Women wearing kimonos are seen outside of Yokohama Arena on January 09, 2023 in Yokohama, Japan. For about 140 years, the age of adulthood in Japan was 20 years-old, but in April 2022, it was lowered to 18. Some activities, such as smoking and drinking are still not permitted for people under the age of 20. Many cities continue to have ceremonies for citizens turning 20. However, they are changing the name of the ceremony to “20 years-old gathering”. (Photo by Takashi Aoyama/Getty Images)
