What is Kohakutou

Kohakutou, a traditional Japanese candy, consists of a mixture of sugar, water, flavoring, coloring, and agar-agar, a powdered substance derived from red algae. The name “Kohakutou” translates to “amber candy” in Japanese, describing the candy’s translucent, amber-like appearance.

Agar-agar serves as the essential ingredient responsible for giving Kohakutou its distinctive texture. When you mix agar-agar with liquid and apply heat, it thickens and takes on a jelly-like consistency, allowing the creation of these delightful jellies. The Telephone brand of agar-agar is the preferred choice for making Kohakutou, as it yields a clear, crystalline candy that sets beautifully.

Kohakutou comes in various flavors and colors, including green tea, strawberry, grape, and lemon. People often shape the candy into small, irregular crystals resembling gemstones. The candy develops a crunchy outer crust after a few days but remains delightfully chewy inside.

Kohakutou serves as a popular gift and souvenir in Japan, and people frequently enjoy it as a sweet treat during special occasions like weddings and tea ceremonies. The candy is also gaining popularity in other parts of the world due to its unique texture and flavors.

The Importance of Agar in Kohakutou

Kohakutou, a mesmerizing jewel-like candy from Japan, captures the hearts of many with its contrasting texture and delectable taste. One of the primary ingredients responsible for this candy’s unique characteristics is agar, also known as “kanten” in Japanese. But what exactly is agar, and why is it so vital to Koha-kutou?

Key Roles of Agar in Kohakutou

  1. Texture Creation: The unique dual texture of Koha-kutou, with its crunchy exterior and soft jelly-like interior, is achieved because of agar. As the candy dries, the outside becomes crystallized while the inside remains gel-like, a characteristic property of agar gels.
  2. Natural Origin: Being a seaweed derivative, agar is an entirely natural ingredient. Its inclusion ensures that Koha-kutou remains a candy rooted in nature, aligning with traditional Japanese culinary values.
  3. Vegan and Vegetarian Friendly: With the global shift towards more conscious eating, the use of agar makes Kohakutou suitable for vegetarians and vegans, expanding its appeal to a broader audience.
  4. Stability and Durability: Agar provides Koha-kutou with a stable structure. It doesn’t melt easily at room temperature, ensuring the candy retains its form and texture for an extended period.

Agar vs. Other Gelling Agents

While there are other gelling agents like gelatin available, agar stands out for several reasons:

  • Temperature Resistance: Agar gels can withstand higher temperatures compared to gelatin before they start to melt.
  • Transparency: Agar provides a clearer and more transparent finish, ideal for the gem-like appearance of Koha-kutou.
  • Plant-Based Origin: As mentioned, agar’s seaweed origin makes it a preferred choice for those avoiding animal products.

In the intricate dance of ingredients that make Kohakutou so special, agar undoubtedly takes center stage. Its properties, both functional and ethical, make it indispensable in crafting this traditional Japanese candy. When you next savor a piece of Koha-kutou, take a moment to appreciate the role of agar in bringing this delightful treat to life.

Ingredients of Kohakutou

Kohakutou, a famous Japanese candy known for its crystal-like appearance and chewy texture, is made from a few simple ingredients that come together to create a unique and delightful treat. Here are the primary ingredients of kohakutou:

Agar Agar

This natural thickening agent is responsible for imparting koha-kutou with its signature chewy texture. It is also responsible for the candy’s crystal-like appearance.


Sugar is a key ingredient in kohakutou, as it provides sweetness and helps to bind the candy together. Most recipes call for granulated sugar, but some variations may use other types of sugar, such as brown or powdered sugar.


Water is used to dissolve the sugar and agar agar and create the base for the candy. It is important to use the correct amount of water to ensure that the candy sets properly and has the right consistency.


Kohakutou can be flavored with a variety of ingredients, depending on personal preference. Some popular flavorings include fruit juice, tea, and extracts such as vanilla or peppermint. It is important to use high-quality flavorings to ensure that the candy has a delicious taste.

Food Coloring

Food coloring is used to give kohakutou its vibrant colors. While it is not necessary to use food coloring, it can help to make the candy more visually appealing. It is important to use food coloring that is safe for consumption and does not alter the taste of the candy.
