What is Kohakutou?
Kohakutou is a traditional Japanese sweet, named after the beautiful amber-like translucence it exhibits.
Made primarily from sugar and agar, it features a crisp, crystalline exterior and a soft, jelly-like interior.
The delicate texture and sparkling appearance make it a treat for both the eyes and the palate.
Often called “edible jewels,” Kohakutou has been cherished for centuries as a confection that reflects the beauty of nature and the changing seasons.

History of Kohakutou
The origins of Kohakutou date back to the Edo period.
During that time, sugar was a luxury item, so these sweets were often reserved for special occasions and gifts.
Over time, as sugar became more accessible, Kohakutou evolved into a popular treat enjoyed by people of all ages. Today, it is celebrated not only for its taste but also for its aesthetic appeal, with modern variations incorporating vibrant colors and seasonal designs.
Varieties and Flavors
Though the basic recipe is simple—sugar and agar—the possibilities for customization are endless.
- Flavors: Traditional flavors include plum, yuzu (Japanese citrus), and matcha, while modern creations may feature strawberry, lavender, or other herbs.
- Colors: From single-tone clarity to delicate gradients, the colors can be customized to match seasons or personal preferences.
- Shapes: Classic cubes, spheres, or decorative cuts create visual interest, making each piece a miniature work of art.
These variations allow Kohakutou to be both a dessert and a visually stunning decoration for tea ceremonies, parties, or gifts.
How to Make Kohakutou
Making Kohakutou at home is surprisingly simple, though attention to detail can elevate the final result.
- Sugar and Agar Ratio: Balancing these ingredients ensures the perfect crystalline surface and soft interior.
- Drying Time: Allowing the sweets to dry properly develops the characteristic crisp coating.
- Coloring and Flavoring: Natural colors, fruit purees, or matcha powder can be added to create your own unique designs.
The process may require patience, but the result is rewarding—a treat that delights both visually and in taste.
Enjoying Kohakutou with Matcha
Kohakutou’s subtle sweetness pairs perfectly with the slightly bitter and earthy taste of matcha.
