I dug around a bunch of catalogs and fan lists trying to pin this down, but I couldn't find a single, definitive record that says when 'tame gari' was first published and who the original credited author is. There are a lot of similarly romanized titles and indie releases that use the same phrase, so it’s easy to hit conflicting entries — some are doujinshi sold at conventions, others are short manga one-shots or self-published zines, and each of those can have different “first” dates depending on whether you count a convention debut or a later print run.
If I had to give practical next steps based on what I found, I’d check the National Diet Library online catalog, WorldCat, and major retailer pages like Amazon Japan and BookWalker for any ISBN listings. Also scan the cover images for kanji/kana so you can search the original Japanese title (that often clears up mixed romanizations). My takeaway is that without a clear ISBN-backed entry, 'tame gari' might refer to multiple works — which is frustrating, but kind of fun to chase down. I’ll admit I love these little metadata hunts; they feel like detective work.
