SYDNEY, July 18 (Reuters) - Asian shares tracked Wall Street higher on Friday as still-strong U.S. economic data and robust corporate earnings offset tariff worries, while the yen headed toward a second successive week of loss ahead of Japan's upper house election.

Overnight, the S&P 500 and the Nasdaq again closed at record highs as U.S. data including retail sales and jobless claims beat forecasts, indicating a modest improvement in the economy that should give the Federal Reserve time to gauge the inflation impact from higher U.S. tariffs.

Streaming giant Netflix NFLX.O beat Wall Street's lofty expectations for second-quarter earnings in part due to a weaker U.S. dollar. Its share price, however, fell 1.8% in after-hours trading, with analysts saying much of the growth had already been priced in.

On Friday, MSCI's broadest index of Asia-Pacific shares outside Japan .MIAPJ0000PUS rose 0.8% to its highest since late 2021, bringing the weekly gain to 1.7%.

Japan's Nikkei .N225, however, slipped 0.2%, and the yen JPY=EBS was at 148.54 per dollar, down about 0.7% this week after polls showed Prime Minister Shigeru Ishiba's coalition was in danger of losing its majority in the election on Sunday.

Data on Friday showed Japan's core inflation slowed in June due to temporary cuts in utility bills but stayed beyond the central bank's 2% target. The rising cost of living, including the soaring price of rice, is among reasons for Ishiba's declining popularity.

"If PM Ishiba decides to resign on an election loss, USDJPY could easily break above 149.7 as it would usher in an initial period of political turbulence," said Jayati Bharadwaj, head of FX strategy at TD Securities.

"JPY could reverse the recent dramatic weakness if the ruling coalition wins and is able to make swift progress on a trade deal with Trump."

Chinese blue-chips .CSI300 rose 0.3% while Hong Kong's Hang Seng index .HSI gained 1.2%.

The Tapei-listed shares of TSMC 2330.TW, the world's main producer of advanced AI chips, rallied 2.2% after posting record quarterly profit on Thursday, though it said future income might be affected by U.S. tariffs.

In the foreign exchange market, U.S. the dollar =USD was on the back foot again on Friday, having bounced 0.3% overnight against major peers on the strong economic data. For the week, it is headed for a second successive gain of 0.6%, bouncing further from a 3-1/2 year low hit over two weeks ago.

Fed Governor Christopher Waller said on Thursday he continues to believe the central bank should cut interest rates at the end of this month, though most officials who have spoken publicly have signalled no desire to move.

Fed funds futures imply next to no chance of a move on July 30, while a September rate cut is just about 62% priced in.

Treasury yields were slightly lower in Asia. Benchmark 10-year U.S. Treasury yields US10YT=RR slipped 2 basis points to 4.445%, having moved little overnight. Two-year yields US2YT=RR also edged 2 bps lower to 3.8981.

Oil prices were mostly steady on Friday, after gaining $1 overnight following a fourth day of drones strikes on Iraqi Kurdistan oil fields, pointing to continued risk in the region.

U.S. crude CLc1 inched up 0.2% to $67.66 per barrel and Brent LCOc1 also rose 0.2% to $69.68 a barrel. They, however, lost about 1% for the week.

Spot gold prices XAU= were steady at $3,337 an ounce but were set for a 0.5% weekly loss.
