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.
317 km from Nikkō to Nikkō, about 5 h 44 of riding. It goes by way of Tajima Yahei Sericulture Farm, Takayama-sha Sericulture School, Tomioka Silk Mill and Related Sites and Tomioka Silk Mill. The stored terrain estimate reaches about 1,200 m; a measured road-elevation profile is not available. A steady touring day rather than a sprint.
Waypoint introductions and full write-ups
1. Nikko
Nikko is where Tokugawa Ieyasu was laid to rest, and the town lives with the weight of that. Ieyasu, who founded the shogunate that ruled Japan for two and a half centuries, died in 1616 and was enshrined here in the mountains north of Tokyo, and the Toshogu shrine, completed a year later and enlarged by his grandson, is a riot of gold leaf, carving and colour, quite unlike the restraint most people associate with Japanese temples. The famous carving of the three monkeys, hear no evil, see no evil, speak no evil, is here.

Nikko is where the day begins. Next is Tajima Yahei Sericulture Farm.
2. Tajima Yahei Sericulture Farm
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.

Planning note
Tajima Yahei Sericulture Farm comes up about 106 km into the recorded legs. Next is Takayama-sha Sericulture School.
3. 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.

Planning note
At least about 134 km into the recorded legs you reach Takayama-sha Sericulture School. Next is Tomioka Silk Mill and Related Sites.
4. Tomioka Silk Mill and Related Sites
In 1872, barely four years after the Meiji Restoration had ended the rule of the shoguns, Japan's new government opened a model silk-reeling mill in the small town of Tomioka in Gunma prefecture. It hired a French engineer, Paul Brunat, imported French machinery, and recruited young women from across the country to learn the new techniques and take them home. The long brick buildings, a curious mix of Japanese timber framing and European brick, still stand, and the mill operated until 1987. In 2014 it was inscribed on the UNESCO list together with related sericulture sites, such as farms where silkworm rearing methods were improved and a cold storage cave used to control the hatching of eggs.

Planning note
Tomioka Silk Mill and Related Sites, about halfway. Next is Tomioka Silk Mill.
5. Tomioka Silk Mill
Tomioka Silk Mill is a long, low brick building with a timber frame, and it looks stranger than it is. In 1872, only a few years after the Meiji government opened Japan to the West, the state built this factory to produce silk by modern methods and sold it abroad to pay for the country's modernisation. A French engineer, Paul Brunat, designed it and hired French instructors, and the brick, laid in a pattern known as Flemish bond, was made locally by workers who had never seen a brick building before. The cocoon warehouses, with their sturdy roof frames, are still among the biggest wooden-framed brick buildings in Japan.
