JR confirms Uchibo Line service from Kisarazu to Awa-Kamogawa will resume with the first trains September 26
At 21:00 on September 25, JR changed its outlook to a restart announcement. Suspension between Anegasaki and Kisarazu and reduced service north of Anegasaki remain separate.

At 21:00 on September 25, JR East announced that Uchibo Line service between Kisarazu and Awa-Kamogawa will resume with the first trains on September 26. Earlier notices had described reopening as an expectation.
Anegasaki–Kisarazu remains suspended
The restart covers the section south of Kisarazu. Recovery between Anegasaki and Kisarazu is still expected to take at least about three months. Replacement buses from September 28 onward remain under consideration, with frequency and boarding points not yet announced.
Chiba–Anegasaki is running about 30% of normal service during morning and evening periods. Both directions of the September 26 B.B.BASE Tateyama service are cancelled throughout. This announcement does not mean normal service across the entire Uchibo Line.
This follows the September 23 recovery outlook. Check current transport information and JR East before departure.
