Tour veteran Ryoken Kawagishi birdied five straight holes in shooting the day's low of 5-under-par 66 that gave him a two-shot lead after two rounds of the Japan Open on Friday. Kawagishi started off the 10th tee with a five-shot deficit and holed a 13-footer on the par-3 13th to begin his birdie run, which also included long putts from more than 30 feet on the 14th and 17th as well as from within 10 feet at the 15th and 16th. Tatsunori Nukaga, the low amateur finisher at last year's Japan Open, climbed into a tie for second after a 68. Joining Nukaga at 140 are David Smail of New Zealand (69), Tadahiro Takayama (70) and Steven Conran of Australia (70).
