September2026 service restrictions on Chiba's Uchibo Line after Typhoon25, replacement buses between Anegasaki and Kisarazu, and ticket refunds. Distinguish effective dates from updates.
JR East said on September 29 that it was still trying to secure buses for the suspended Anegasaki–Kisarazu section. Its rail notice gives no substitute-bus start date, timetable or capacity; extra highway buses listed by another operator serve different routes.
JR East’s notice dated September 28, 2026 says travellers who abandon a trip because of Typhoon 25 disruption can obtain a no-fee refund for an unused ticket that starts, ends or passes through the suspended Anegasaki–Kisarazu section of the Uchibo Line. The notice applies to travel dated September 28, directs station purchases to a JR counter and sends agency products back to the seller. Already-used tickets require advice from station staff.
Kominato’s additional Tokyo-bound vehicles do not guarantee a seat. Its highway-bus rules distinguish available capacity, baggage storage and group travel from the published departure schedule.
JR East’s Chiba–Anegasaki timetable takes effect from September 25, while the onward section to Kisarazu remains suspended in its latest checked notice. The document’s boundaries and the operator’s overnight information pause matter when interpreting travel options.
