23 Years After the Nine-Day Fog, One Tape Goes First — TDA to Report Findings at the Oct. 9 Roll Call

As previously reported, the TDA and Wanyo University are two years into a joint re-analysis, begun in September 2026, of roughly 310 magnetic tapes recorded by the observation network during the 2003 Bay Ninefold Fog. Digitization completed this past June made it possible, for the first time, to read second-scale fluctuations beyond the reach of the era's technology — the starting point for the project. At a briefing on the 24th, the TDA announced that, apart from the full 310-reel analysis, it has selected one reel — covering the first few hours after the lockdown began — for early analysis, with findings to be reported to the Nine-Day Fog family association at its regular Oct. 9 roll call.

According to an official, the reel chosen for early analysis captures the hours immediately following the lockdown's start. "Rather than working through the 310 reels evenly, we thought about a way to report in a clean unit, timed to the family association's monthly gathering on the 9th," the official said. Akiko Urato of Wanyo University, previously reported as part of the analysis team, repeated at Thursday's briefing the line she has used before: "Being able to read something and understanding it are two different things. Just because we can read one reel first doesn't let us promise anything yet about what it holds."

What the TDA repeated most at the briefing was a single line: this is not an announcement meant to raise expectations. As previously reported, the 2003-era observation equipment could only produce time-averaged readings, and 23 years on, what any individual fluctuation within the roughly 1,400 hours of nine-day record actually means remains entirely unknown. "Calling it early analysis doesn't guarantee a new lead will emerge," an official said. "A result of finding nothing at all is entirely possible too," urging news outlets to handle the story with care in their headlines.

Kazuko Sakota, 70, whose husband — a 47-year-old warehouse worker at the time — has been missing for 23 years, as previously reported, told this paper after Thursday's announcement: "Whatever comes of it, or whatever doesn't, we've always said — come report to the same place. This time is no different; we'll simply go and listen, as promised." As previously reported in her own words — "procedure and waiting are kept on separate shelves" — the Nine-Day Fog family association is not showing much visible excitement over today's news, either.

As previously reported, the 12 who went missing were five warehouse workers, three anglers, two residents, and two TDA observers. No belongings were ever found beyond two pairs of shoes left neatly at the quayside, and the previously reported "permeation disappearance" provision remains applied in some of the families' cases and deliberately not in others. The cause of the event itself remains one of the largest unresolved cases in the roughly half-century history of the Yuragi.

As previously reported, independent researcher Karin Kokonoe, 52, has set her next book around the Bay Ninefold Fog, with interviews already reaching a 61st subject — Kazuko Sakota herself. Kokonoe's interviews proceed independently of the TDA's analysis project, but in response to Thursday's announcement she told this paper, "Approaching the fog separately, from the data side and from the testimony side, happening to move around the same time — I have no intention, for now, of checking one against the other."

Findings will first go only to the family association's roll call; the timing and scope of any broader public release will be decided afterward. "Telling the family first is the whole of what we've decided," the TDA repeated, saying it will disclose nothing concrete about the analysis before the 9th. This paper plans to cover the Oct. 9 roll call.
