I like this speculation. Shinjuku setting would be awesome.

Going to double post since my post is basically buried. Here's a hint
Dotonbori is three minutes away from Namba Station in Osaka. It's a city that never sleeps, basically, and a huge tourist attraction. It's also near Minami, which is another district, and the Japanese word for "south"
The JR East Station is one of the biggest stations in all of Tokyo, and is very big around Shinjuku. In Shinjuku, it is known as one of the busiest train stations in the world to some, even going as far as being recognized in the Guinness Book of World Records.
The Sakae Station is located in the Naka ward of Nagoya and in the city of Aichi, and is a fairly nice station. I couldn't find much info about it, though...
The Nishitetsu Fukuoka (Tenjin) station is another big station that is also home to a small shopping center of sorts.
The Sendai Station is known as the biggest station in Sendai, and is home to the Sendai Subway Namboku Line. It was affected in the 2011 Touhoku earthquake and tsunami. Not much more info I can find on it, sadly...
The Sapporo Chikagai, located near Odori, is home to an underground shopping center. I couldn't find much more information, but I did find that it is near some shopping centers such as Aurora City and Pole Town.
Now, to those who also speak Japanese, do you get it yet?
The answer is These are directions. North and south is Namboku in Japanese. North alone is Kita, and south alone is Minami. Combined is Namboku, which means north and south, Naka is middle, Chikagai is underground. Nishi is west. JR East is well, east. Dotonbori is near Minami, which means south. Chuo-ku, where Odori is, also means "center" Seeing something here?
Now, let's push this theory up to eleven. Shinjuku is the only place that is a ward within itself. Shinjuku is divided into 6 wards, each in different directions. What are the directions of these wards? North, south, east, west, with Shinjuku being the one in the center/middle. Shinjuku also has an underground district, I believe.
