How so? I’m genuinely curious as a current Tokyo resident.

The main issues Vancouver seems to face are:

Affordability and Housing Crisis: Tokyo is a remarkably affordable city given its status. There’s housing stock at pretty much every price level.

Homelessness and Street Disorder: not a problem in Tokyo

Drug Addiction and Overdose Crisis: not a problem in Tokyo

Traffic Congestion and Transportation: public transportation is stellar in Tokyo. Traffic can get pretty crazy at rush hour, but I hear that’s been the case for a long time and it’s not much of a problem if you use the aforementioned fantastic train system.

FWIW, I left San Francisco after close to 15 years due to the issues above. Tokyo has its problems, but they don’t seem to be in the same category.
