Guide
Koshu Shimoyamadawara Kamijo is a designated "Preservation District for Groups of Traditional Buildings" located in Koshu City, Yamanashi Prefecture. This mountain village, situated on the foothills overlooking the Kofu Basin, preserves architectural styles ranging from the mid-Edo period to the Showa era. A defining feature of this area is the presence of traditional houses and unique structures known as "kaikoshitsu" (silkworm rooms), which were built to support the flourishing silk industry. These buildings exist in perfect harmony with the surrounding fields and natural environment.
The region boasts a rich history tied to the prosperity of the sericulture (silk farming) industry. As the silk trade grew from the mid-Eod period through the Showa era, a distinct architectural style emerged to support the local economy. In 2015, the area was officially recognized by the national government as a Preservation District for Groups of Traditional Buildings. The structures within the settlement are more than just old buildings; they are vital cultural assets that tell the story of Japan's agricultural and industrial history.
As you walk through the settlement, you will encounter various traditional houses that reflect the lifestyle of the people who once worked in the silk industry. The presence of specialized structures like the silkworm rooms provides a visual and tangible connection to the industrial culture of the past. The entire area offers a quintessential Japanese rural landscape, where historical architecture blends seamlessly with the natural scenery of the mountain foothills and local farmland.
Since this is an outdoor preservation district, there are no specific opening hours or entrance gates. We recommend visiting during daylight hours for the best experience. The scenery changes beautifully with the seasons, allowing you to observe the village in different lights—from the lush greenery of summer to the serene atmosphere of other seasons.
Enjoy a peaceful stroll through the village paths to observe the traces of Japan's traditional architectural styles and the legacy of the silk-rearing culture. Walking through these paths offers a unique opportunity to trace the historical way of life in a Japanese rural setting.
