Anpan: Soft Japanese Sweet Red Bean Buns (あんぱん)

How to make anpan, the Japanese sweet bread filled with azuki bean paste, as 8 home-style buns with instant yeast. Covers mixing and kneading to the windowpane stage, judging the first and second rise by volume and a finger dent, wrapping 35 g of paste per bun, egg wash and black sesame, and baking at 200°C. Also explains how this home version differs from Kimuraya's traditional sakadane anpan, and how to choose between tsubuan and koshian.

Cooking steps

STEP 11 / 9

Mix the dry ingredients

Bread flour, cake flour, sugar, salt and instant yeast being mixed in a bowl
Only the dry ingredients go in at this stage

In a mixing bowl, combine the 225 g bread flour, 3½ tbsp cake flour, ¼ cup sugar, 1 tsp kosher salt and 1 tsp instant yeast. The instant yeast goes straight in with the flour; there is no need to dissolve or proof it first.

STEP 22 / 9

Add the egg, milk and water and bring it together

Egg, milk and water being mixed into the flour to form a sticky rough dough
Early on, the dough is rough and sticky, and the butter is not in yet

Beat the dough egg and add it with the 50 ml milk and 50 ml water, both warmed to about 30°C. Mix until there is no dry flour left and the dough comes together into a sticky mass. It will be sticky at first; don't respond by adding a lot of extra flour.

STEP 33 / 9

Knead, add the butter and knead to a windowpane

A small piece of kneaded anpan dough stretched into a thin translucent windowpane
After the butter is kneaded in, check that the dough stretches into a thin film

Knead for about 5 minutes. Then stretch the dough out, wrap the small pieces of unsalted butter inside it and keep kneading. The dough is ready when it holds together smoothly and a small piece can be stretched into a thin, translucent film (the windowpane test). The source's guide for hand kneading is about 15 minutes in total, but go by the state of the dough. You can lightly dust the counter with flour, but avoid adding large amounts.

STEP 44 / 9

First rise until about doubled

The whole batch of dough risen to about double in a bowl, with a finger testing a dent
Check the first rise by the volume and a finger dent

Pull the surface taut as you shape the dough into a ball, put it in a bowl, cover it and leave it in a warm place for about 1–2 hours, until it is roughly doubled in volume. Press a floured finger into the dough: if the dent doesn't spring back right away, move on. The source's author mentions a proofing setting of 38°C on their own appliance; that is one example, not a required dough temperature.

STEP 55 / 9

Divide into 8 and rest for 15 minutes

Eight equal plain dough balls resting on parchment under loosely lifted plastic wrap
Divide evenly and cover so the pieces don't dry out during the rest

Press out the gas and divide the dough into 8 equal pieces. Weighing them on a scale helps keep the finished buns even. Round each piece, cover them and let them rest at room temperature for 15 minutes.

STEP 66 / 9

Shape and wrap 35 g of bean paste in each

35 g of coarse bean paste in the center of an 8 cm round of dough, with the edges being gathered closed
Keep the paste in the middle and the edges clean so the seam closes well

Flatten each rested piece by hand, fold it in thirds twice as the source does, and round it again. Then spread it into a circle about 8 cm across and place 35 g of bean paste in the center. Gather the edges toward the middle, pinch the seam firmly closed and set the bun seam side down. Keep the paste off the edges of the dough; if it gets onto them, the seam is harder to close.

STEP 77 / 9

Second rise for about 30 minutes

Eight sealed anpan, seam side down, pale and risen after the second proof
After the second rise, the buns are puffed and still pale, with no egg wash yet

Cover the buns so they don't dry out and let them rise for about 30 minutes, until roughly doubled. During this time, preheat the oven to 200°C. If you used the oven for proofing, move the buns to another warm spot first so you can preheat.

STEP 88 / 9

Brush with egg wash and add the black sesame

Proofed anpan brushed with a thin egg wash, with black sesame in the center, next to a brush and a bowl of egg wash
A thin coat of egg wash is enough

Whisk the glaze egg with 2 tbsp water and brush a thin layer onto each bun. You don't need to use it all. Place the black sesame in the center of each bun: the source either presses it on with a small round stick dipped in egg wash and then sesame, or simply sprinkles it on.

STEP 99 / 9

Bake at 200°C for 13–15 minutes and cool on a rack

Baked golden anpan cooling on a wire rack, one cut open to show the bean paste and soft crumb
Cool on a rack; the inside should show soft crumb around the paste

Bake at 200°C for 13–15 minutes. If you see uneven browning across the sheet partway through, turn it around once. For a convection oven, the source advises lowering the temperature by 15°C. These temperatures and times are the source's guide, and home ovens vary, so look for an even golden-brown surface. When they're done, move the buns to a wire rack to cool. Anpan can be eaten warm or at room temperature.

Anpan: Bread Dough Around Sweet Azuki Paste

What this batch should keep

A soft, lightly sweet bread on the outside, a neat center of sweet azuki bean paste on the inside, and a thin glossy golden top with a small dot of black sesame. Judge each stage by how the dough looks and feels, not by the clock alone.

Break a small golden bun in half and a mound of dark, sweet azuki bean paste appears in the middle of soft, pale bread. That is anpan: the name joins an (sweet bean paste) and pan, the Japanese word for bread. It sits somewhere between a Western-style bread and a Japanese confection, and this article bakes a batch of 8 of them.

The recipe here is a home-style dough leavened with ordinary instant yeast, following a single published home recipe from Just One Cookbook. It is not a recreation of the traditional sakadane anpan, whose starter is made from rice, koji and water and takes long, careful management. So expect a soft, sweet yeast bun with bean paste, not the particular aroma of a sakadane bun.

This recipe has not been kitchen-tested by Sekai Gohan

The amounts, temperatures and times below come from the published source recipe. This version has not been test-baked in our kitchen, so ovens, room temperatures and ingredients may give different results. Use the visual checks in each step to decide when to move on.

Where Anpan Comes From

By the account of Kimuraya Sohonten, the bakery itself, anpan began in Tokyo in 1874 (Meiji 7). Kimuraya explains that it took a hint from sakamanju, a steamed bun made with a sake-related starter, and made a bread dough with sakadane, a starter of rice, koji and water, to suit Japanese tastes, then filled it with bean paste. Nippon.com's overview likewise describes anpan as invented in Tokyo in 1874, combining the sweet filling of a manju with bread. These are the company's own history and an editorial summary rather than an independent historical study, and they are presented here that way.

Both Kimuraya and Nippon.com also describe anpan being presented to Emperor Meiji in 1875. Kimuraya's version is the sakura anpan, which uses salt-pickled double-flowered cherry blossoms. The cherry blossom belongs to that story and to Kimuraya's own bun; it is not part of the basic recipe in this article.

Anpan can be thought of along two choices. One is the starter: traditional sakadane, or commercial yeast as in most home recipes. The other is the paste: tsubuan, with the beans left coarse, or koshian, strained smooth. The source recipe uses tsubuan and says koshian works too. This version takes the home route: instant yeast and tsubuan. You can find more dishes from the same country on the Japan page.

Ingredients for 8 Anpan

Ingredients for anpan laid out in groups for the dough, the bean paste, the egg wash and the black sesame
Keep the dough egg and glaze egg, and the dough water and glaze water, apart from the start

The dough amounts follow the source recipe exactly, in its own units. Cake flour, sugar and butter are given by spoon and cup, and the salt and yeast by teaspoon; no gram equivalents are added here, because the source's metric values were not obtained for this version. For measuring in this version, a cup is defined as 240 ml, a tablespoon as 15 ml and a teaspoon as 5 ml. These are rounded editorial measuring conventions, not metric values retrieved from the source, and they do not establish gram equivalents.

There are two eggs in total, but they have separate jobs: one goes into the dough and one into the glaze. The liquids are separate too: milk and water for the dough, and 2 tbsp water for the glaze. The source's ingredient list gives the bean paste as 10 oz, while its method wraps 35 g in each bun. This version portions 280 g (35 g × 8) to match the method; the two figures are close but not exactly the same amount, so don't add the difference into the buns.

Equipment

  • Mixing bowl
  • Digital kitchen scale (helps with weighing the flour, dividing the dough into 8 and portioning the paste)
  • Bench scraper
  • Plastic wrap or a cover to keep the dough from drying out
  • Baking sheet
  • Pastry brush
  • Wire rack
  • Oven
  • A small round stick or dowel, if you want to press on the sesame the way the source does (optional)

Choosing the Paste, Salt and Yeast

Bean paste: Store-bought paste works for this recipe, labeled tsubuan (coarse) or koshian (smooth). Sweetness and firmness differ between products, and the firmness affects how easily the paste wraps. Keep the 35 g portion either way, and check the product label for allergens.

Salt: The source uses Diamond Crystal kosher salt. Other salts differ in crystal size and in how salty a spoonful is, so don't swap in the same volume of a finer table salt. No tested amount for another salt is given here.

Yeast: This is instant yeast that goes straight into the dry ingredients without proofing first. Don't confuse it with active dry yeast, which is handled differently; follow your product's packaging.

Milk: The source uses whole milk. Using lower-fat milk changes the texture.

Everything else, including bread flour, cake flour, sugar, unsalted butter, eggs, milk and yeast, can usually be found at a supermarket or baking supply shop; no specific brand is needed.

Allergens and raw dough

This recipe contains wheat, egg, milk and sesame. For store-bought bean paste and other packaged ingredients, check each product's label. Cross-contact cannot be ruled out. Do not taste the raw dough, which contains raw egg and raw flour.

Method: From Mixing to the Wire Rack

Volume and touch before the clock

The rising times are guides that change with room and dough temperature. Move on when the dough has roughly doubled and a finger dent doesn't spring right back.

Common Problems and How to Fix Them

Problem What to check What to do
The dough is very sticky Whether you are adding a lot of flour Keep kneading instead of adding much flour. Gather the dough with a bench scraper and handle it lightly, with only a light dusting on the counter. The selected recipe does not use oil on the hands or counter
The dough hasn't risen enough, or has gone too far Volume and the finger dent, not just the time Wait until it is about doubled and the dent doesn't spring right back. Rooms and dough temperatures change how fast it goes
Bean paste leaks out The amount of paste and the edges of the dough Don't put in more than 35 g, keep paste off the edges, and pinch the seam firmly before setting it seam side down
Browning is uneven Position on the baking sheet Turn the sheet around once partway through baking

Variations

  • Koshian instead of tsubuan: The source allows it. Smooth paste gives a different mouthfeel from the coarse beans of tsubuan.
  • Without black sesame: Wrapping and baking work the same without it; only the flavor and look change. The rest of the recipe stays as written.
  • Store-bought paste: Suits this recipe well. Expect differences in sweetness and firmness between products.
  • Homemade bean paste: The source recommends making it ahead, as its own separate recipe, on a different day. This article does not cover cooking the beans.
  • Traditional sakadane anpan: This is not a simple swap for the yeast in this recipe. A sakadane starter needs its own specialized formula and fermentation conditions.

Storing and Serving

Freshly baked anpan is soft and warm; once cooled, the bread and paste settle together. Tsubuan gives bites of bean, while koshian is smooth throughout.

The recipe's author suggests letting the buns cool completely, sealing them in an airtight container, and keeping them in a cool place for 2–3 days, or freezing them for up to 1 month. These are the recipe author's guidelines, not an official food-safety standard, and they cannot be guaranteed for every season, especially in hot, humid conditions. Put the actual temperature where you keep them and any signs of spoilage first. The source gives no reheating method, so none is specified here.

Frequently Asked Questions

Can I make anpan without sakadane?

Yes. This version uses instant yeast, which is how most home recipes work. It makes a soft sweet bun with bean paste, but it does not reproduce the aroma of traditional sakadane anpan, whose starter is made from rice, koji and water.

Can I use something other than tsubuan?

Koshian works too, according to the source. The difference is texture: coarse beans versus a smooth paste.

How much bean paste goes in each bun?

35 g each, for 8 buns. Putting in more makes the buns harder to seal and more likely to leak.

How long do the rises take?

The guides are about 1–2 hours for the first rise and about 30 minutes for the second, with a 15-minute rest after dividing. They are only guides. Decide by volume (about doubled) and by the finger dent.

Can I leave out the black sesame?

Yes; wrapping and baking work the same without it. When you do use it, the source either presses it on with a small round stick dipped in egg wash and sesame or simply sprinkles it on.
