Yamato Sports Center Stadium, Multi-purpose stadium in Yamato, Japan

Yamato Sports Center Stadium is an athletics stadium in Yamato, Kanagawa, with an eight-lane 400-metre urethane track and a 98 by 65 metre field. Its main stand holds 2,000 fixed seats, while the rest of the 2,952 capacity is grass seating. A 50-metre rain-training straight runs beneath the main stand.

The stadium was completed in March 1990, just before the Yamato Sports Center opened in April 1990. It was later certified as a Japan Association of Athletics Federations third-class track venue, but that certification was withdrawn as the track deteriorated. In 2016 it took the name Yamato Nadeshiko Stadium, and from April 1, 2026, it is called Yamato Nadeshiko Sanki Stadium after Sanki Industrial acquired naming rights.

The stadium hosts the start and finish of the Yamato City Ekiden relay race and has twice held the summer travelling radio calisthenics event, on 22 August 2009 and 21 August 2019. It is the home ground of the women's football club Yamato Sylphide, and its cafeteria Minamikaze, near the corner of the main stand, lets spectators eat and drink while watching matches.

The stadium is a five-minute walk from Yamato Station, served by the Odakyu Enoshima Line and the Sotetsu Main Line. The ground lies across the road from the Odakyu line, so passing trains are clearly heard during events. The main stand holds about 2,000 fixed seats, with grass seating elsewhere.

The stadium doubles as a temporary heliport in emergencies and medical evacuations. It sits directly across a road from the Odakyu Enoshima Line, so passing trains are clearly audible during events. The main stand also hides a 50 m rain-training runway beneath the seats.
