TOKYO, June 29 (Xinhua) -- Tokyo stocks closed marginally higher Friday as the market mood was lifted by a comparatively weaker yen, but gains were capped by ongoing concerns about trade tensions.

The 225-issue Nikkei Stock Average gained 34.12 points, or 0.15 percent, from Thursday to close the day at 22,304.51.

The broader Topix index of all First Section issues on the Tokyo Stock Exchange, meanwhile, closed 3.89 points, or 0.23 percent, higher at 1,730.89.

Local brokers said that in choppy trade and a risk-off mood, shares closed higher as investors bought back issues on the yen's retreat against the U.S. dollar, following news that at a summit in Brussels, European Union leaders had reached a consensus on migration policy.

A weaker yen against its major counterparts often lifts the market mood as firms widely exposed to overseas markets see their profit outlooks boosted as well as their competitiveness and yields are augmented when repatriated on favorable exchange rates.

Investors, however, despite exporters advances often having a bearing on the broader market, opted for a wait-and-see stance amid ongoing trade tensions.

They chose not to chase the market higher as they eyed upcoming developments, market strategists here said.

By the close of play, pharmaceutical, textile and apparel, and nonferrous metal-linked issues comprised those that gained the most, and rising issues outpaced falling ones by 1,167 to 829 on the First Section, while 96 ended the day unchanged.

On the main section on Friday, 1,288.24 million shares changed hands, dropping from Thursday's volume of 1,400.40 million shares.

The turnover on the final trading day of the week came to 2,298.6 billion yen (20.77 billion U.S. dollars).
