History
Shiyakusho opened on 1 March 1954 as Okeyamachi after Furumachi, a 9 July 1920 stop on the original third-phase line over the Sakura-machi pass, was abolished when the line was re-graded with a cutting under Route 34. The stop was renamed Kōkaidō-mae in March 1963 after the Nagasaki Public Hall standing across the street. The hall was demolished at the end of March 2015 and the stop was renamed Shiminkaikan on 1 August 2018, then again to Shiyakusho on 4 January 2023 when the new Nagasaki City Hall opened nearby. On 1 July 2020 cross-line transfers became possible here, easing pressure on the previously sole transfer stop at Shinchi-Chūkagai. It is stop numbers 38 and 45 on the Hotarujaya and Sakura-machi Branch Lines.

Notes
The V-shaped junction at the platform threw type-3 cars off the rails on five separate occasions between 2007 and 2020 — including twice within a single week in 2007 — and an over-corrective wear-mitigation tweak to the nose-rail actually triggered the third derailment in 2015.
