子供の日
Children's Day（▼May 5）
説明
Children's Day is a national holiday that falls on May 5. It is designated as a day to respect children's individuality and to promote their well-being. As it was originally called Tango no Sekku, or Boys' Day, many families celebrate this day by doing things that honor boys, such as flying koinobori (carp streamers) or displaying warrior dolls. On this day it is also the custom for people to take a bath with iris leaves floating on the surface and to eat kashiwamochi, or rice cakes wrapped with oak leaves.（意訳：国民の祝日の一つで５月５日．子供の幸福をはかり，人格を尊重する日と定められている．もともと端午の節句なので，鯉のぼりを立てたり，武者人形を飾ったり，男の子のためのお祝いをするところが多い．またこの日は菖蒲湯に入ったり，柏餅を食べたりする習慣がある）
