Some 88 percent of major Japanese companies surveyed expect the economy to grow by the end of 2015, and nearly half of them plan to boost capital spending in the business year through March, a Kyodo News survey showed Saturday.

The results of the survey indicate domestic firms are generally optimistic about the country's economic prospects, despite weak consumer spending and increasing uncertainties about China.

Of the 108 companies surveyed between late July and mid-August, including Toyota Motor Corp. and Sony Corp., 95 firms said they think the economy will expand by the end of this year, of which 89 expect moderate growth. Seven firms said they expect growth to be flat, while only one projected a moderate slowdown.
