The four in kimono.

AYAKA updated her Instagram for the first time in the new year, showing her in a kimono with the MCZ members.

These kimono is called "HAREGI (means 'sunny clothes')" in Japan, and is worn for "happy" occasions.

In general, "FURISODE", with its long, hanging sleeves, has a history of being worn by single girls. (Married women usually wear "TOMESODE," a kimono with narrower sleeves.)

The four of them seem to be posing "2022".
