I couldn’t verify a reliable count for “how many ferries were cancelled in Sept 2025 from Tokyo” from the available information. The search results only show partial or unrelated ferry disruption notices, not a complete Tokyo- specific September 2025 cancellation total.

What is known

  • Tokyo’s island-transport service confirms that ferry schedules can be cancelled due to bad weather, but the page shown does not provide a September 2025 cancellation count.
  • One Tokyo-islands notice mentions changes and cancellations for some large-ship routes, but it refers to 2023, not September 2025.
  • Another result is a route archive page without a cancellation total in the snippet provided.

Best answer

At this point, the safest answer is: the exact number of cancelled ferries in September 2025 from Tokyo is not established by the available sources.

Data gap

To give a precise number, I would need a month-by-month Tokyo ferry disruption log or an official operator archive covering September 2025.
