Japanese traditional culture Hina doll part 2

I  have introduced about Hina doll before.

  The 3rd, March was the day of Hina doll.
This is the day for girls. We have a song for this special day.
 
  We eat sushi on this day, I would like to introduce "Temari zushi".
It's special kind of sushi. I think this kind of sushi have not been
introduced in abroad.

  Do you notice the shape of the sushi is round.
This shape comes from the image of "Temari"

  This idea is nice. I do not know who made this kind of sushi first.

  I could buy this at supermarket on 3rd March.
