The racetrack was originally constructed to satisfy the recreational demands of the foreign merchant community in Yokohama.
Architect J.H. Morgan, who designed the grandstands, was also responsible for several other prominent early-Showa period buildings in Yokohama.
The grandstands were constructed using seismic-resistant technology that was considered advanced for Japanese infrastructure in 1929.
Following the 1945 surrender of Japan, the United States occupation forces converted the grandstand interior into residential quarters for military personnel.
The Yokohama City government has frequently debated the tension between preserving the structures as historical heritage and demolishing them due to safety concerns regarding structural decay.
The site remains largely off-limits to the public, requiring visitors to view the architecture from behind the park's perimeter fencing.
Parts of the complex have been utilized as a filming location for Japanese dramas and films, specifically for scenes requiring a decaying, post-apocalyptic, or historic atmosphere.
The Negishi Racetrack Grandstands are the remnants of Japan's first modern horse racing facility, established in 1866. Designed by American architect J.H. Morgan in 1929, the reinforced concrete structure features a distinct modernist style with curved edges and a central observation tower. The facility ceased racing operations in 1942 due to World War II and was subsequently requisitioned by the United States military for use as a housing complex known as 'The Heights.' After returning to Japanese control in 1982, the site was integrated into Negishi Forest Park, though the grandstands themselves remain largely fenced off and derelict. The site currently serves as an architectural monument representing early 20th-century Western influence on Japanese recreational infrastructure. It remains a notable example of 'ruin architecture' within an urban public park setting.

Bring a telephoto lens if you are a photographer, as the main structures are fenced off and require distance to capture properly.
Combine your visit with a walk through the surrounding Negishi Forest Park, which offers well-maintained trails and open green spaces.
Visit on a weekday to avoid the local families and groups that frequent the adjacent public park areas on weekends.
Do not expect to enter the interior of the grandstands; they are permanently closed to the public for safety reasons.
The grandstands themselves are permanently inaccessible to the public, though the surrounding Negishi Forest Park remains open daily.
Do not attempt to climb the perimeter fences or trespass into the restricted zones, as the site is structurally unsound and heavily monitored.
