Tosu Stadium, Football stadium in Tosu, Japan

Tosu Stadium is a football stadium in Tosu, Japan, designed to host professional matches and other sporting events. The structure features four distinct stands with varying levels of coverage, supported by steel framing throughout, with some corner areas left open.

Built in 1996 on the former Tosu locomotive depot and marshalling yard beside JR Tosu Station, the stadium opened on 16 June 1996 with a JFL match between Tosu Futures and Honda, watched by 20,686. Tosu Futures disbanded in January 1997; the venue later became the home of Sagan Tosu. It was named Best Amenity Stadium from January 2008 to January 2019, when Ekimae Real Estate Holdings of Kurume took over the naming rights.

The stadium's name has changed with its sponsors: Best Amenity Stadium from 2008 to 2019, then Ekimae Real Estate Stadium, nicknamed "Eki-sta", from 1 February 2019. The main and back stand pillars are modelled on a Yayoi-period bronze dagger excavated in Tosu. Since 2005 the Sagan Tosu club office has occupied the ground-floor office space.

The stadium is a three-minute walk from JR Tosu Station via the pedestrian bridge, and about ten minutes by taxi from Nishitetsu Ogōri or Shin-Tosu stations. The main and back stands are fully covered and seat 24,130; the goal-end side stands have no roof, with standing room on the second tier and bench seats on the third. Smoking is only allowed outside the entrance gates.

The main and back stand pillars are modelled on narrow bronze swords excavated from Yayoi-period ruins in Tosu. The corner gaps between the back and side stands are so tight that the uncovered part of the back stand's second tier doubles as a connecting walkway at its top row.
