Many large stations in Japan have underground roads extending in all directions, especially at Sapporo Station. Because of the special geographical location, especially in winter, the roads are often covered with heavy snow and the ground is slippery, so many times pedestrians go underground, which is warm without waiting for traffic lights. Exit 2 of the underground passage leads to the Hokkaido Old Road Office, Exit 9 leads to the Clock Tower, and Exit 13 leads directly to Odori Park.
The underground area of Sapporo Station connected to the subway is very large. There are many shops and some interesting furnishings. It can be said to be intricate, and I still don't know the location after several visits.
I personally suggest that tourists go to the underground trail to stroll around. There are all kinds of snacks and a dazzling array of goods. The lively and endless crowds can rest anywhere when they are tired, and they can eat anywhere when they are hungry. It snows outside. It’s even more comfortable to walk through the trails. The subway is easy to transfer. If you buy something you like, you must remember the location. If you want to buy it, it is really not easy to find.
The hall below the metro station is simple and gorgeous, and it's interesting.
The bustling area of Sapporo is the area from Sapporo Station to Susukino Station. How do you walk around this section? If the weather is fine, you might as well enjoy the blue sky and white clouds of Sapporo while walking outdoors. If there is heavy snow in the winter, it is the wisest choice to make use of the underground pedestrian space and underground pedestrian street. The underground pedestrian street in front of the station starts at Sapporo Station and ends at Susukino Station. It takes about 25 minutes on foot (Sapporo-Odori about 15 minutes, Odori-Susukino about 10 minutes). The pedestrian space is not just a communication channel, it is a bustling street in itself.
