Tokyo stocks opened 0.44 percent higher on Monday following resilient markets in the United States and Europe last week.
The Nikkei 225 index at the Tokyo Stock Exchange rose 39.86 points to 9,202.36.
"There are no signs yet of a pause in the current general risk-on mood, helped by receding fears over the global economic crisis which is benefiting equities," said Hiroichi Nishi, general manager of equities at SMBC Nikko Securities.
The Nikkei was likely to trade in a range of 9,150-9,250 on Monday, he told Dow Jones Newswires.
European stocks ended last week higher while US markets closed it out with solid gains that put the Dow at 13,275.20, its highest level since the last days of 2007.
The euro bought $1.2326 and 98.03 yen in early Asian trade Monday, hardly changed from $1.2330 and 98.10 yen in New York late Friday.
The dollar was changing hands at 79.51 yen against 79.55 yen in US trade.
