Tokyo stocks fell on Friday, snapping a four-day winning streak, with investors cautious ahead of a potentially contentious Group of Seven summit and a historic US-North Korea summit. The benchmark Nikkei 225 index slipped 0.56 percent, or 128.76 points, to close at 22,694.50, but was up 2.36 percent over the week.
The broader Topix index was down 0.42 percent, or 7.57 points, at 1,781.44, logging a weekly gain of 1.84 percent.

SBI Securities also said in a commentary: "A wait-and-see mood is likely to spread as it is difficult to take positions actively as investors wait for the outcome of the G7 meeting in Canada (this weekend) and the US-North Korea summit on Tuesday."
