Japanese family share this rice cake together in “a fine day” in hope of one-year happiness, and eat. It is Japanese faith and culture to receive a blessing from God. In other words a rounded rice cake offered to god and after that, people can have it.
Why do people start to call “ kagami kochi, mirror rice cake” ? One of reason is that the rounded rice cake is a similar shape as ancient mirror. from old time, people believe the god reside in the mirror.
Reflecting on ourself in Japanese is “ kangamiru”. The sound had slightly changed and in the end, people called it “ kagami” . So, the mirror in Japanese is “kagami”.
It’s not clear as the origin of the round rice cake. In Genroku period (1688-1704), the old picture shows that pile of the both rounded and diced rice cakes. So this is the oldest of the round rice cake in the history.
The act feeling to thank for having been safe for one year is very peculiar Japanese culture with the history.
