TOKYO, March 27 (Reuters) - Japan's Nikkei share average edged up on Friday morning in choppy trade as investors bought stocks on the dips after the previous day's falls, while Panasonic Corp attracted buying after it announced an acquisition plan.
The Nikkei benchmark .N225 rose 0.4 percent to 19,548.48 in mid-morning trade, after diving 1.4 percent on Thursday, the biggest daily drop in 10 weeks. It also slipped from its 15-year high of 19,778.60 hit on Monday.
It has been flat for the week.
Analysts said profit-taking was natural as the Nikkei has hovering at 15-year highs recently.
"When the benchmark falls 300-400 points from its peak, the market is comfortable with buying back," said Hikaru Sato, a senior technical analyst at Daiwa Securities.
He added that views on the Japanese market remained positive based on hopes of buying by Japanese pension funds including the Government Pension Investment Fund as well as expectations for better shareholder returns and rosy corporate earnings.

Other exporters were mixed, with Toyota Motor Corp 7203.T falling 0.6 percent, Honda Motor Co 7267.T was flat and Sony Corp 6758.T rising 1.9 percent.
Bucking the trend, Toshiba Corp 6502.T dropped 3.5 percent after SanDisk Corp SNDK.O cut its revenue outlook and its shares tumbled 18.4 percent overnight. SanDisk buys wafers for its NAND chips from a joint venture with Toshiba.
Japan's consumer inflation data out earlier in the day had little impact to the stock market. The headline core CPI, which includes oil but excludes volatile fresh food prices, rose 2.0 percent on-year in February, short of a median forecast for a 2.1 percent rise, government data showed.

The broader Topix .TOPX rose 0.3 percent to 1,573.55 and the JPX-Nikkei Index 400 .JPXNK400 added 0.3 percent to 14,316.31.
