The station opened on 14 August 1900 as Sanuki Station, jointly served by Nippon Railway's Tsuchiura Line and the Ryūzaki Railway. Nippon Railway was nationalised in 1906 and the line became part of the Jōban Line in 1909. The Ryūzaki Railway's successor merged into Kantō Railway in 1965, and a new elevated JR station building was completed in March 1985 while Kantō Railway kept a separate building. After privatisation transferred operation to JR East on 1 April 1987, JR renamed its station to Ryūgasakishi on 14 March 2020 at Ryūgasaki City's request and cost (about 410 million yen), though Kantō Railway retained the Sanuki name.

Until the JR renaming, notices posted in the station warned travellers that this was not the nearest station to the Mother Farm theme park, because passengers bound for Sanuki-machi Station on the Uchibō Line in Futtsu, Chiba Prefecture, sometimes came here by mistake.
