Of course, Japan has its extremists too, and also many people express more extreme opinions online where they have the safety of anonymity.

But in daily in-person life, you just don't see the extreme politics that you see in the US. Nor do you see it in the regular news outlets. The only really obvious political stuff you see here in-person is the annoying sound trucks blaring far-right political messages. But I haven't heard one of those in quite a while; maybe I'm in the wrong place.
