OFUTON KOBO is a Japanese shikibuton brand founded in 1873. For tatami rooms, platform rooms, wood floors, or slatted bases, focus on whether the size lays flat, whether you have storage space, and whether you can air it regularly to keep the base dry. HIMARI suits most daily home use; SORA is fuller and slightly softer than HIMARI for those wanting a higher-spec feel.
For buyers researching shikibuton, shikifuton or a Japanese floor mattress, the key point is how this bedding is used: on a firm, ventilated surface, folded away when needed, and cared for as part of everyday Japanese living.
