Japanese Shumai (焼売) are tender, juicy steamed dumplings filled with seasoned ground pork, onions, and aromatic seasonings, all wrapped in thin shumai wrappers. Popular in Japanese homes, bento boxes, dim sum restaurants, and convenience stores, Shumai are loved for their soft texture, savory flavor, and elegant appearance. Unlike gyoza, shumai are left open at the top, allowing the flavorful filling to remain moist while steaming.
Whether served as an appetizer, lunch, or part of a Japanese feast, homemade Shumai are surprisingly easy to make and incredibly delicious.
What is Shumai?
Shumai is a Japanese adaptation of the Chinese siu mai, featuring a juicy filling of ground pork, finely chopped onions, ginger, and seasonings wrapped in a thin wheat wrapper. The dumplings are shaped into small cylinders with an open top and steamed until tender.
Japanese Shumai is commonly enjoyed with soy sauce, Japanese mustard (karashi), or ponzu sauce.

Preparation Time
- Prep Time: 30 minutes
- Cook Time: 15 minutes
- Total Time: 45 minutes
Servings: 24–30 shumai
Step 1: Prepare the Onion
Place the finely diced onion in a bowl.
Sprinkle with cornstarch and toss until evenly coated.
This helps bind the filling while keeping it juicy.
Step 2: Make the Filling
In a large bowl, combine:
- Ground pork
- Coated onions
- Garlic
- Ginger
- Soy sauce
- Sesame oil
- Sake
- Sugar
- Salt
- White pepper
Mix thoroughly until the filling becomes sticky and well combined.
Step 3: Wrap the Shumai
Hold a shumai wrapper in your hand.
Place about 1 tablespoon of filling in the center.
Gently press the wrapper upward around the filling while shaping it into a small cylinder with an open top.
Flatten the bottom slightly so the shumai stands upright.
Top with a green pea, carrot cube, or corn kernel if desired.
Step 4: Prepare the Steamer
Line the steamer with parchment paper or cabbage leaves to prevent sticking.
Arrange the shumai in a single layer, leaving a little space between each dumpling.
Step 5: Steam
Bring water to a gentle boil.
Steam the shumai over medium-high heat for 10–12 minutes, or until the pork is fully cooked and the wrappers become translucent and tender.
Step 6: Serve
Transfer the hot shumai to a serving plate.
Serve immediately with soy sauce, karashi mustard, or ponzu sauce.
Garnish
Top with:

Tips for Perfect Shumai
- Coat the onions with cornstarch to keep the filling moist.

Delicious Variations

Crab Shumai
Mix imitation crab or fresh crab meat into the filling for extra umami.

Fill with tofu, mushrooms, cabbage, carrots, and edamame for a meat-free alternative.
Storage

Frequently Asked Questions
What is the difference between Shumai and Gyoza?
Shumai are open-topped dumplings that are steamed, while gyoza are crescent-shaped dumplings that are typically pan-fried and steamed. Shumai wrappers are also thinner and shaped differently.
Can I use wonton wrappers?
Yes. Square wonton wrappers can be cut into smaller squares if shumai wrappers are unavailable.
How do I know when shumai are cooked?
The filling should reach an internal temperature of 71°C (160°F) for pork, and the wrappers should be tender and slightly translucent.
Can I make shumai ahead of time?
Yes. Assemble the dumplings a day in advance and refrigerate them, or freeze them for longer storage.
What dipping sauce goes best with Shumai?
Soy sauce with Japanese mustard (karashi) is the classic choice. Ponzu sauce, chili oil, or a mixture of soy sauce and rice vinegar are also excellent options.
Final Thoughts
Japanese Shumai are a comforting and versatile dumpling that combines tender wrappers with a juicy, flavorful filling. Their open-top design, delicate texture, and savory taste make them a favorite for family meals, bento lunches, and festive gatherings.
