Tokyo---Tokyo stocks opened 0.99 percent lower on Monday with investor sentiment hurt by concern over Greece's possible default and exit from the euro.
The Nikkei 225 index at the Tokyo Stock Exchange fell 201.98 points to 20,205.10 at the start.
Market sentiment was damped as last-ditch talks between Athens and its EU-IMF creditors collapsed on Sunday.
