Here, there's no need for roosters.

They have all been replaced my mechanical ones that shout advertisements at you first thing in the morning.



Heads up, this isn't my video.  I can never get myself dressed fast enough to fly down 4 flights of stairs so that I can catch one of these suckers before they get out of my keitai's microphone range.  Though who am I kidding, that mic hears only me anyway.

So why first thing in the morning?  Why do this to you at the crack of dawn?

Because it's a garbage truck.  Naturally.

Remember, sorting and disposal of trash here in Tokyo is a big deal.  We have people coming nearly every day of the week to pick up something.
Mondays - burnables.
Wednesdays - paper and プラ(recyclable plastics (almost everything here is プラ)).
Thursday - burnables again.
Friday - non burnables, like batteries, metal, glass, porcelain shards.
Saturday - cans, glass and pet bottles.
You'd tend to think that means that you'd have everything covered.  However, disposal of anything that's larger than a breadbox requires someone to come and pick it up.  That's where these guys come in.

Every morning, somebody in the neighborhood needs to have a truck come out to take their oversized garbage away.  The city doesn't provide you with the service either.  Sure, they'll hook you up with somebody, but it's an independent group who charges you for their labor.  Since it's a business with some competition, you start seeing each contractor trying to reach out to the people in the neighborhood.
By waking them up with a loudspeaker mounted to a truck that stalks at 10 kilometers an hour down your road.  All throughout the day, every day, without fail.

However, like with birds, you learn to tune them out too.
