New to Buckwheat Pillows?
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.
Most first-time users need a few nights to dial in the right fill level and shape. Read how long it takes to get used to a buckwheat pillow.
Choosing the Right Size
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.
Adjusting the Fill for Better Support
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.
If the pillow feels too high, too firm, or too noisy, it usually needs a small setup change before you judge it. Read the guide to common buckwheat pillow mistakes.
Keeping Your Pillow Fresh
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.

- Highly effective for sleepers who need firmer support around the neck, shoulders, and upper spine.
Fully Adjustable Comfort
- Simply unzip the durable case to add or remove hulls, fine-tuning the height and firmness to your specific body type.
- Removing hulls makes the pillow softer and more moldable; adding hulls makes it firmer and more supportive. Not sure where to start? Read our step-by-step usage guide.

Questions & Answers
What is a Sobakawa pillow?
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.
Who is this Classic pillow best for?
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.
How is this different from your Signature pillow?
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.
How do I adjust the loft and firmness?
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 →
How do I wash and care for it?
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.
