With 72,327 seats, the stadium has the largest spectator capacity in Japan. All the seats are individually sectioned with 90cm of space between rows, so spectators can sit back and enjoy the games in comfort. To ensure that spectators do not miss any of the drama, large screens are installed on both Side Stands for instant replays of outstanding plays and scores. Additionally, the sound coming from the 528 loudspeakers adds emotion and excitement to the game. Three quarters of the seating area is covered by a large roof. | ||||||

Ideal playing conditions
Our greatest pride is of course, the natural grass. The groundskeepers work hard throughout the year to keep the grass in top condition for playing and take extreme care in planting summer and winter grasses. Other characteristics of the stadium include the positioning of the lights placed to avoid the formation of shadows of the players and the reduced wind effect, thanks to the roof that covers three quarters of the spectator seats. | ||||||||

Ideal news reporting facilities
There are coaxial and optical fiber cables installed among the broadcast rooms, the relay van parking and the parabolic antenna site in order to make any radio or TV broadcasts possible without the need for wiring the facilities. The 288 seats for press are protected from the rain by a movable roof, and it is possible to send and receive data by connecting faxes and computers to the jacks provided. Additionally, and responding to the demands of the press companies, we have been improving the information infrastructure to make it even easier and more practical to use. | ||||||

There are 147 permanent seats for wheelchairs. If necessary, it is possible to have as many as 632 wheelchair places using seats designed specially for this purpose. Water for flushing the toilets and other facilities is a combination of rainwater collected from the roof and treated and recycled waste water. The roof and the walls are fitted up with sound-absorbing panels and all the lights are placed under the roof so as to avoid the emission of light to the outside. | ||||||
