Japan resident here. I grew up in the arcade scene in the US. It was the thing to do when we were kids. Sadly, it began to die just as I entered university age. I moved to Japan in my mid 20s and was thrilled to see arcades not only plentiful, but also decently packed.
Before online play was ubiquitous, there was always a line of people to challenge. I loved it! But yeah, the scene is rapidly approaching what I saw back in the US. Even before the pandemic, the scene was dying out. I suppose this is just the nail in the coffin.
On the other hand, I've also lived in South Korea and visit quite often (only a 2 hour flight). The arcade scene is HUGE. It reminds me of its heights back in the US. The places also offer offer a huge variety -- from your typical fighting, MOBA, and crane, to darts, basketball, and target shooting. And oh yeah, little 2 person karaoke booths. It even seems like a popular date spot for young couples. There is also a huge growth in VR arcades and retro arcade bars. The latter is pretty awesome. They'll typically have some retro console/emulators set up, and you pay a flat fee (and a drink minimum) for unlimited play. Can't wait to get back!
