Sushi or Sashimi is always on sale at any department stores' food floor. Especially on such special holidays like New Years Day, those bento boxes are sold well because many people take rest at home and eat at home rather than dinig out.
I also bought a lot of bento boxes for New Year Holidays and enjoyed small family party. Sushi is beautifully displayed and at this occassion, we often see a party plates ( like photo below). It's packed with various food for party time.
Autually seafood is more popular than meat in Japan as far as watching the bento boxes. What I miss most when I go abroad is the real fresh seafood. Japan is surrounded by ocean with small land space. It's natural for us to have seafood in this situation. Also eating meat was prohibited for a long time up unitl about 100 years ago. We grow with seafood.
Hi! I've started my own blog on Japanese culture, so I'm looking at other blogs too. It's interesting to see other people's views! I think bentos are delicious but unfortunately I am allergic to fish!
Please visit here sometimes. I will try to see your blog,too.
