The Nikkei stock index climbed 1.72 percent to a one-month closing high Tuesday as investor jitters over Greek opposition party Syriza's victory in a weekend general election and the likelihood of new anti-austerity measures to be implemented by the party settled.
The Nikkei 225 added 299.78 points to end at 17,768.30, while the broader Topix index of all first-section shares gained 1.73 percent, or 24.30 points, to finish at 1,426.38.
Local traders here noted that despite shears in Athens falling on Monday after the election, other European bourses extended winning streaks, as concerns have eased about the likely anti- austerity policies the new Syriza party will introduce to Greece.
