TOKYO, Jan 8 - Tokyo's Nikkei stock average snapped a two-day losing streak to close up on Thursday after a rally in the U.S. Nasdaq index boosted investor confidence and sent Sharp Corp <6753.T> and other technology shares higher. The Nikkei average <.N225> closed up 0.74 percent at 10,837.65. Analysts said the Nikkei had lost 0.62 percent over the previous two sessions, nearly erasing the sharp rise it made at the start of the year and suggesting the index had declined enough for now. The broader TOPIX index <.TOPX> also rose 0.51 percent to 1,056.92.//
