Wakamiya Ōdōri Park, Park in Nagoya, Japan

Wakamiya Ōdōri Park is a long, narrow park in Nagoya's Naka Ward, laid out in the median between the two one-way carriageways of Wakamiya Ōdōri, one of the city's 100-metre roads. Much of it lies beneath the elevated viaduct of the Nagoya Expressway Route 2 Higashiyama Line. It is divided into zones such as the Sculpture Plaza and Water Plaza.

The park took shape as part of the 1989 project marking the centenary of Nagoya's municipal status, when the median of Wakamiya Ōdōri was divided into five plazas from Fushimi-dōri to the crossing with Hisaya Ōdōri. The route of the Nagoya Expressway No. 2 Higashiyama Line was later set above the park, so much of it now lies beneath an elevated viaduct. In 1997, after the Hanshin-Awaji earthquake toppled expressway spans, administrative execution cleared homeless dwellings under the road, including the wooden play structure Bōken Toride.

The park's zones were laid out in 1989 for Nagoya's city centenary: a sculpture plaza between Fushimi-dori and Honmachi-dori, the Wakamiya plaza, a water plaza and a flower plaza at the crossing with Hisaya-odori. At the Yabacho intersection, a clock with figures of Oda Nobunaga, Toyotomi Hideyoshi and Tokugawa Ieyasu performs four times daily, at 12, 15, 18 and 20 o'clock, for about five minutes.

The park lies in the median between the two one-way carriageways of Wakamiya Ōdōri, so it is reached on foot from Yabachō, Kamimaezu or Ōsu Kannon subway stations. Much of its length runs beneath the elevated Nagoya Expressway No. 2 Higashiyama Line. Parking lots along the street, such as Horidome-mae and Shirakawa-mae, hold over 600 ordinary cars, some accepting large vehicles and motorcycles.

The park's adventure plaza once held a wooden jungle gym called Bōken Toride, which became a flashpoint in 1997 when city authorities cleared homeless encampments beneath the expressway overpass. The structure was removed and no longer exists. The park now has tennis courts and a skateboarding area instead.
