扇子
“sensu”
A sensu, a folding fan made of bamboo ribs covered with Japanese paper, is fan-shaped when opened and like a bamboo stick closed. It is said that the uchiwa (round fan) brought from China was remodeled into the sensu by Japanese and that the folding style was reintroduced to China and brought all the way to Europe. There is a phrase, “hidari uchiwa de kurasu.” Hidari means left and kurasu means live. So like using an uchiwa with your left hand, this phrase means “living in comfort” or “lead an easy life.” You can say this expression to someone who won a lottery.
