CURVESCOUT / MOTORCYCLE RIDE
Ordered leg totals agree within rounding. Stop distances are approximate sums of rounded legs. Stops, delays, approach and any separate return travel add time. Basis: producer-declared routed record.
Reading history stays on this device. My road watch requires a separate selection; opening it does not subscribe this ride.
Distance and riding time are measured on the routed road. Check local closures and conditions before you ride.
154 km from Sakai-nakajima to Sakai-nakajima, about 3 h 17 of riding. On the way it passes Takayama-sha Sericulture School, Arafune Cold Storage and back through Takayama-sha Sericulture School. The stored terrain estimate reaches about 1,200 m; a measured road-elevation profile is not available. It was put together for the scenery rather than the shortest line.
Silk transformed modern Japan, and Gunma Prefecture was its heartland. In the village of Shimamura, now part of Isesaki, on the north bank of the Tone River, stands the farmhouse of Tajima Yahei, a sericulturist who developed a method of raising silkworms in the nineteenth century. He built a two-storey house with a ventilation structure on the roof, allowing air to circulate through the upper floor where the silkworms were kept, and his design was widely copied across Japan.

Tajima Yahei Sericulture Farm is where the day begins. Next is Takayama-sha Sericulture School.
Silk built modern Japan, and the hills of Gunma prefecture were its engine room. In the second half of the nineteenth century, farmhouses across this region raised silkworms on the upper floors, and the quality of the cocoons decided the fortunes of families and, eventually, of the nation's exports. At the Takayama-sha site in Fujioka, a farmer named Takayama Chōgorō developed a method of raising silkworms that balanced ventilation and temperature, and he trained students from across Japan in his large farmhouse. You can still see the building, with its distinctive roof vents running along the ridge, designed to let warm, moist air escape.

Takayama-sha Sericulture School comes up about 28 km into the recorded legs. Next is Arafune Cold Storage.
High in the mountains of southwestern Gunma, near the border with Nagano, a series of stone-walled pits sit among the trees on a hillside. They look like ruins, and in a sense they are, but in their day they were cutting-edge technology. The Arafune cold storage, built in the early twentieth century, used the cold air flowing out of crevices in a rocky slope, a natural wind cave or fuketsu, to keep silkworm eggs cool and delay their hatching. This allowed silk farmers to raise several batches of silkworms a year instead of just one, greatly increasing production. At its peak, the facility stored eggs for farmers from across Japan and even abroad. It is part of the UNESCO listing of the Tomioka Silk Mill and Related Sites, inscribed in 2014, which tells the story of how Japan became the world's largest exporter of raw silk.
