TOKYO, Nov 24 (Reuters) - Japanese government bond (JGB) yields were on track for a second session of increases on Friday on an uptick in euro zone and U.S. yields, after hitting multi-month lows earlier in the week.

The 10-year JGB yield rose 4 basis points (bps) to 0.765%, buoyed by a rise in European government yields overnight.

With Japanese markets closed on Thursday due to a holiday, Friday was the first chance JGB investors had to react to a rebound in U.S. Treasury yields overnight on Wednesday.

U.S. markets were closed on Thursday for Thanksgiving.

On the superlong end, the 20-year JGB yield rose 3.5 bps to 1.485%.

The 30-year JGB yield was up 3 bps, climbing back up to 1.675%.

Japanese yields sunk to multi-month lows earlier in the week, with the 10-year yield dropping to as low as 0.69%, but received support after the Bank of Japan (BOJ) cut purchase amounts of some bonds at its regular buying operations on Wednesday.

Caution over more reductions to the BOJ's regular purchase amounts going forward, as well as continued expectations that the central bank will normalise its monetary policy, should prevent any further declines in JGB yields, according to Ryutaro Kimura, fixed income strategist at AXA Investment Managers.

However, "a gradual increase in the preference for long-term JGBs by investors seeking to secure carry profits will keep 10-year JGB rates below 1.0% for a while," he said.

The five-year yield was up 3.5 bps around a one-week high of 0.345%.

The two-year JGB yield edged up 1 bp to 0.055%.

In domestic news, Japan's core consumer price index rose to 2.9% year-on-year in October, data showed on Friday, keeping inflation above the central bank's 2% target for 19 consecutive months.

The BOJ, however, has insisted it's largely driven by factors such as higher global commodity prices, rather than the stronger domestic demand and wage growth that it seeks. (Reporting by Brigid Riley; Editing by Mrigank Dhaniwala)
