Setting: Anywhere from Edo period Japan to the modern day (doesn't matter all that much really)
Are there any milestone birthdays celebrated after the ages of 7 but before middle and old age in Japan? The searches I tried brought up the "7-5-3" Shichi-go-San tradition and mentions of birthdays like 60, 70, and beyond. I'm looking for any special milestone birthday during the teen or pre-teen years. I can fudge the age a bit, so let's say anywhere between 12-15.
