The No. 3 Appraisal Center released part of the scientific data on the Fukagawa drift container opened on September 29, including close-up images of the markings on its inner surface and isotope-ratio measurements. The possible link to the markings on the tentatively registered Lineage 148 metal post, and the cause of the liquid surface's failure to follow the container's tilt, both remain unexplained.

On the 2nd, the No. 3 Appraisal Center released, as promised, part of the scientific data on the Fukagawa drift container opened on September 29, as previously reported. The release included magnified images of the markings on the container's inner surface and isotope-ratio measurements for both the liquid and the container itself. On the markings, the center reaffirmed its earlier finding that they share "something in the way the lines are drawn" with the symbols on the tentatively registered Lineage 148 metal post, but maintained its cautious stance that "a resemblance in shape is as far as we can say."

The new data offered no explanation for why the liquid's surface fails to follow the container's tilt. The two remaining containers, still held in storage, are unrelated to this opening; a full academic paper is expected to follow at a later academic presentation. The center commented, "This release has done more to sharpen the outline of what we don't know than to answer anything."

    Fukagawa Drift Container Opened — the Liquid Inside Remains 'Unidentified'

    The Third Appraisal Center on the 29th opened one of the three metal containers that washed ashore in Fukagawa 2-chome before dawn on Aug. 21, inside a sealed chamber. As previously reported, the liquid inside behaves like water and its isotope ratio matches no known lineage — the opening did nothing to explain why the liquid's surface fails to track the container's tilt. One new observation did surface: engraving on the container's inner surface bears a 'similar shape' to the symbols on the metal post from the separately reported provisional Lineage 148, though the center stopped short of asserting any connection. Attendance was limited to review-board members, Fukagawa neighborhood-association representatives, and center staff, with no media access.

    Window 5 Voice Recording Partly Released — 'It Sounds a Little Like the Shore Lullaby,' Says Ushio Kishiura

    The TDA's Dimensional Survey Division released part of the raw, pre-analysis recording of the 'voice-like sound' captured before dawn on September 30 at Window 5, 'the Sword Country,' to reporters on the 2nd. Ushio Kishiura, 74, who transcribed 'the Shore Lullaby,' said after listening that it 'sounds a little like the lullaby's phrasing,' though she stopped short of any firm claim. The division maintains there is nothing to confirm it as a human voice.
