TOKYO, May 1 (Reuters) - Short-term Japanese government bond prices edged slightly down on Monday after the Bank of Japan trimmed its buying in the three- to five-year zone, while the overall mood was languid in thin trading ahead of holidays.
The benchmark 10-year cash JGB was untraded, while 10-year JGB futures ended flat at 151.02.
Tokyo markets will be closed for three days from Wednesday for a string of holidays known as Golden Week. Several markets across Asia and Europe are also shut on Monday for holiday.
The BOJ offered to buy 300 billion yen ($2.69 billion) of JGBs with three to five years left to maturity in its regular buying operations. This is down from 320 billion yen it offered to buy in its previous operation.
The fall was in line with market expectations after the central bank said on Friday that it intends to buy 250 billion yen to 350 billion yen of three- to five-year JGBs at each of its operations for those tenors in May, compared with 300 to 400 billion yen in April and 350 billion yen to 450 billion yen in March.
The five-year JGB yield added half a basis point to minus 0.160 percent, while the two-year yield was flat at minus 0.205 percent. (Reporting by Tokyo markets team)
