History
The station opened on 14 August 1900 as Sanuki Station, simultaneously serving Nippon Railway's Tsuchiura Line and the Ryūzaki Railway. Nippon Railway was nationalised in 1906, and the line was reorganised as the Jōban Line in 1909. In 1944 the Ryūzaki Railway portion was transferred to Kashima Sangū Railway, which became Kantō Railway in 1965. The current overhead JR station building dates from 10 March 1985, and JR East inherited the JR portion at the 1987 privatisation. On 14 March 2020 the JR station was renamed Ryūgasakishi at the request of and at the expense (¥410 million) of Ryūgasaki City, while the Kantō Railway side retains the original Sanuki name.

Notes
When the JR side was renamed Ryūgasakishi in 2020, the Kantō Railway operator declined the change, so the two operators at the same junction now use different station names.
