Whether you’re a foodie, a culture enthusiast, or planning your autumn trip to Japan, discovering chestnuts will add a rich new flavor to your journey.
1. What is Chestnut?
Chestnut, or "kuri," is the fruit of the deciduous broadleaf Castanea tree, recognized as a staple in Japanese diets since ancient times. The native variety, "Waguri," offers the perfect balance of size, sweetness, and texture, inviting you to savor autumn’s bounty in a uniquely Japanese way.
Imagine peeling away the spiny burr and hard shell to reveal a golden nut with a delicate, fluffy texture and natural sweetness—as comforting as the crisp autumn breeze rustling through Japan’s forests.
2. What is Waguri (Japanese Chestnut)?
"Waguri," native Japanese chestnuts, grow wild and have become beloved for their large size and gentle sweetness. Unlike European or Chinese chestnuts, their thick skin makes peeling a treasured seasonal ritual—a moment to connect with tradition and family during autumn.
From comforting chestnut rice to the golden kuri kinton, chestnuts flavor Japan’s autumn and festive tables alike.
