What Is Wasanbon? — Traditional Premium Japanese Sugar
Wasanbon is a traditional Japanese premium sugar and a specialty product with a long history in parts of Kagawa and Tokushima prefectures.
It is mainly used in high-end wagashi (Japanese sweets) and is known for its elegant sweetness and melt-in-your-mouth texture.
While white sugar and brown sugar are more common, Wasanbon is made using a unique traditional method, giving it a deeper sweetness and making it an excellent match for Japanese tea.
One theory says the name “Wasanbon” comes from its refining process.

Wasanbon Features — The Secret Behind Its Elegant Sweetness and Smooth Melt
1. Elegant Sweetness and Distinctive Flavor
Wasanbon is not as intensely sweet as white sugar, offering a mellow and gentle sweetness.
It has a clean finish with a subtle richness.
The molasses that remains in moderation creates a natural flavor containing minerals.
2. A Texture That Melts in Your Mouth
Wasanbon has very fine particles that dissolve quickly in the mouth.
This smooth mouthfeel is a unique charm you don’t get from other sugars!
The fineness of the particles is said to be related to the hand-worked “togi” polishing process.
3. A Handcrafted Specialty Made with Traditional Methods
Wasanbon is made using traditional production methods.
Because of this, mass production is difficult, and it remains a premium sugar crafted by artisans by hand.
It is also known for requiring significant time and labor.

How Wasanbon Is Made — Traditional Sugar-Making Process Starting with Chikutō Cane
1. Made from Chikutō Sugarcane
Wasanbon is made from chikutō (a traditional sugarcane variety with a slender, bamboo-like appearance).
Compared with common sugarcane, its stalks are thinner and yields are lower, but it is said to contain less fiber.
Chikutō is cultivated in parts of Kagawa and Tokushima.
2. Traditional Sugar-Making Steps (Togi, Oshi Pressing, Drying)
Wasanbon production includes processes called “togi” and “oshibune.”
- Togi: Crude sugar (shirōshita-tō) is boiled down and hardened, then crushed; a small amount of water is added and it is kneaded by hand on a work surface in a polishing step called “togi.”
- Oshi (Pressing): The polished sugar is wrapped in cloth bags, arranged in a wooden box called an “oshibune,” and slowly pressed with weights to squeeze out the molasses.
- Drying: After enough molasses has been removed in the oshibune, the sugar is loosened, dried, and sifted to make uniform grains, completing “Wasanbon sugar”!
By repeating the togi and pressing steps multiple times, the sugar develops its smooth melt-in-the-mouth texture.
Because these are all handcrafted steps, Wasanbon becomes a sugar with a uniquely delicate mouthfeel.
