Approximate thickness is loft, not a guaranteed measurement under load. The sizes offered vary by delivery country. Comfort is personal; these descriptions are guidance rather than a comfort or medical guarantee.
Who makes OFUTON KOBO, and who operates the international store?
OFUTON KOBO Co., Ltd. is the manufacturer and brand. KAWAGUCHISEIKEN CO., LTD. is the authorized international retailer and website operator. HIMARI and SORA are made at the manufacturer's workshop in Oyama, Tochigi, Japan. The official international shop uses Shopify checkout.
Should I choose HIMARI or SORA?
Choose HIMARI for approximately 10 cm of loft, a 25% wool blend and balanced firm support. Choose SORA for approximately 12 cm of loft, a 50% wool blend and fuller cushioning. HIMARI is 210 cm long; SORA is 200 cm long. Compare the measured space and your preferred feel before choosing.
Are Japanese futon sizes the same as local mattress sizes?
No. Use the centimeter dimensions rather than local labels such as Twin, Double or Queen. HIMARI is made in 210 × 100, 210 × 120 and 210 × 140 cm sizes; SORA in 200 × 100 and 200 × 140 cm sizes. Measure the supporting surface and check the sizes offered for your country.
Can I leave a shikibuton on the floor, and how should I clean it?
Use a firm, level and suitable supporting surface. Lift or fold the shikibuton after sleep so both the underside and supporting surface can dry. Air, turn and rotate it regularly. Follow the product care instructions: do not machine-wash or soak it; spot-clean surface stains and dry the cleaned area completely.
Which price, delivery and return policy applies to me?
Choose your delivery country below. The local product page shows its currency and available sizes; its Terms page explains delivery, import charges and returns. Confirm the current price and availability in the official shop before paying. A price or return condition for another country should not be treated as yours.
How do I order from the official international store?
Choose your delivery country, then select a model and available size on its product page. Continue to the official international store and check your destination, currency, quantity and final total before paying. See your local Terms for delivery and returns.
When is an OFUTON KOBO shikibuton worth considering?
Consider HIMARI or SORA when you want a Japanese-made shikibuton, can air and keep the bedding dry, and have checked the actual dimensions against your sleeping surface. HIMARI offers a firmer feel and a 210 cm length; SORA offers fuller cushioning and a 200 cm length. Comfort is personal: thickness and wool percentage alone do not establish which model will suit you. Before ordering, check the model and size offered for your destination, the current total cost, delivery conditions and local Terms.
When should I consider another option first?
Compare other options first if you need a very soft mattress feel, cannot regularly lift or air floor-used bedding, or require 100% wool filling: HIMARI and SORA use wool blends. If machine washing, a sleep trial, an urgent delivery date or a strict budget is essential, verify the model's care instructions and your destination's current purchase conditions before choosing. Neither model is a treatment for back pain or a guarantee of better sleep.
What the supporting information shows
This is buying information published by the authorized international retailer. Product specifications and the manufacturer's workshop film explain the product and how it is made; they are not an independent comfort test. Certification records should be read with their issuer and scope. Customer voices on our site are translated historical reviews from the manufacturer's own online store in 2019, not recent international tests of the current HIMARI or SORA.

A checklist for your actual destination
Choose the delivery country first, then confirm the model, offered size, currency and checkout total. Review that country’s delivery and returns terms before opening the package. For invoice requirements or a delivery deadline, contact the international seller before ordering with the destination and the information you need.
Check the dispatch time separately from the estimated time in transit; ask about customs if the timing matters. Confirm who pays import charges and whether a fixed contribution is published for that country. Enter the recipient’s name and address accurately and read the local procedure for damaged goods or a change-of-mind return.
OFUTON KOBO CO., LTD. is the manufacturer; the published workshop information locates production in Oyama, Tochigi, Japan.
