Rapid services on the Sōbu Line are primarily operated between Tokyo and Chiba, although there are many through services onto the Yokosuka Line as well as some through services operated from the Yokosuka Line via Tokyo terminating at Tsudanuma. During weekday morning peak periods Tokyo-bound trains arrive once every 3.2 minutes; this is reduced to 10 Chiba-bound trains per hour during weekday evening peak periods. At other times there are approximately six trains per hour. There are many through services operated onto other lines.

Commuter rapid trains, operated during weekday peak periods in the mornings and evenings, make fewer stops than normal rapid trains. There are two Zushi-bound trains from Narita in the morning and a single Narita-bound train from Tokyo in the evening.
