokyo) on vinegared rice, eaten while betting in these halls.

Later, the main ingredient changed to tuna, creating the modern Tekka-don as we know it today. It's fascinating to discover that this now-common Japanese dish has such a unique origin story!

Tekka don VS Maguro don

There are two types of tuna donburi (rice bowl) dishes: tekka-don and maguro-don. Even many Japanese people can't tell the difference because they look so similar. Some even think they're the same dish!

But in fact, if we look closely, there are differences. One of the biggest differences is whether regular white rice or sushi rice (vinegared rice) is used. Check out the summary below to learn more about their unique features.

What kind of tuna to use for tekkadon

When making tekka don with raw tuna, the key is to use fresh, "sashimi-grade" or "sushi-grade" tuna. This type of fish is prepared and stored so it's safe to eat raw at home.

As for which part of the tuna to use, tekka don is typically made with the lean red part. While you can use other parts, akami is the most affordable, so I recommend using it for tekka don.

Parts of tuna used for sushi and sashimi
The parts near the head are the most expensive, the quality (and price) decreases as it gets closer to the tail.

The lean and meaty red part of the tuna is called "akami" (赤身). It's a popular cut due to its abundance and affordability compared to other parts.

The more decadent and fatty parts are referred to as "toro," with a melt-in-the-mouth texture. "Chutoro" (中トロ) represents the medium-fatty part, while "o-toro" (大トロ) is the extra-fatty part found in the front of the belly. These parts have a pinker hue, are considered premium, and come with a higher price tag.

Ingredients to make Tekka don

  • Vinegared "sushi" rice - It is different from regular white rice. If you want to know how to make sushi rice at home, check out my "How to Make Perfect Sushi Rice (in a pot or rice cooker)" article. I'll also include instructions in the recipe for a small batch.
  • Sashimi-grade tuna - Be sure to use "sashimi grade" products as they are going to be consumed raw. The red lean part (akami) is recommended for tekka-don.
  • Wasabi paste - I recommend S&B's wasabi paste, which is easy to get online. Also, if you want to make your own wasabi, check out my "Wasabi 101" article.
  • Dark soy sauce - Use dark soy sauce. Kikkoman soy sauce is recommended as a soy sauce that is easily available worldwide.
  • Sake - If you want to know more about the importance of sake and how to choose it, check out my "20 Most Useful Condiments and Seasonings for Japanese Cooking" article.
  • Mirin - The use of mirin (sweet cooking rice wine) gives the marinade sweetness and flavor. For mirin that is easily available in the world, I recommend Kikkoman's mirin.
  • Sushi ginger "gari" (optional) - It is used to achieve a more sushi-like flavor and for decorative purposes. It can be omitted if it is not readily available in your area.
  • Olive oil (optional) - It is not a traditionally used condiment, but in my recipe I drizzle a little at the end as a secret touch. It goes surprisingly well with tekkadon!
  • Shiso leaves (optional) - Also called "Ooba leaves". Not only does it add a beautiful green color to the bowl, but the unique taste of shiso leaves are a perfect match for the marinated tuna! The toppings are optional, so feel free to omit or substitute according to your preference.
  • Finely chopped green onions (optional) - This also add a beautiful green color to the bowl. If you have extra scallions in your refrigerator, please try using them.

Instructions on how to make this tekkadon recipe

Tekkadon is made up of two main elements, the sushi rice and the tuna sashimi. In this section, I will teach you step by step how to make a small batch of sushi rice, marinate the tuna and assemble the dish in the most beautiful way. Let's get started!

How to make a small batch of sushi rice

STEP
Wash the rice

Start by measuring the rice and placing it in a sieve over a mixing bowl. Fill with water, swish and drain. Repeat this 3 times in total to wash the rice.

Washing Japanese white rice
STEP
Soak

Transfer the rice to your cooking pot (or rice cooker) with a small piece of kombu and add an equal amount of cold water (1 cup of cold water for each cup of rice). The kombu will add depth of flavour to the sushi rice. Soak them together with a lid on for 30 minutes (1 hour if the environment is cold).

STEP
Add sake

This step is optional, but adding a small amount of sake to the cooking water will improve the flavour and give the rice a shiny quality. I usually add the sake right before cooking.

STEP
Cook

Once the rice and kombu has finished soaking, place the pot on the stove and bring it to a boil over a medium heat. Make sure to stay close to the stove and listen for when it starts to boil (do not remove the lid).

Pot of rice on the stove with the lid on

Cook the rice on the following heat settings and set a timer accordiningly:

  • Boiling on medium - 30 seconds
  • Simmering on medium-low - 2 minutes
  • Simmering on low - 5 minutes
  • Highest heat - 10 seconds
  • Turn off the heat and leave the pot on the stove with the lid on - 10 minutes

The final 10 minutes allows the rice to continue cooking in the steam, so it's important not to remove the lid or interfere with the rice.

How to marinate the tuna

STEP
Burn off the alcohol in the sake and mirin

Pour the mirin and sake into a small saucepan and boil for 1 minute.

Heating sake and mirin in a pan
STEP
Add the soy sauce

Turn off the heat and add the soy sauce to the pan.

Completing the marinade for tekkadon
STEP
Transfer to a wide container

Pour the sauce into a wide container big enough to lay out the tuna in one layer. Allow the sauce to cool down, it should be cool enough to touch before adding the tuna. (You can speed up the cooling process by placing the container in an ice bath.)

STEP
Marinate the tuna

Place a small piece of kombu in the sauce and then dip each piece of tuna in the marinade so that both sides are coated. Lay out the tuna slices in the container so that every piece is in contact with the marinade.

Marinate in the refrigerator for 30 minutes.

Assembling

STEP
Mix the rice

Once the rice has finished steaming, remove the kombu and mix it gently.

Pour the sushi vinegar into the warm rice and mix until well distributed.

Assembling

  1. Once the rice has cooked, remove the kombu and break it up using a rice paddle.
  2. Add the rice vinegar mixture to the rice and mix until evenly distributed.
  3. Divide it into serving bowls and then arrange the slices of marinated tuna on top.
