* July household spending down 0.2 pct yr/yr vs f'cast +0.7
* Jobless rate flat, job availability at 43-year high
* Inflation remains subdued despite strengthening economy
TOKYO, Aug 29 (Reuters) - Japan's household spending unexpectedly fell in July from a year earlier after last month's spike, casting some doubt on the sustainability of a domestic demand-driven economic recovery.
The data keeps pressure on policymakers betting that a tightening labor market will boost wages and lift consumption, thereby allowing companies to raise prices and help the Bank of Japan achieve its ambitious 2 percent inflation goal.
Household spending slid 0.2 percent in July from a year earlier after hitting a two-year high in June, government data showed on Tuesday, confounding a median market forecast for a 0.7 percent increase.
The jobless rate was flat at 2.8 percent in July and 1.52 jobs were available per applicant, the highest since 1974, separate data showed, a sign the economy continued to enjoy what many analysts consider as near full employment.
Japan's economy expanded at the fastest pace in more than two years in the second quarter as consumer and company spending picked up.
But price and wage growth remain stubbornly weak with firms still wary of passing on profits to employees, raising doubts over whether the second-quarter's bounce can be sustained.
Core consumer prices rose 0.5 percent in July from a year earlier, marking a seventh straight gaining month but still quite a distance from the BOJ's 2 percent target. (Editing by Shri Navaratnam)
