Food comes in smaller packaging

In Japan the packaging is smaller. (They also tend to overwrap things, but that is another blog post.)

The other day I needed just a little bit more cream, I got it, in the cutest pack. 100ml! Beside it in the photo is the usual size we buy cream (200ml) and behind is the largest bottle of milk you can buy (1L).

I can think of several reasons for this:
1. Many people shop daily. 
2. Shoppers often cart their goods home by hand or on a bike.
3. Kitchens are small.

Another reason why dairy products in particular are so small is that Japanese people don't use much of them.
