ひわだや List of Products and Services

Hinoki bark roofing is a traditional Japanese roofing technique that uses materials shaped from the bark of hinoki trees. It allows for elegant curves and a sense of weightiness in the eaves, and is primarily seen in important cultural properties today. Since only the bark is harvested from standing hinoki trees, it is considered an environmentally friendly method. However, the decreasing availability of harvestable hinoki, the aging and decline of craftsmen (known as "motokawashi"), and those who produce the products (known as "hiwadakoshiraeshi") have made securing materials increasingly difficult. "Hiwadaya Co., Ltd." was incorporated in 1994, continuing the tradition of "Hiwadaya," which has existed since the Tenpo era (1830s). The representative, Makoto Sasaki, is the only hinoki bark roofer in Yamaguchi Prefecture. Hiwadaya Co., Ltd. will continue to preserve and pass on the unique traditional architectural culture of hinoki bark roofing in Japan.
