TOKYO, July 25 (Reuters) - Japan's core consumer inflation eased slightly in the year to June, highlighting the challenges the central bank faces in meeting its 2 percent inflation target sometime next year.

But the slowdown will come as no surprise to the Bank of Japan, which has said inflation will continue to slow to around 1 percent in coming months as an increase in import costs from a weak fen fades.

The BOJ expects inflation to pick up again as a tight labour market lifts wages.

The central bank is thus in no mood to consider expanding stimulus any time soon, although some analysts warn it may face pressure to act if the economic recovery loses momentum and fails to nudge up prices late this year.

"Exports are weak and household spending - hit by the April sales tax hike - won't bounce back so strongly, which means the economy lacks a strong driver ahead," said Yoshiki Shinke, chief economist at Dai-ichi Life Research Institute.

"The economy may not recover as strongly as expected, which will certainly affect price moves," he said, predicting that the BOJ may ease policy in April next year if inflation fails to approach 2 percent by then.

The nationwide core consumer price index, which excludes volatile prices of fresh food but includes prices of oil products, rose 3.3 percent in June from a year earlier, government data showed on Friday, matching a median market forecast and slowing from a 3.4 percent gain in May.

Excluding the impact of a sales tax hike implemented in April, core consumer inflation slowed to 1.3 percent in the year to June from 1.4 percent in May, largely because rises in energy costs moderated from last year's sharp increases.

The government shared the BOJ's view that prices are rising moderately in its annual economic "white paper" on Friday, though it kept up pressure on the central bank to maintain its massive stimulus for some time as inflation remains well below its 2 percent target.

"The government has not officially declared an end to deflation, so I think that it is too early to debate about an exit strategy (from the easy policy)," Economics Minister Akira Amari told reporters after the release of the CPI data.

In one positive sign, core-core prices, which exclude both fresh food and energy, actually accelerated slightly, offering a hint of inflationary pressure in the economy.
