Carp streamers are hung in anticipation of "boy's day" or "children's day".
Back home, we have our longest holiday seasons in the autumn (Thanksgiving) and winter (Christmas and New Year's). There are random days off here and there in spring, but no long holidays when everyone gets to take several days off. In Japan, "Golden Week" starts in the last week of April and continues into the first week of May. It's a string of national holidays ending on May 5 with "boy's day" or "children's day". It's one of the best times of the year to take a vacation, and I'm happy to be able to spend this period of time with my husband.
I'll miss having this string of national holidays in the spring to enjoy.
