Two people have died in Japan and several are in a critical condition after choking on traditional rice cakes as part of the new year celebrations.
They may seem harmless, but each year the hard-to-eat snack claims several lives, prompting annual warnings from officials.
What is a mochi?
The cakes, known as mochi, are cute round buns made of soft and chewy rice.
The rice is first steamed and then pounded and mashed.
What's a safe way to eat them?
Chew, chew, chew. If that's not possible, the rice cakes need to be cut into smaller pieces.
Each year, authorities issue public warnings in the run-up to the new year festivities advising that people - especially the very young and elderly - should only eat mochi cut down to smaller little chunks.
Yet despite the warnings, each year there continue to be deaths linked to the dish.
At the turn of 2014 to 2015, the number of casualties peaked at nine. In 2016 it was one, while last year two people died.
Each year, many more end up in critical condition in hospitals across the country, reports BBC.
