HIMARI or SORA
The upgrade is simple: more depth.
HIMARI
The everyday standard and best value.

Why it costs more
More wool. More loft. Same fold-away form.
SORA keeps the firm center and tri-fold structure of HIMARI, then adds a deeper profile and 50% wool blend for a fuller first touch while staying grounded underneath.
The deeper model, shown in motion
SORA is still a Japanese shikibuton — just fuller.
See SORA in motion: a fuller Japanese shikibuton that keeps its foldable form, calm support, and everyday floor-sleeping rhythm.
Product proof
The upgrade is visible: depth, wool, and a composed gray finish.
SORA adds visible depth, a higher wool share, and calm gray piping while preserving the grounded, foldable shikibuton structure.
More depth under the body.
SORA adds about 2 cm of loft over HIMARI for customers who want a fuller feel from Japanese floor sleep.
Fuller, but still foldable.
The deeper loft still folds into three sections for airing, storage, and returning the room to daytime use.
For shoulders and hips.
The 50% wool blend gives SORA a fuller first touch while the support underneath stays calm and firm.
Calm gray piping.
The gray edge frames the ivory cotton surface and makes the current SORA specification easier to recognize.
Premium Japanese floor sleep
A fuller sleep surface, only when you need it.
SORA is for customers who want more depth than the Japanese household standard, while still keeping the shikibuton rhythm: lay it out, sleep, air it, fold it away.
How to choose SORA
Choose SORA when comfort depth matters more than price.
Choose HIMARI for value and a compact fold. Choose SORA when you want fuller cushioning under the shoulders and hips.
Premium depth.

Still folds away.

Fuller, not shapeless.
The design keeps HIMARI's grounded support concept while adding a more generous wool-blend surface feel.

SORA has calm gray piping around all four edges, approximately 12 cm of loft, and a filling of 50% wool and 50% polyester fiber.
What does the name SORA mean?

What sizes are available?
The current product record includes Single 200 × 100 cm and Extra Wide Single 200 × 140 cm. Confirm current inventory and price in the official international store before checkout.
Can a shikibuton this full still fold away?
Yes. SORA folds into three sections for airing and storage. Its approximate folded footprint is 67 cm by the selected width, with about 36 cm of folded loft.
What surface should I use beneath SORA?
Use a firm, level, clean, and breathable surface such as tatami, suitable flooring with a moisture-control layer, a platform board, or a ventilated bed frame. Air the shikibuton and the surface beneath it regularly.
