TOKYO, Sept 29 (Reuters) - Japanese government bond prices edged higher on Tuesday after a two-year debt sale attracted ample demand and as some investors turned cautious ahead of the first U.S. presidential debate.
Republican President Donald Trump and Democrat Joe Biden will square off in the debate later in the day, which could help determine the fate of the presidential election on Nov. 3.
Bond prices were also supported after an auction of two-year government debt was met with healthy demand.
