There were already JLF clones in some PS1 and Sega Saturn Sticks. (Hori “Real Arcade PS / VF” variants) the PS1 ASCII Sticks too, although optical, were based on JLF Design (Ascii Zero 3, Justice, and Ascii stick 3).
oldest example I could find was the Spital Sangyo Stick that had an actual Sanwa JLF in it. Which was released during the original PS1 era.

Sega’s versus city cabs that debuted during the “VF boom” in Japan back in the mid 90’s was also the major introduction to the JLF. Sanwa made the versus city panels, which came equipped with JLF’s. arguable, VF cabs made JLF’s popular. Hence HORI’s own “Real Arcade VF” saturn stick had a very similar JLF clone.
JLF isn’t as young as you’d think. The reason why it’s so “new” I assume is because of several things. They became the “standard” because several key arcade cabinets stocked them. The Sega Net City/New Net City then the Sega Lindbergh, Namco NOIR’s , and the game changer, Taito’s Vewlix. And the debut of Hori’s own HRAP series, which came equipped with JLF’s mostly. It’s funny though, look up archives of japanese blogs from 2005-2009, most are about modding HRAP’s into LS-32’s. haha.
here’s a Sega Versus City scan from a a catalog flyer
Looks like a JLF. Versus City cabs were made in 1996.
while we’re at it.
Early on, LS-32 were the standard in NeoGeo cabinets (MVS, Neo 25/50’s/29, SCU’s) up until NeoCandy where it suddenly switched to LS-40’s (even still most flyer scans i see only has LS-40’s in “Super Neo Candy’s”). even more proof is if you watch most of SNK game’s “How to play” Screens, you can clearly see that LS-32’s and PS-14-G’s are being visualized. Arguably though, the NeoCandy line of cabs were the most popular from SNK (due to it having an actual 2L14B button layout, suitable for non 4-button neogeo games, and jamma wiring).
the alleged seimitsu NeoGeo AES stick too has more similarities with LS-56, not LS-40. the same ls-56 mounting plates and restriction gates can be used. haha.
according to this japanese arcade stick wiki , the LS-40 were historically found in Taito Egret II, Namco Excelleena and SNK Neo29’s. heh. LS-56’s were in sega naomi cabs. But earlier there were also the Sega Virtua Sticks/ and Konami HyperStick that used them.
