Kurizuki Kumamoto: A Pure Japanese Chestnut Sweet You Shouldn’t Miss

 Kurizuki: A Taste of Kumamoto’s Quiet Elegance

Across Japan, every region has its own distinctive food culture; shaped by local climate, ingredients, and generations of craftsmanship. Even within the world of wagashi, these sweets are far more than simple treats; they are small stories that speak of the land where they were born.

In this article, I would like to introduce Kurizuki, a confection from Kumamoto that I first encountered in 2025. This sweet played a defining role in shaping the direction of my current business.

When I received it as a gift and tasted just one piece, I was stunned by how delicious it was. At the same time, I couldn’t help thinking:

“How can something this good be so little known—even within Japan?

And of course, almost no one overseas knows it.

There isn’t even an English introduction page.More people deserve to know this.”

What Exactly Is Kurizuki?

Kurizuki is a small, round wagashi made from just three ingredients:

Kumamoto-grown Japanese chestnuts, sugar, and starch syrup.

That’s all. Its appearance is extremely simple and I remember being surprised by how unadorned it looked when I first opened the package. But beneath that simplicity lies a depth of flavor that only true craftsmanship can create.

The texture is moist and gently cohesive. The sweetness is restrained, allowing the natural richness of the chestnut to unfold quietly but unmistakably. There is no decoration, no added flavoring—just the pure essence of the ingredient itself. It embodies the Japanese philosophy of subtracting everything unnecessary so that what remains can shine.

This, to me, is the beauty of Japanese confectionery.

What Makes It Special?

I am not an expert in food processing, so I will share an excerpt from the maker’s official explanation. The deliciousness of Kurizuki comes from meticulous sourcing, careful handling, and remarkable speed at the production site:

“Chestnuts harvested in the morning are collected and sorted the same day.

Only those that meet strict standards for size and shape are selected.

They are immediately refrigerated to remove heat, preserving the delicate flavor that chestnuts easily lose.

Refrigeration locks in umami and enhances sweetness. Only chestnuts that pass this rigorous selection are processed into a rich paste at our own facility, and used to create our confections.”

Deep Roots in Kumamoto

Blessed with fertile soil and pristine water, Kumamoto has long been known as one of Japan’s major chestnut-producing regions.

Kurizuki is made by Fukudaya, a confectionery company founded in 1948.

Despite producing its own products, it remains a relatively small company with fewer than 100 employees. What I admire most is how deeply rooted the company is in its community. Fukudaya has contributed to local recovery efforts after major earthquakes in Kumamoto, showing a commitment not only to craftsmanship but also to the people and land that support it.

FYI: What Kind of Place Is Kumamoto?

Kumamoto is located in the heart of Kyushu, the southernmost of Japan’s four main islands.

It is known for:

• Mount Aso, one of the world’s largest active volcanic calderas

• Abundant natural springs and exceptionally clean water

• Rich agricultural land, producing chestnuts, citrus, melons, and more

• Kumamoto Castle, one of Japan’s most iconic historical landmarks

• A warm, welcoming culture shaped by both nature and resilience

The region’s clean water and fertile soil make it an ideal environment for growing high-quality chestnuts; an essential foundation for Kurizuki’s flavor.

Review

I first received Kurizuki as a souvenir from my sister who had visited Kumamoto.

The packaging was simple, and the sweet itself looked modest; so modest that, honestly, I wasn’t expecting much.

But the moment I took a bite, everything changed.

The texture was moist and tender, and the chestnut flavor slowly expanded across my palate with surprising depth. The natural sweetness was gentle yet unforgettable, quiet, but with a presence that lingers.

From that moment, I was completely captivated.

Kurizuki is a wagashi I can confidently recommend to travelers seeking authentic regional flavors, and to buyers looking for products with a compelling story and genuine craftsmanship.

After a long day of work, it’s perfect with a cup of coffee. a small moment of comfort that helps you breathe again.

It pairs beautifully not only with matcha and green tea, but also with roasted brown rice tea, coffee, and black tea, making it accessible to international tastes.

Where Can You Buy It?

Kurizuki is available at:

• Confectionery shops within Kumamoto Prefecture and across Kyushu

• Domestic online shops

And here is good news for travelers who may not be visiting Kyushu:

You can also buy it at the Kumamoto Antenna Shop in Ginza, Tokyo—a specialty store that carries regional products from Kumamoto. When I crave Kurizuki, I often go to Ginza to buy it myself.

Shelf life: approx. 4–5 weeks

Price: 6 pieces: 1,361 yen ≈ 8.6 USD, 12 pieces: 2,722 yen ≈ 17.2 USD
