Roppongi reminder

Why is Roppongi singled out ? I am often there and don't see many people drinking on the street where as Shibuya has many people doing that.

Yes, and drunks reads and heeds these signs when intoxicated.

Hmmm. I know that place. That sign is right nearby where I would I sometimes have a can (with famichiki). Somehow I think bar owners are behind this.

みんなで守る、まちのルール

Are these legal rules or mere 'manners?'

What powers do those requesting 'compliance' have?

It's just your chounaikai, crusty jiji group trying to browbeat residents into compliance with a vaguely worded declaration that tricks people into thinking it's actual law

I wonder why people are against a group of people just trying to get others to keep their streets clean.

I really don't see any harm in this. Although I agree the Japanese tend to use the word ルールfor laws and ordinances as well mannerly conduct creating some confusion.

Why is the garbage collection system so crippled down?

Put some garbage cans on the streets like every other first world country.

This "rule" is probably promoted by bar operators.

No outside drinking. No cheap bevvies from vending machines or convenience stores. You must come in and pay our prices.
