The most popular high end icecream here is Haagen Dazs. The little cups are about 250 yen from convenience stores, but most icecreams are priced at 100-150 yen, and that is what most people are willing to pay.

As above, a lot of people would eat icecream almost every day in summer here because it's so hot. Others perhaps just on weekends.

People like both creamier icecreams and lighter ones- there is a huge range available here, with new versions/products constantly being introduced- it would be a very competitive market.

Oh, and I've never seen Ben and Jerry's in the 12 years I've lived here.
