TOKYO, July 1 (Reuters) - The mood among Japan's big manufacturers' soured for a second straight quarter in the three months to June, a central bank survey showed on Friday, hit by rising input costs and supply disruptions caused by China's strict COVID-19 lockdowns.

But confidence among big non-manufacturers improved in the quarter, the "tankan" quarterly survey showed, suggesting service-sector firms are shaking off the drag from the pandemic as the government lifts curbs on activity.

Firms expect to ramp up capital expenditure and are steadily passing on costs to consumers, the tankan showed, suggesting the economy remains on course for a moderate recovery.

Analysts, however, warn of a murky outlook as growing fears of a U.S. economic slowdown and steady price hikes for daily necessities weigh on exports and domestic consumption.

"All in all, the tankan figures aren't too bad. The strong capital expenditure plan is a surprise and shows corporate spending appetite remains solid," said Yoshiki Shinke, chief economist at Dai-ichi Life Research Institute.

"But manufacturers expect to see profits fall, which could affect their spending plans ahead. Rising input costs and prospects of slowing U.S. growth also cloud the outlook."

In a sign of mounting inflationary pressure, separate data showed core consumer prices in Japan's capital Tokyo - a leading indicator of nationwide trends - rose 2.1% in June from a year earlier to mark the fastest pace of increase in seven years.

The tankan's headline index gauging big manufacturers' mood slipped to plus 9 in June from plus 14 in March, hitting the lowest level since March 2021. It compared with a median market forecast of plus 13.

The big non-manufacturers' sentiment index improved to plus 13 in June from plus 9 in March, just below a median market forecast of plus 14.

In a sign more companies were able to pass on rising costs to consumers, an index measuring output prices hit the highest level since 1980 for big manufacturers and the highest since 1990 for big non-manufacturers, the tankan showed.

Big companies expect to increase capital expenditure by 18.6% in the current fiscal year ending March 2023, much higher than a median market forecast for an 8.9% gain.
