What is Tenshinhan?

Tenshinhan (天津飯) is a Chinese-inspired dish consists of omelette with crab (real crab meat or imitation crab) served over a bed of steamed rice and smothered in a sweet-savory sauce.

The name Tenshin is the Japanese reading of Tianjin, a city in China. It would seem that the name of the dish has to do with the use of the rice grown in Tianjin by the Japanese restaurants in the Shōwa period. The dish is sometimes called Tenshin-don (天津丼) or Kanitama-don (かに玉丼)—”don (丼)” is short for donburi (rice bowl dish).

You’ll notice that tenshinhan shares similar preparation as egg foo young (芙蓉蛋), a classic Chinese omelette dish filled with vegetables and meat and covered in a rich brown gravy. However, despite its Chinese influence, tenshinhan is uniquely Japanese as it originates in Japan. It has been a popular item on the menu at Chinese restaurants in Japan that serve chuka ryori (中華料理), Japanese-Chinese foods, for a half-century.

Did You Know There Is Another Tenshinhan?

When you google “tenshinhan,” you will immediately see a manga character from Dragon Ball that shows up in the search results. I used to watch the show growing up. According to the author, the manga character, Tenshinhan, is indeed named after this crab omelette dish.

How to Make Tenshinhan

Ingredients You’ll Need

  • Crabmeat: Real or imitation crab; I’m allergic to crab so I have to use imitation crab. Japanese imitation crab sticks shred easily and has a nice red color. See variations below if you don’t eat crab.
  • Eggs
  • Steamed rice
  • Green peas
  • Sweet and sour sauce: Chicken stock, soy sauce, sugar, sake, vinegar, potato starch
  • Oil and sesame oil

Overview: Quick Steps

  1. In a saucepan, combine the ingredients for the sweet and sour sauce.
  2. Mix and bring the sauce mixture to a simmer. Once the sauce has thickened, set it aside.
  3. Prepare egg mixture with crabmeat and season it with salt.
  4. Cook the omelette in a frying pan and serve it over steamed rice.
  5. Pour the sweet and sour sauce over the omelette and garnish it with green peas.

5 Tips to Cook Perfect Soft Omelette

Tip #1: Make one omelette at a time.

Tenshinhan is usually served individually like a donburi (rice bowl) style. Because the omelette is done cooking when the texture is just set and soft, it will be impossible to divide the omelette at this stage.

The omelette made with one large egg covers the heap of steamed rice inverted from the regular Japanese rice bowl perfectly.

Tip #2: Use a smaller frying pan.

The ideal presentation of this dish is to enfold the dome-shaped steamed rice with the omelette completely. You may need to practice at least one time so you can adjust the amount of rice and egg to achieve the perfect look.

I use this 8.5-inch cast iron wok (use JOC10 to get 10% off) and it’s a good size to cook a one-egg mixture.

Tip #3: Don’t be shy about oil.

It’s important to use just enough oil so that when you pour the egg mixture, it floats on top of the oil. If you don’t use enough oil, the egg mixture either sticks to the pan and becomes a normal scramble egg instead of a fluffy egg.

Tip #4: Poke the omelette and allow uncooked egg to cook.

As you cook the omelette, poke the egg mixture with chopsticks or silicone spatula so the cooked egg will get pushed to the side allowing the uncooked mixture to fill the open space in the pan.

The key is how quickly you distribute the uncooked egg mixture to the hot pan surface. This way the entire omelette surface can be done cooking at the same time. The worst-case scenario is one part of the omelette is fully cooked and another part is runny or totally uncooked.

Tip #5: Do not flip the omelette!

Stop cooking the omelette as soon as the egg is just set, and no longer runny.

Why don’t we flip the omelette? For the best looking tenshinhan, the egg on the top side should be bright yellow compared to the bottom side that’s been browned from direct heat on the pan.

Slide the omelette over the bowl-shaped rice. The omelette should cover the steamed rice completely. If the omelette is not pliable enough to cover the rice, you probably overcooked it.

It’s ok if the egg is slightly undercooked. You will pour a piping-hot sauce over the omelette so the egg will be cooked just right—super tender and fluffy!

All About the Sweet and Sour Sauce (Amazu-an)

Chinese-influenced food in Japan (aka chuka ryori) often features amazu-an (甘酢あん) or sometimes called chuka-an (中華あん) or simply An (あん). The sweet and vinegary sauce goes with many chuka ryori dishes!

Amazu-an is typically made with 3 ingredients: soy sauce, sugar, and vinegar. Instead of cornstarch used in Chinese dishes, we use potato starch to achieve a thick, gravy-like consistency. Depending on the recipe, the sauce is diluted with chicken stock/broth, like this recipe.

Variations and Options

I made this tenshinhan recipe very simple so that you can always cook the dish when you are short on time or low on ingredients.

If you want to make it more nutritious and savory, here are other ingredients that are commonly used for variations of tenshinhan.

  • Other proteins: Add cooked chicken, shrimp, and pork to the egg mixture. Don’t put too much of it though. It will break the omelette.
  • Dried shiitake mushrooms (save the soaking liquid (= Shiitake Dashi) and use it as a part of the sauce)
  • Enoki mushrooms
  • Shimeji mushrooms
  • Julienned ginger
  • Thinly sliced negi (long green onion)
  • Julienned carrot
