"Kissa" (喫茶) in Japanese means tea-sipping, and sometimes it's pronounced "kiccha". Jazz Kissas today would be places to be under influence of alcohol or caffeine and concentrate on listening to jazz, but kind of often in 60s also under influence of non-legal stuff.
It's kind of interesting that we Japanese received what was originally a dance music and allocated it to our custom/culture to sit and listen like to a preaching. I guess people might had felt some kind of awe or something from it those days.
