The benchmark Nikkei 225 index was down 0.21 percent or 49.71 points at 23,128.39 in early trade, while the broader Topix index lost 0.06 percent or 1.01 points to 1,629.71.
"There is a sense of overheating in the Japanese market which is prompting sell orders despite support from rallies in the US market," said Mizuho Securities, adding that a higher yen against the dollar is also weighing on the market.
