is a multi-purpose athletic stadium in Numazu, Shizuoka, Japan. It is located in the Ashitaka Regional Park in Numazu City, Shizuoka Prefecture. It is also used as a ball game field. The facility is owned by Shizuoka Prefecture and operated and managed by Nissan Creative Services as a designated administrator.
Opened in 1996. This is the second prefectural athletic field in Shizuoka Prefecture after the Kusanagi Athletic Stadium in Shizuoka Prefecture. Currently, there are three prefectural athletic stadiums in conjunction with Ogasayama Sports Park Stadium (Ecopa Stadium) in Shizuoka Prefecture, which was completed in 2001.
It was the first full-scale athletic field in the eastern part of the prefecture, and until then, sports events in this area had been held at the Koryo Ground with no seats or at Fuji Sports Park Athletic Stadium in Fuji City.
It used to be used as a home stadium by the JATCO Soccer Club and is now home to football club Azul Claro Numazu.
In the J. League, as a rule, lawn seats do not count to the capacity of a stadium, so the number of seats that can be listed as capacity is set to 5,056, which is only in the main stand. The lawn seats are behind the goal. As seen from the main stand, the left side is for the Azul Claro side and the right side is for the away supporters.Since the Ashitaka Park Stadium does not meet the J2 and J1 requirements, the clubs vision is to obtain a J1 license by 2024 and to be promoted to J1 by 2027. In order to expand and renovate the stadium, Ryuji Watanabe, President and CEO of Azul Claro Suruga Corporation, submitted a request to The Mayor of Numazu, Akiho Onuma and the "Shizuoka Eastern Regional Football Stadium Initiative Liaison Committee" was held in 2018 to discuss future development.
