A comfortable sleep for you. Committed to manufacturing mattresses for twenty years. Everything for customer's sleep.

KOKI INTERNATIONAL CORP. has been continuously manufacturing mattresses for a quarter century.
When we were first established, mattresses were only decorative products paired with beds. However, as beds have become common among Japanese, KOKI INTERNATIONAL CORP. has repeated the research / improvement process in pursuit of mattresses suitable to Japanese preferences and culture with the belief that "beds" to which people entrust their bodies and 1/3 of their lifetime are very important.
Furthermore, within the various types of mattresses currently available, we continue to search for "the mattress that suits Japanese " and manufacture specialized mattresses.
