Koshu Yamanashi Shimooara Kajo 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-Eor period to the Showa era. The most striking feature is the preservation of traditional houses and unique structures known as 'silkworm rooms' (kaikoshitsu), which were built alongside the development of the sericulture (silk farming) industry. These buildings exist in perfect harmony with the surrounding farmland and natural environment.
The region has a deep-rooted history tied to the prosperity of the silk industry. As sericulture became the backbone of the local economy from the mid-Edo period through the Showa era, a distinct architectural style emerged to support this industry. In 2015, the area was officially recognized by the Council for Cultural Affairs as a significant preservation district. The buildings within the settlement are not merely old structures; they are vital cultural heritages that tell the story of Japan's agricultural and industrial evolution.
Visitors can find a variety of traditional houses scattered throughout the settlement, each reflecting the lifestyle of the era when sericulture was at its peak. By observing the specific structures of the silkworm rooms, you can visually grasp the industrial culture of the past. The entire village is beautifully integrated with the natural landscape of the mountain foothills, offering a quintessential view of a traditional Japanese rural landscape where history and nature intertwine.
As this is an outdoor preservation district, there are no specific opening or closing hours. We recommend exploring the area during daylight hours for the best visibility. The scenery changes beautifully with the seasons, allowing you to observe the changing colors of the natural environment and the timeless appearance of the traditional village throughout the year.
Walking through the narrow paths of the settlement allows for a peaceful stroll where you can observe the traces of traditional Japanese architecture and the remnants of the silk-producing culture. It is a wonderful opportunity to trace the historical way of life in a Japanese rural community while admiring the unique structural designs of the preserved houses.
Koshu City is dotted with various other historical sites and spots rich in nature. You can easily incorporate this visit into a larger travel route that explores the historical landscapes and agricultural heritage of Yamanashi Prefecture.
The settlement consists of outdoor paths and natural environments. We highly recommend wearing comfortable walking shoes. As this is a living community with residents and preserved historical structures, please respect the local lifestyle and maintain a quiet, respectful presence during your visit.
