The dog run is next to the lot 2 parking, on the south side of Komazawa-dori. Its approximately 1,200 square meters is apportioned into two areas, 800 square meters for dogs of all sizes, and 400 square meters exclusively for small dogs. Benches and drinking fountains are contained within the facilities. There is no charge to use the facilities, no days when the facilities are regularly closed, and no time limit, so use them at your leisure. However, registration to use the facilities is required in advance. The dog run is so popular that it has been featured in various media outlets, and on weekends and holidays there is often a line.
