TOKYO, Dec 20 (Reuters) - Japan's government is set to reduce scheduled sales of Japanese government bonds (JGBs) by 11.3% to 171 trillion yen ($1.19 trillion) next fiscal year from the current year, according to a draft plan.

Much of the reduction in scheduled JGB sales to the market will be made in shorter-dated debt - one year treasury discount bills, two-year and five-year bonds - amid speculation the Bank of Japan may roll back its negative interest rates policy.
