TOKYO, June 6 (Reuters) - Japan's 30-year government

bonds (JGBs) were flat on Friday after being untraded for most

of the session, following a weak auction for bonds with the same

tenor in the previous session.

The 30-year JGB yield was flat at 2.885%.

The bond price rose in the previous session even as the

closely monitored auction witnessed the weakest demand in more

than a year.

The price was underpinned by expectations for a possible cut

in the issuance of new bonds by the finance ministry, while the

poor outcome was within market expectation, strategists said.

"Also, there is a view emerging in the market that foreign

investors have started buying the bonds," said Tomoaki Shishido,

senior rates strategist at Nomura Securities.

"Because top bidders of the 30-year bond auction yesterday

were European brokerages, which is not common."

The auction proved poor demand in so-called super-long

bonds, but separate data showed inflows of foreign money into

Japanese long-term bonds in the latest week following sell-offs

in May.

The 20-year JGB yield fell 2 basis points

(bps) to 2.335%. The 40-year JGB yield fell 1.5

bps to 3.055%.

Yields on shorter-dated bonds climbed, with the two-year JGB

yield rising 1.5 bps to 0.765% and the five-year

yield up 2 bps to 1.025%.
