The Doshimichi is a legend among Tokyo motorcyclists. It is Route 413, a mountain road that leaves the Sagami plain near Sagamihara and climbs west into the Tanzawa and Yamanashi hills, following the valley of the Doshi river toward the village of Doshi. The name simply means the road to Doshi, and it has been a favourite for decades, with twisting bends through forest, steep slopes and the occasional tunnel, and a good number of bikers on weekends.
This is a landscape of cedar plantations, small farms and narrow valleys, with steep slopes cut by streams. Lake Sagami, a reservoir on the river of the same name, lies nearby, and the roads around it are quiet.
Doshi village is known for its clear spring water, and there are several places where you can fill a bottle from public springs. The water is cold and tastes of stone, and it is a good reason to stop. The village itself is small, with a handful of shops, and there is a park with a stream, popular with families in summer. In winter, snow can fall on the upper part of the road and ice can form in shaded corners, so be careful.
Do not expect to ride fast. Police patrol the Doshimichi regularly, particularly on weekends, speed limits are strict, and fines are high. The best approach is to enjoy the rhythm of the road and the scenery, and to stop for a break at one of the roadside parking areas. Fuel is available in Uenohara and Otsuki, each with around twenty-eight to thirty-one thousand people, and in Sagamihara, and it is wise to fill up before entering the mountains. Early morning is best, when traffic is light, and the forest smells of damp earth and cedar. Autumn brings red and gold leaves, and the air is clear.
