Mochi-tsuki - Rice Cake Making

We can see that everywhere on that season, in front of shop, on the shopping streets, in the local living area, and so on.
I could that at shop-front of MARUI shopping centre where located in front of the Totsuka JR station,
3 persons was working together to some mount of steamed rice in a mallet mortar. 1 person was kneading and upsetting that and 2 people was pounding that in rotation. I though about it so regular working.
Many people, including me, was watching their working, and was waiting the mochi, rice cake, was completed.
Because we could eat fresh rice cake there.
That is Mochi-tsuki, Japanese popular custom on the New Year season.
