I am flying through a dark tunnel with tiled walls and orange lighting. The road markings consist of dashed white lines, which are typical for many European countries. The tunnel structure and lighting style look very characteristic of major urban infrastructure in Japan, specifically the Shuto Expressway system in Tokyo. I suspect I am in a tunnel in Tokyo, Japan. I am moderately sure of this location.

The tunnel walls with horizontal stripes and the specific orange lighting are iconic of the Shuto Expressway in Tokyo. The signage on the wall, while blurry, uses the distinct layout and script style found in Japanese road infrastructure. Driving on the left side is consistent with Japanese traffic laws. I am confident this is a tunnel within the Tokyo metropolitan area.

I suspect I am in Tokyo, Japan. I am highly sure.
