TOKYO, July 16 (Reuters) - Japan's super-long government

bonds rose on Wednesday, as investors bought back the bonds

after a heavy selloff this week.

The 40-year JGB yield fell 8 basis points to

3.4%. The 30-year JGB yield fell 2.5 bps to

3.135%.

Yields move inversely to prices.

The 30-year bond yield hit a record high in the previous

session amid concerns about the nation's fiscal health ahead of

a closely-monitored upper house election at the end of this

week.

The market weighed the risk of the defeat of the Liberal

Democratic Party and its coalition partner Komeito, as a

potential defeat could empower opposition parties, which are

seeking to cut or abolish the sales tax.

"The market has priced in the defeat of the LDP coalition

and the expansion of Japan's spending," said Takashi Fujiwara,

chief fund manager at Resona Asset Management's fixed income

investment division.

"So from now until the end of the week, investors may start

buying the bonds to cover short positions. The 30-year bond

yield may not rise further from the current level of about

3.1%," he said.

The 20-year JGBs have not been traded yet,

after the yield rose to its highest since November 1999 on

Tuesday.

The 10-year JGB yield rose to as high as

1.595%, and was last flat at 1.585%.

The two-year JGB yield was flat at 0.785% and

the five-year yield rose 1.5 bps to 1.095%.
