Celebrated since 1948, it's a public holiday for those who turned/are about to turn 20 (the age of becoming adult was lowered to 18 in 2018, but the age span for Seijin no Hi remains the same) in the timespan 2. April of the previous year to 1. April of the current year.

Of course, hanamachi workers also celebrate. Sometimes the ladies are wearing family heirloom furisode, or furisode owned by their Okiya.

In 2025, the date for Seijin no Hi is 13. January. Here are some pictures I've collected over the years. Enjoy!

Ayano is talking on her phone with someone; most Geiko and many senior Maiko have smartphones today. They are very practical to call taxis and for being able to call an ochaya or okiya. It also enables Maiko and Geiko who are not from Kyoto to easily keep up with friends and family from back home.
