Mizu yokan, a Japanese jelly dessert, caught my attention during my stay in Japan. Like my familiar fruit jellies back home, this traditional treat offers a unique twist with its star ingredient—the beloved red bean paste that’s quintessentially Japanese.

Mizu yokan recipe
Yokan is a type of wagashi, which refers to traditional Japanese confections often served with tea. The red bean jelly is typically molded into rectangular or square shapes and sliced before serving. What sets this traditional Japanese sweet apart is its distinctive texture. It has a distinct jelly-like consistency and is made from red bean paste, agar-agar (a vegetarian alternative to gelatin), and sugar.

The key distinction of Mizu Yokan is its higher water content, making it one of the most popular treats in the summer.
With the fruit jelly, you can add different fruits you like. You can do the same thing with yokan by adding different flavors and ingredients to it, such as sweet potatoes, chestnuts, or figs.
Since I made the dish for the first time, I would stick to the original yokan jelly recipe with Mizu Yokan. If you don’t like sugar, you can use honey, syrup, or molasses instead. Here’s how to make Mizu Yokan:

Mizu Yokan – Japanese Jelly Dessert
Nutrition
Ingredients
- 100 g red beans or red bean paste
- 3/4 cup water
- 100 g sugar
- Pinch of salt
- 2 g agar-agar powder (kanten)
Instructions
- Rinse the adzuki beans (red beans) under cold water.
- In a large pot, combine the beans and water. Bring to a boil and let it simmer for about 5 minutes.
- Drain the beans, then add fresh water and bring to a boil again. Reduce the heat and simmer until the beans are tender (usually around 1-1.5 hours). You can reduce the time by using an instant pot/crockpot or soaking them in cold water overnight.
- Once the beans are tender, mash them or blend them until smooth.
- Cook over medium heat, stirring constantly, until the mixture thickens to a paste-like consistency.
- In a separate pot, dissolve the agar-agar powder in water (3/4 cup). Bring the agar-agar mixture to a boil and let it simmer.
- Stir in sugar and a pinch of salt for another minute.
- Add the sweet red bean paste to the agar-agar mixture. Heat the combined mixture over medium heat, stirring continuously until it is well mixed and slightly thickened. This should take about 12 minutes.
- Pour the thickened mixture into a square or rectangular mold, smoothing the surface.
- Allow the Mizui Yokan to cool to room temperature, then refrigerate for about 2-3 hours or overnight until it sets completely.
Notes
How to pair
Mizu Yokan is particularly delightful when paired with various drinks and dishes. Here are some excellent pairing suggestions:
- Food Pairings
- Mochi or Daifuku and yokan create a mix of soft jelly and chewy rice textures.
- Japanese castella offers a diverse dessert combination.
- Fresh fruits like strawberries add contrast to the yokan richness.
- Matcha Ice Cream enhances yokan’s sweet, creamy taste.
- Sashimi’s umami contrasts yokan’s sweetness.
- Whipped coconut milk adds a mild tropical note without overpowering the dessert.
- Drinks
- Lightly brewed green tea enhances the yokan flavor and cleanses the palate.
- Matcha balances the sweetness of yokan.
- Plant-based milks pair well with the dessert’s soft texture.
Yokan variations
Besides the Mizu Yokan recipe, you can try other different variations below:
- Mizu Yokan or “water yokan,” has a higher water content. It has a softer and more delicate texture.
- Neri Yokan has a smoother and silkier texture. It often uses a higher proportion of red bean paste.
- Matcha Mizu Yokan has the best of both words, matcha and anko.
- Shiro Yokan is made with white kidney beans instead of adzuki beans.
- Matcha Yokan incorporates matcha (green tea) into the mixture.
- Yokan with Fruit includes pieces of fruit, such as chestnuts or citrus peel, to add different textures and flavors.
- Imo Yokan blends the rich essence of sweet potatoes with the traditional charm of yokan. Instead of anko, add mashed sweet potatoes to the mixture and bring the mixture to a gentle boil. Once set, you’ll have a luscious treat with a vibrant orange hue.
- Kuri Yokan incorporates chestnuts into the jelly. The chestnuts can be whole or chopped and are often sweetened.
- Mushi Yokan is made with wheat flour or kudzu powder instead of agar. It typically contains sweetened chestnuts and is less shelf-stable than Neri or Mizu yokan.
