When I was little the arcade market was crazy. There was one in every mall, every shopping center, and even modest sized strip malls had them. Then you'd had random stand-alone ones here and there that were significantly bigger. Every mini-golf place had an attached arcade too. I think I grew up within short driving distance of several. Now there's a couple barcades, one nearby another a longer drive, and none of which anyone under 21 can visit.
Its not a healthy market and nor one that is actually buying video game cabinets. I don't think Ive seen a remotely new cabinet in any of these. Just old classic stuff being kept together with hope, elbow grease, and baling wire. The barcade exprience leaves a lot to be desired as games people like are very old and the maintenance budget and ability of those barcades isn't impressive. The few times I've gone I'd have bad joysticks, bad buttons, machines not registering quarters, hardware locking up, and CRT screens that have aged into displaying burn-in and seemingly a lot dimmer and with more "ghosting" than I remember. They're cost centers to these bars, so they just aren't able to take care of them well, assuming spare parts are accessible (or affordable) for bar economics.
Yes these things won't go away soon, but its a small and shrinking market. SEGA can't justify the rents on those spaces which is a bad sign in otherwise arcade friendly Japan. So the transformation of arcade games into bar toys is almost complete, which is not a healthy sign for this industry. Google says the arcade industry CAGR is projected to be almost 2% during 2021-2025. That's just really terrible and the sign of a stagnated industry and perhaps one entering its negative growth rate period sooner than we might assume.
