“Seijinshiki” – Coming of Age Ceremony
On the second week of Monday of January, Seiji no hi, or coming-of-age ceremony, a national holiday is held. Japanese who are coming of age this year will attend ceremonies held throughout the country.
It started since 13th century, and in 1950, the same hometown people get together in a designated place and celebrate. It is rare worldwide. Japanese women ordinarily celebrate by wearing furisode, which is a traditional formal kimono with an elegant long-sleeved Kimoo for unmarried. To wear a black kimono and a hakama, or formal traditional Japanese menswear for Japanese men became the trend.
On the day, you can see so many Japanese wearing Kimono or Hakama throughout Japan. In that sense, you cannot miss the day.
Traditionally, government officials and other distinguished guests give speeches at the ceremony. It is ok to miss them.
