TOKYO, April 14 (Reuters) - Japan's Nikkei rose for a second session on Thursday, boosted by tech shares and travel stocks as they tracked overnight gains on Wall Street.

The Nikkei ended the day 1.22% higher at 27,172.00, closing north of the psychological 27,000 level for the first time since April 6. Of its 225 components, 201 stocks rose, while 21 fell and three were flat.

"While the main part of yesterday's Nikkei gains was just a knee-jerk rebound off the low, today it's reflecting what happened in U.S. stocks, and there are signs of a potential recovery trend," said a trader at a domestic securities firm.

Uniqlo store operator Fast Retailing led advancers by index points, gaining 2.14% ahead of after-the-bell financial results. The company saw first-half operating profit climb 18%.
