In Japan, apparently public demonstrations are allowed.
I was trying to cross the road on my bicycle after Japanese lessons when I heard commotion from the other side of the road. Everyone stopped to look.
The entourage was led by a lady with a loudspeaker, followed by these people with banners and placards.
Amongst them were people with video cameras. I'm sure I got taped. Perhaps that day's evening news captured me photographing them.
Even they have the blessing of the police escort.
How different it is with some countries in South East Asia.
