I am flying through a tunnel with traffic moving on the left side of the road. The road markings consist of a solid white line separating the lanes, which is common in many regions. The vehicle ahead is a boxy minivan, a style very popular in Japan. The tunnel walls are plain concrete with uniform lighting. I suspect this is Japan, likely in a major urban area. I am moderately sure.

then: forward

The tunnel environment remains consistent, with left-side traffic flow confirming my previous observation. The white minivan ahead is a very common sight in Japan, and the clean, well-maintained tunnel infrastructure is typical of Japanese urban road networks. I am confident this is Japan, likely within a major metropolitan area like Tokyo or Osaka. I am fairly sure.
