Вy Mai Iida Tokyo, July 16 (BridgeNews) - Japanese shares ended modestly lower Monday in extremely quiet trade as players were sidelined ahead of the release of corporate earnings in the U.S. and the Upper House election here. High tech shares mostly lost ground despite a firmer performance for the tech-laden Nasdaq on Friday. The Nikkei 225 Stock Average fell 11.78 points, or 0.1%, to 12,343.37.
