About the Shinjuku City Half Marathon
The National Stadium is the anchor here, serving as both the main venue and the finish for a certified urban half through Shinjuku. The event uses a firm sequence of checkpoints and can briefly stop runners for pedestrian or vehicle crossings, so it rewards even pacing more than an all-out opening through the city streets.
Course
The certified course starts and finishes at MUFG Stadium, Japan's National Stadium, and runs through Meiji Jingu Gaien, the east side of Shinjuku Station, and Kagurazaka. The 2:30 limit includes multiple intermediate checkpoints. Traffic operations may require runners to slow or stop at crossings.
Race-day weather
Tokyo's 1991-2020 January normals average 5.4°C, with a 9.8°C average high and 1.2°C average low. The 8:30 a.m. start therefore calls for cold-weather layers, but runners should use the event forecast for wind and precipitation decisions.
