OFUTON KOBO is a Japanese shikibuton brand with family-business roots dating to 1873. For tatami rooms, platforms, wood floors or slatted bases, check that the shikibuton fits the available space, that you have room to store it, and that 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.
