Kuro & Rin is a two-person, Japanese-inspired homeware studio. We don't chase catalogues. We write about slow living, and we curate a tight edit of honest pieces — bought and lived with before we ever recommend them.
静けさや綿の匂いに夜が明く
What we believe
Cotton, linen, indigo, wood. Materials that soften with use and age instead of wearing out.
Fewer objects, better made. Space to breathe, sleep, and wake without noise.
We say when we haven't tried something. Everything featured is lived with first.
The featured object
Our first pick is the J-Life International Shikifuton — an authentic Japanese floor mattress made to traditional specification in 100% American-grown cotton, with a removable Japanese cover. No foam, no innersprings. Just cotton, cloth, and craft.

敷布団 · The making of the Shikifuton
The J-Life Shikifuton is the single object our storefront is built around — an authentic Japanese floor mattress, made to traditional specification in pure cotton. This is what goes into one.
一 · Ichi — The fibre
A true shikibuton (敷布団) is defined by what it doesn't contain — no foam, no springs, no synthetic batting. J-Life fills each futon with 100% American-grown cotton, layered by hand to a consistent density that supports the spine on a flat surface. The cotton breathes, wicks moisture, and softens with use rather than compressing into ruts the way foam does.
二 · Ni — The shell
The inner shell is unbleached cotton duck — a dense, tightly-woven canvas that holds the cotton batting firm and lets the futon be aired in the sun the traditional way. Naturally-derived boron is used to meet US fire-retardant standards, avoiding the chemical flame retardants used in conventional American mattresses.
三 · San — The cover
Fitted over the shell is a custom zippered cover handmade of high-quality 100% cotton imported from Japan. The solid white colourway is a crisp, honest canvas — pair it with a tatami mat or a low platform bed. When it needs washing, unzip and launder the cover; the futon itself only needs airing.

四 · Shi — The make
J-Life International produces each shikifuton to painstaking traditional Japanese specifications in the United States, with Japanese fabric imported for the covers. Please allow 5–7 days for production before shipping — every futon is filled and finished after you order, not pulled from a warehouse stack.
五 · Go — The sleep
A firm sleep surface encourages a neutral spine — many chiropractors recommend a shikifuton for lower-back complaints. Choose the 3" super-firm for the most traditional Japanese feel, or the popular 4" traditional for a softer landing. Intended for use directly on tatami, a hardwood floor, or a flat platform bed — never on a folding American-style futon frame.
六 · Roku — With time
The Japanese ritual of futon-hoshi — airing the futon in direct sunlight every few weeks — keeps the cotton lofty, dry, and quietly fragrant. Fold it away in the morning; unroll it at night. This is how a bedroom becomes a room again, and how one honest object earns its place for the next twenty years.
