These Japan '83 shows are notorious for having caused so much confusion about the exact datings, but since 2012 there is some consensus on the dates, as given by u2gigs:
1983-11-22 - Osaka, Japan - Festival Hall
1983-11-23 - Seto City, Japan - Seto-shi Bunka Center
1983-11-26 - Tokyo, Japan - Shibuya Kokaido
1983-11-27 - Tokyo, Japan - Shibuya Kokaido
1983-11-29 - Tokyo, Japan - Shinjuku Koseinenkin Kaikan
1983-11-30 - Tokyo, Japan - Nakano Sun Plaza
At least it must be noted that files contained in the 1983-11-29 u2-start file do not match the setlist as given by u2start. The set is supposed to have "A Celebration" since this was mentioned explicitly by Bono in the last Japan '83 show, but the mp3 audio-files do not contain "A Celebration."
Instead, the offered audio-files seem to belong to "1983-11-23 - Seto City, Seto-shi Bunka Center," as will be consistent with the given setlist for that date (u2gigs). See also Dana Fletcher's comment 49988 on u2torrents and Pimm Jal De La Parra, A Concert Documentry (errata).
I hope this comment is helpful and that u2start will relocate the mp3 audio file to 1983-11-23 Seto City.
Thus far I haven't been able to locate the proper concert recording for
