The strong yen and tumbling South Korean won are making life difficult for people whose income depends on the two currency's exchange rates.
Jyo Jae Woong, a 21-year-old economics student at Senshu University in Tokyo, said he has been working at a fast-food restaurant ever since the won began falling in October.
"I can't afford to pay my tuition," he said, adding that most South Korean students he knows are encountering similar difficulties and many have begun working part time to cover the loss.
