Seijin n o hi or Coming of Age day is held every year on the second Monday of January to celebrate "new adults" for those who have turned 20, or are turning 20 in the current school year gather for Seijin Shiki - the Coming-of-Age ceremony.

It's like graduating childhood and entering adulthood, but more than anything it's like a modern day Kimono fashion show. The girl who became women in this day were absolutely gorgeous in their furisode kimonos. Furisode are kimonos with long sleeves, beautiful color with exquisite pattern, originally worn by unmarried women. But nowadays, no restrict rules, so you can be older and married still wear a furisode. These kinds of a symbol of "Seijin no hi" and a style often worn by younger women - back in Edo period (1600s - late 1800s) Japanese women didn't have wedding rings to show marital status, they have furisode kimonos to show which status they are.
