Sericulture Tools of Shōkawa: 230 Pieces That Tell the Story of Silk in the Gassho-Zukuri Lofts
High in the mountains of Gifu Prefecture, in the former village of Shōkawa, families once climbed into the steep timber lofts of their thatched homes every spring to tend tiny silkworms. The Sericulture Tools of Shōkawa — a 230-piece collection designated as an Important Tangible Folk Cultural Property in 1963 — preserves the trays, frames, baskets, and processing implements that made this mountain livelihood possible. Today the collection is housed at the Hida Folk Village in Takayama City, where visitors can step inside a relocated gassho-zukuri farmhouse and see how an entire upper story was once dedicated to silk.
The Mountain Village That Lived on Silkworms
The former village of Shōkawa — absorbed into Takayama City in a 2005 municipal merger — sits in a steep, snow-heavy corner of the Hida region, on the upper reaches of the Shōgawa River. Its proximity to the Shirakawa-gō area meant its farmhouses shared the famous gassho-zukuri ("hands-in-prayer") style of building, with sharply pitched thatched roofs that shed deep winter snow and shelter spacious attics underneath.
The land here was never generous to rice farmers. Arable fields were narrow and the growing season short, so households relied on alternative industries to earn the cash they needed to buy grain. From the Edo period onward, two industries supported the gassho-zukuri economy: the production of enshō (saltpetre for gunpowder), and sericulture — the raising of silkworms for their cocoons. As enshō production declined in the Meiji era, silk became even more central. The wide, well-ventilated attic floors of the gassho-zukuri homes turned out to be almost perfectly designed for raising silkworms at scale.
How the Collection Came Together
The Sericulture Tools of Shōkawa were assembled in the late 1950s under remarkable circumstances. The construction of the Miboro Dam was about to submerge several villages on the Shōgawa River, and a campaign began to rescue significant farmhouses before they were lost forever. One of these — the Wakayama House (旧若山家住宅), built in 1797 — was carefully dismantled and reassembled at a new outdoor museum in Takayama in 1959. This relocation marked the founding of what is now the Hida Folk Village.
When the Wakayama House was rebuilt, its second and third floors were left intact as a working sericulture space, exactly as the family had used them. The tools that had filled those lofts — alongside implements collected from other Shōkawa households — were gathered into a single ethnographic collection. In 1963 the assemblage of 230 items was designated by the national government as an Important Tangible Folk Cultural Property, recognizing it as one of the most complete surviving records of mountain-village silk culture in Japan.
Why This Collection Was Designated
Folk cultural property designations protect not single masterpieces but coherent groups of everyday objects that document a way of life. The Sericulture Tools of Shōkawa qualify on three counts.
First, the collection is remarkably complete. Its 230 pieces are organized into 207 items related to silkworm rearing and 23 related to cocoon processing — covering nearly every stage from hatching to harvest. Few surviving collections preserve such a continuous picture of the work.
Second, the tools are tied directly to their architectural setting. Because the Wakayama House was relocated with its attic sericulture rooms intact, the collection retains the spatial logic of mountain silk production in a way that a museum case alone cannot convey.
Third, the collection captures regional character. Sericulture in the heavy-snow gassho-zukuri zone differed from that of the Kantō plains or Nagano basins: the work was performed in vertically stacked lofts, families were unusually large, and certain tools and techniques were adapted to the cold, humid mountain climate. These regional traits give the collection unique ethnographic value.
Inside the Tools Themselves
Most visitors are surprised by how varied a "tool" can be. The collection ranges from the very small to the architecturally embedded, and each item answers to a specific moment in the silkworm's roughly one-month life cycle.
The rearing tools include flat woven trays known as sanpaku, used to spread out the tiny silkworms and the mulberry leaves they eat; soft brushes made from feathers, used to sweep newly hatched larvae from their egg sheets onto the trays; and rush-grass nets called i-ami, laid over the trays to lift the worms cleanly when frass and leaf scraps need to be cleared. There are also temperature-control implements, mulberry-cutting knives and boards, and tiered wooden shelving on which dozens of trays could be stored upright in a single attic room.
The cocoon-processing tools document the next stage. When the silkworms stopped eating and prepared to spin, they were moved into mabushi — straw or paper compartments that gave each worm its own small chamber to spin in. The collection includes mabushi-oriki (devices for folding straw mabushi) and kebatori-ki (machines that removed the loose floss fibers from the outside of each finished cocoon). Together these tools show the full path from a feeding silkworm to a sorted, ready-to-sell cocoon.
Highlights for Visitors
The collection is displayed in context at the Hida Folk Village (Hida no Sato), an open-air ethnographic museum on a wooded hillside southwest of central Takayama. Several features make the visit worthwhile beyond the tools alone.
The relocated farmhouses themselves are the headline attraction. More than 30 buildings have been reassembled across the site, including four nationally designated Important Cultural Properties. Visitors can climb into the lofts of gassho-zukuri houses and see, from inside, why these soaring roofs were so well suited to silkworm work.
The seasonal atmosphere transforms the experience. In spring, cherry blossoms frame the thatched roofs; in summer, the mountain air is cool under deep eaves; in autumn, the maples around Goami Pond turn brilliant; and in winter, deep snow recreates the conditions that shaped the gassho-zukuri form in the first place. Selected evenings see illuminations that throw the silhouettes of the houses into striking relief.
Hands-on demonstrations are often available depending on the day. Visitors can watch craftspeople at work in straw weaving, sashiko stitching, lacquerware, weaving, and dyeing — sister crafts that grew alongside silk in the Hida economy.
Around the Hida Folk Village
The folk village sits just outside the historic core of Takayama, an area rich with attractions that pair naturally with a visit to the Sericulture Tools of Shōkawa.
The Sanmachi old town, with its preserved Edo-period merchant houses, sake breweries, and morning markets, is roughly fifteen minutes away by bus or car. The Takayama Jin'ya, a rare surviving Edo-period government office, lies in the same district. For those interested in folk performance, the Takayama Yatai Kaikan displays the elaborate festival floats of the Takayama Matsuri, themselves designated cultural property.
Further afield, a day trip to the Shirakawa-gō UNESCO World Heritage village makes the connection between tools and architecture even more vivid: the same kind of gassho-zukuri houses that gave up their lofts to silkworms still stand and are still lived in. Local buses connect Takayama to Shirakawa-gō in around 50 minutes.

Q&A
- Where exactly can I see the Sericulture Tools of Shōkawa?
- The collection is housed at the Hida Folk Village (Hida no Sato), at 1-590 Kamiokamoto-cho, Takayama City, Gifu Prefecture. The site is an open-air museum, and many tools are displayed inside relocated gassho-zukuri farmhouses where they were originally used.
- When was the collection designated, and what is its official status?
- The collection was designated an Important Tangible Folk Cultural Property by the national government on May 15, 1963. It consists of 230 items in total, owned by Takayama City.
- Is sericulture still practiced in Shōkawa today?
- Active mountain-village sericulture has long since ended in the area. It declined sharply from the late Meiji period onward, as the large extended families needed to staff the work broke up and as cheaper silk from elsewhere reshaped the market. The collection is a record of that vanished economy.
- How long should I plan for a visit?
- Most visitors spend between two and three hours at the Hida Folk Village. A full tour of the relocated farmhouses, including the upper-floor sericulture spaces and the connected workshop demonstrations, comfortably fills half a day.
- Is the site accessible without Japanese language skills?
- The Hida Folk Village provides multilingual signage at major buildings, including English. The visual nature of the architecture and tools also makes the site rewarding even without detailed reading; bringing a guidebook or downloading the official site map in advance can help.
