I'll never buy any other type
"I've used buckwheat pillows for nearly 10 years and I'll never buy any other type. They are comfortable and supportive in any sleep position. Waking up with a stiff neck is a thing of the past."

A buckwheat pillow is filled with natural hulls instead of foam or fiber. The hulls move with you as you settle in, creating a firm, adjustable feel with steady airflow through the pillow.
Choose Japanese Plus (14" x 20") if you like a more compact pillow with a focused, traditional buckwheat feel.
Choose Standard (20" x 26") if you prefer more surface area or want something closer to the size of a regular bed pillow.
Both sizes are adjustable. The better choice simply depends on whether you prefer a smaller, more precise pillow or a larger sleeping surface.
Start with the pillow as it arrives, then remove a small amount of hulls if it feels too high or too firm. Give yourself a few nights to fine tune the fill until your head and neck feel properly supported.
When lying down, gently shape the hulls into the curve of your neck instead of using the pillow completely flat.
Remove any washable cover components according to your pillow model before cleaning. The buckwheat hull filling should always stay dry.
Regular airing and proper cover care will help keep your pillow feeling clean, fresh, and ready for nightly use.

Real feedback from 10 sleepers who returned to the traditional Japanese Sobakawa way.
A Sobakawa is the original Japanese buckwheat pillow. It features a simple, durable cotton shell filled with 100% buckwheat hulls. The design prioritizes firm, moldable support and natural airflow—a tradition trusted for centuries for better sleep and posture.
This pillow is ideal for purists and anyone seeking extra-firm, traditional support. If you're a side or back sleeper who wants a no-frills pillow that locks in place, this is for you. If you prefer a softer, more cushioned feel, our Signature Buckwheat Pillow with its padded bamboo cover might be a better fit.
The main difference is the cover. The Classic Sobakawa has a single, durable cotton twill shell for a direct and firm feel. The Signature Model features a two-layer design with a soft, quilted bamboo outer cover that adds cushioning and muffles sound. Think of the Classic as the authentic, extra-firm original and the Signature as a modern, luxury version.
It's simple. The pillow has a heavy-duty YKK zipper, allowing you to easily add or remove buckwheat hulls. Take some out for a softer, lower pillow, or keep it full for maximum firm support. We intentionally overstuff our pillows so you have plenty of hulls to customize your perfect loft. For full guidance, read our adjustment article →
The cotton shell is fully machine washable. Just follow these steps:
1. Unzip the cover and pour the buckwheat hulls into a box or bag.
2. Machine wash the empty shell on a gentle cycle and air dry completely.
Important: Never get the buckwheat hulls wet. To refresh them, just spread them out in the sun for a few hours. Read our full cleaning guide for more details.
