The Sapporo Ekimae-dori Underground Pedestrian Space also known as Chikaho, opened on March 12, 2011. The underground walkway runs for 520 meters and is a huge space.  This walkway has a few restaurants along its path, a couple of coffee shops, art & event spaces. There are two toilet facilities and numerous rest stops and places to sit down. The underground walkway is particularly useful and popular during the cold winter months. This in turn connects with other underground shopping areas, so you can easily access most of downtown Sapporo without walking through the winter snow and cold. 

The walkway has many spaces that can be rented out for use, so throughout the year there is always something going on in the tunnel. To rent out a space, then you can contact them directly via their website. There are four spaces that are available to rent. The cheapest which is 24 square meters costs ¥7200 per weekday and ¥20,000 per weekend. The largest space is 300 square meters and that costs ¥150,000 per weekday, and ¥360,000 for the weekend. With the amount of people walking by, its a great way to exhibit or promote an event! The walkway connect to Pole Town which continues all the way Susukino subway station. The other walk way, called Aurora Town, branches off to the east leads to the TV Tower and clock tower
