Toyota Motor Corp.'s Lexus unit plans to open luxury stores offering consumers goods including coffee cups glazed with volcanic ash and Italian leather bags to help boost the premium marque's brand image worldwide.

Japan's largest carmaker will open its first Intersect By Lexus outlet in Tokyo's Aoyama district on Aug. 30, it said in a statement Wednesday. Lexus will add similar outlets in New York and Dubai, the company said, without specifying a time frame.

Lexus' marketing effort comes as the carmaker aims to raise its global presence, after losing its luxury sales crown in the U.S. to Bayerische Motoren Werke AG and Daimler AG's Mercedes-Benz for two straight years. Mercedes also leads the Toyota unit by deliveries in the home market.

"Lexus' successful debut in the U.S. hasn't been transplanted to its other markets, and its brand presence still needs a lot of work compared with BMW and other luxury brands," said Takaki Nakanishi, founder of Nakanishi Research Institute. "You can't expect to gain sales from simply opening a cafe, but it's definitely better than not having one."

In the U.S., its biggest market, Lexus sales have gained 12 percent to 141,446 units this year, outperforming BMW and Mercedes's growth in the same period, according to Woodcliff Lake, New Jersey-based industry researcher Autodata Corp. About half of Lexus' sales comes from the country.

General Motors Co.'s Cadillac marque is also targeting upscale U.S. buyers and posted 30 percent unit sales growth in the year through July, making it the fourth-largest brand by volume, according to data compiled by Bloomberg Industries.

In Japan, Lexus posted sales of 27,074 units through the end of July. That trailed the 27,828 vehicles delivered by Mercedes in the same period, the Japan Automobile Importers Association said.
