Chapter 15 - Sandy road:
I just went down route 134 and found that the place shown in [v2, p120] looks to be here, a little east of the hammer-shaped point:

Sensei mentions that there used to be traffic jams. The western part of route 134 is known for its heavy traffic, "Enoshima traffic jam".
The road is already a little sandy. There are pine trees planted along the road to prevent sand shifting.
