Like most big cities (Osaka, Tokyo Yaesu, Fukuoka TienJin) there will be larger underground area for both pedestrian movement & also retail space. The one in Sapporo is considered a larger one approximately 520m, stretching from Sapporo Station to Odori Station on Subway Namboku Line. Both stays for us in Sapporo are close to it so we use quite often. There are throngs of people moving through the place daily, including tourists like us. Reckon it would be a great place against inclement weather (rain/winter) while at same time can enjoy both shopping & dining; plenty of Shops, restaurants & more. Noted there are some recess area whereby Events activities are setup along the long walkway, definitely a great way for exhibition or promotion. We have seen children art drawing, weekend local veg sales and even Sports promotion over our past trips here. There are tables and chairs for one to relax, and there is also a free Wi-Fi service. I saw on documentary there had even placed a piano for passerby to play Impromptu too!. We especially like to explore from Akrenga Terrace onwards, going down to get bf at either Pronto or Mac. Noted that the walkway connect to Pole Town and continues all the way Susukino subway station. The Aurora Town branches off to the east leads to the TV Tower and clock tower. Sure fun for exploring. A must-visit, do include inside your itinerary in your next trip here at Sapporo. When it rains or weather too hot/cold, this underground is just wonderful!

The underground maze of several walkways going back and forth seem to stretch several kilometers. The weather is indeed chilly during winter , and staying at the Sapporo Grand Hotel , we would later discover this pathway underneath at the basement which has a plethora of shops , restaurants and fast food outlets. Several toilets along the way can be seen. But take note most are closing by 9 pm so we can be wary of that .

Sapporo's colossal network of underground streets is like stepping into a city beneath the city. Here, there are cafes and restaurants, shops and toilets - and a delightful calm, even when there are many people. We ended up having both breakfast and lunch at two of the restaurants, and it simply doesn't get more authentic Japanese than this. One of Sapporo's major attractions!

We found the sidewalks were not always well maintained and could be icy/slippery when we visited Sapporo in December so the underground areas were very appreciated to help traverse the city. The underground connects areas like Sapporo Station and Odori Park and we were surprised how far some of the passageways reached out. We had a few convenient entrances near our hotel and once we figured it out we did not have to go outside to go to/from the main train station - We wish we knew this earlier!
