Tokyo stocks opened 1.23 percent higher on Thursday in line with US and European markets following an Israel-Hamas ceasefire, with share prices also supported by the weakening yen.
The Nikkei 225 index at the Tokyo Stock Exchange was up 113.80 points at 9,336.32 at the start.
The Dow Jones Industrial Average rose 48.38 points (0.38 percent) to 12,836.89.
The yen weakened further in early Thursday morning to 82.54 yen against the dollar from 82.51 yen late Wednesday.
"Most important, of course, is the continued yen weakening," Hiroichi Nishi, general manager of equities at SMBC Nikko Securities, told Dow Jones Newswires.
The euro fetched $1.2859, up from $1.2826, and 106.12 yen from 105.84 yen.
Volume on Wall Street was light ahead of Thursday's US market closures for the Thanksgiving Day holiday. Markets will reopen Friday for a shortened session.
Japanese markets are closed Friday for a holiday.
