Tokyo's benchmark stock index rallied on Friday, after China's debt-laden Evergrande Group said it would be able to meet a key repayment deadline.
The Nikkei Average ended the day at 30,248, up 609 points or 2 percent from Wednesday's close. Thursday was a holiday in Japan.
The index suffered big losses earlier in the week on fears that financial problems at China's second-largest property developer could have major knock-on effects.
Evergrande has outstanding debts of more than 300 billion dollars and is considered to be at risk of defaulting.
The company faces more repayment deadlines in the weeks ahead, and will continue to be a subject of close scrutiny by investors.
