Tokyo stocks opened 0.81 percent higher on Monday, buoyed by a weaker yen and gains in US and overseas stock markets last week.
The benchmark Nikkei 225 index was up 122.49 points at 15,260.61 at the start.
"Bullish equities markets and the progressively weaker yen should help drive the market to a fresh multi-year high after much profit-taking in the last several sessions," said Hiroichi Nishi, general manager of equities at SMBC Nikko Securities.
US stocks closed another week of record highs Friday as investors focused on the positive side of mixed economic news and corporate earnings.
The Dow Jones Industrial Average jumped 0.80 percent to 15,354.40 while the the broad-based S&P 500 rose 0.95 percent to 1,666.12.
The dollar was changing hands at 102.73 yen in early Asian trade Monday, down from 103.19 yen in New York late Friday but still up from the lower 102-yen range seen before the Tokyo market closed on Friday.
The euro was quoted at $1.2826 and 131.80 yen against $1.2834 and 132.44 yen in US trade.
