As many of you know, the oldest JTK1 instance we currently have dates to July 24, 2005 where it was posted on Fileman by an anonymous user. For years, this has been our oldest instance and we've been unable to find anything earlier.. until now.

On October 17, 2026, investigator 'A Refined Gentleman' created a Futaba post requesting any information about the original image. Most users in the thread either posted mockups or unrelated material, however, one reply to the thread caught our attention.

An anonymous user posted a JTK1 instance, along with a claimed timestamp of June 13, 2005 at 21:43:32. Whilst vague, we can imply that the timestamp is referring to when the JTK1 image the user uploaded was created. We were initially sceptical of the legitimacy of the image as it was posted with no other context. That was until, in another thread, the same user sent another image.

The user posted a screenshot of the metadata of the JTK1 instance from his computer, showing us it was created on April 28, 2015 (likely meaning that the user saved this image to their computer on this date / moved the image to a new hard drive on this date) and a modified date of June 13, 2005 at 21:43:32 (matching his previous timestamped comment). We were also given the original filename, "1118665447103.jpg", however searches for this filename on 5channel and other archives have yielded no results. This filename also matches the timestamped comment.

A few weeks later on November 7, 2026, A Refined Gentleman revisited the instance, and with the help from AI, realised that the bytes of the file were the same as the bytes in the aforementioned computer screenshot. Performing a preliminary check, he realised that compressing the JTK1 image matched the gazo-box instance, although we were uncertain as to where and how it was compressed. That was until another investigator - PerditusRedux - remembered his and UotasSoft's research into the Fileman instance the year prior. He (PerditusRedux) decided to use the "-convert" command on an older version of ImageMagick (the software used for Fileman's image compression during 2005) on the new instance, which revealed a byte-for-byte identical file output that matched the gazo-box instance (our prior investigation has proven that the latter matches the Fileman instance). By also using the "-convert 100x100" command on the new instance, this also resulted in a byte-for-byte identical file output of the JTK1 Fileman thumbnail. To put it simply, the JTK1 instance posted to the thread by the user is most likely legitimate and likely dates to June 13, 2005.

This discovery is huge and completely changes how we view the search. It also likely verifies Miyama's initial testimony from 2021 where he states JTK1 was being spread during the June / July 2005 period, which he said before the July 2005 Fileman instance was found. This makes Miyama one of our most reliable witnesses yet. Additionally, this could confirm that JTK1 did indeed originate from Futaba, something most of the investigators have theorised for years; It is also potential evidence towards another hypothesis: that the original image (JTK0) likely still exists, albeit on an offline or obscure log warehouse.

While our analysis has proven this to be a likely new instance, we are unable to confirm the exact origins of the user's image, meaning this discovery is not currently definitively confirmed.
