team Nadeshiko.

Someone call them Samurai sisters. But they are called "Nadeshiko Japan."

So,they are Japan's women soccer team.
When the representative team was called,this nickname was given. It came from Japanese term "Yamato Nadeshiko",personification of an idealized Japanese women.
Yamato is an ancient name for Japan and Nadeshiko is a Japanese name of dianthus.
It is a word for describing modest and neatness woman. It is kind of old word though.

The team has been great on this World Cup. It is like we are dreaming but it is true. It might be controversial but they watch the disaster video of 311(March 11) before the game then made sure that they fought for the people in Japan who suffer and struggle from those sircumstances.

Now,they are going to face the Queens on Sunday (Monday 3am on Japanese time.)
