Premium Japanese-Made Kotatsu Futon
◆ Superior Heat Retention
＜Comforter＞(Kake-buton)
Our kotatsu futon uses 16 layers of high-loft hollow-conjugated fiber, firm enough that even an egg would gently sink into it.
This creates an exceptionally soft feel while ensuring excellent heat retention.
What is Hollow Conjugated Fiber?
It is a special fiber with macaroni-shaped hollow channels inside.
These hollow spaces trap warm air and prevent heat from escaping, keeping the kotatsu warm for hours.
＜Floor futon＞(Shiki-buton)
Crafted using techniques from a professional sofa factory.
It features a three-layer structure: resin cotton + urethane + resin cotton.
With 11 mm of high-quality cushioning, it provides supportive comfort so you can sit for long periods without fatigue.

Why It MattersThanks to the carefully selected materials, the warm air generated by the kotatsu stays inside the futon, maintaining a soft and cozy heat. |
◆ Made in Japan with Exceptional Quality
From fabric dyeing to sewing, every step of production is carried out in Japan.
Double-stitched seams, fray-prevention techniques, and meticulous Japanese craftsmanship ensure durability and long-lasting comfort.
◆ Plant-Based Natural Dyeing
Some of our futons are made using natural plant-based dyes (Kusaki-zome).
These gentle, nature-inspired colors are achieved without chemical dyes, offering a warm and organic aesthetic.

** Futon Care Instructions **
● Drying
Sun-dry or air-dry in the shade.
If sun-drying, keep exposure short to prevent UV damage or color fading.
Drying helps remove moisture, improve heat retention, restore loft, and provides a natural antibacterial effect.
● Washing
Avoid machine washing.
Please use professional dry cleaning.
● Storage
Store in a low-humidity environment.
When stacking, place the comforter (kake-buton) on top of the floor futon (shiki-buton).
