The operation of the buses generally ends between 22:00 and 23:00, but some circular routes and main routes operate until about 23:00, considering that the buses on those routes have been operated as replacements for the former city trams.
大半の系統は22時台に最終便となるものが多いが、循環系統については旧市電代行という側面もあり、一部の主要系統と合わせて23時頃まで運行している。
