I don't have any commentary, just... interesting. Maybe ideologically motivated, but Japan's left hasn't done anything like this in a while afaik.
If there's some context I'm missing here please let me know, I've been out of the loop on Japanese politics for a while now.
I hope the goverment doesn't use this as an excuse to crackdown on "radicals". Which usually means arresting and banning leftist parties and organizations.
