TOKYO, July 31 (Reuters) - The Nikkei average fell 0.6 percent on Thursday, dragged lower by Komatsu Ltd <6301.T> and and Denso <6902.T> as investors punished companies with disappointing earnings which sparked concerns about the broader economic outlook.
But investors picked up stocks more reliant on the domestic economy such as Fast Retailing Co <9983.T> amid fears of a global economic slowdown, while energy-linked shares rose on a jump in oil prices.
"The focus of trade is shifting toward defensive sectors or stocks that are less affected by external factors, rather than those of a cyclical nature," said Takahiko Murai, general manager of equities at Nozomi Securities.
"Komatsu's earnings rather shocked the market. Komatsu, which is supported by demand in emerging countries, was a bellwether cyclical stock. Investors were forced to admit that the global economy had slowed more than expected."
Construction machinery maker Komatsu booked a 2 percent gain in quarterly profit on Tuesday, but slashed its unit-based demand forecast for the U.S., European and Japanese markets.

DENSO, KOMATSU DOWN
Denso shares plunged 7.8 percent to 2,775 yen, and has lost 11.6 percent since the world's top auto parts supplier reported on Wednesday a more than 20 percent fall in quarterly profits -- considerably worse than expectations.
