Masada Soccer Ground, Soccer training ground in Higashi-ku, Japan

Masada Soccer Ground is a soccer training facility in Higashi-ku, Okayama, Japan, with three full-size pitches, two laid with natural grass and one with artificial turf. The south side of the complex has viewing areas where visitors can watch activity on the fields.

Fagiano Okayama trained at three borrowed sites until a supporters' petition gathered 284,673 signatures, submitted to the city on 25 November 2010. Okayama then decided to build on unused land at the Okatō sewage plant, and the artificial pitch opened for training on 23 February 2013, with the official ceremony on 27 March and full opening on 1 April 2013.

Masada Soccer Ground is Fagiano Okayama's training base, not their match stadium. It also hosted home games for Fagiano Okayama Next in the Chugoku Soccer League and for Mitsubishi Motors Mizushima FC, ENEOS Mizushima and NTN Okayama. The club office moved here from the Okayama Chamber of Commerce building.

The ground lies about 15 km from Okayama Station and roughly 7 km from Ōdara Station on the Ako Line. Buses from Okayama Station toward Saidaiji via Okimoto stop at Mitsu, about 3 km away. Viewing is possible only from the stands on the south side, and the grass pitches are reserved for Fagiano Okayama's priority use.

Before this facility opened, Fagiano Okayama had to train at scattered locations around the region, which made managing the team's daily routine much harder. Having one dedicated place changed how the club could plan and run its day-to-day operations.
