Amazon Japan K.K. is running a bar in Tokyo's posh Ginza district for 10 days through Oct. 29, with the aim of promoting a broad lineup of alcohol products the online shopping giant offers, in addition to its traditional business of books and commodity goods.

Inside the "amazon bar," shelves are lined with around 5,000 bottles of wine, sake and other alcoholic beverages, and customers order a drink using a tablet, which asks them a set of questions about their preference and mood for the day to show beverage recommendations that fit their tastes.

"With our online shop, it's hard to recognize the abundant lineup (of alcohol products)," said Hiroshi Maeda, a manager of the company's consumption commodity operation, showing the large shelves that fill the bar's wall.

By opening the bar and also using social media for advertising, Amazon Japan is aiming to encourage people who have been using conventional liquor and supermarket stores to try its online shop, he said.
