Ryuji Utomo Prabowo (born 1 July 1995) is an Indonesian professional footballer who plays for Liga 1 club Persita Tangerang, on loan from Bali United.

As an apprentice to Arema's more senior players, Ryuji began to build his reputation as a physically robust defender who caught the attention of richer clubs at the end of the ISC.

During a pre-season tournament ahead of the launching of the new Liga 1 (Indonesia) top-flight competition, Ryuji left Arema after failing to win a starting position.

Ryuji played in nine matches for Persija in the 2017 Liga 1 season, impressing coach Stefano Cugurra who used him when senior players were on international duty.

Without certainty on when professional football in Indonesia could resume, Ryuji chose to take an offer to play for the newly promoted Malaysia Super League club Penang for one full season.

At Rayong, Ryuji developed into a more versatile player as coach Teerasak Po-on often played the center back as a defensive midfielder.
