My father had his 60th birthday a few days ago and we celebrated it.
60-year-old is one of the important ages in Japan.
60 means accomplishing one big circle and starting another one in one's life as the traditional 60 year calendar cycle of lunar calendar.
We celebrate with the color of red for 60th birthday.
We used to give a red hood and a red padded sleeveless kimono jacket like this illustration.
We celebrate at ages 70, 77, 80, 88, 90, 99, and 108 too.
Each age respectively carries meaning related to the characters used to express the age or historical facts.
And each age has own celebration color.
