My first experience working in shared offices was at co-working spaces in Tokyo, Yokohama, Sendai, and Sapporo. I really liked working at coworking spaces in Japan. Once I came back to US, I tried several coworking spaces including WeWork. None came close to my experience in Japan. I rather work at home in US and at coworking spaces in Japan. Japan coworking spaces are very cost effective, flexible, facilities are top notch (specially internet speed), quiet, and you can be as social as you want or not. There are no gimmicks like beer on tap but some spaces held weekend/after-hour drinking and gaming (poker). I found US coworking spaces to be noisy and interrupting. Most have tenant agreements that run long (UW startup hall took the cake with 24+ pages) and basically ask you to sign your life away to them but they don't take any responsibility for anything.
