Raccoon Lane (Tanuki Kouji) is a 7 block long covered shopping arcade (全蓋アーケード) in Sapporo.  Except for the westernmost block (7-chome), the current structure dates to 1982 (Note 1), and it has been fully covered since 1960 (Note 2).

The arcade runs parallel to Odori Park (five blocks south of the park):

The arcade also ties into an underground pedestrian space which runs one mile north-south, from Susukino Station at the south end, through Odori Station, and continuing all the way to Sapporo Station:

The incredible density of commerce in the immediate neighborhood of the arcade can be seen in this map, which shows only major landmarks, and not the ~200 stores inside the arcade (from http://ext.pimg.tw/admmone/ca7b0bb43003466b4488a952a4ee0e37.jpg):

We see that the arcade is served by 3 subway lines, 2 trolley lines, and approximately 20 hotels.
