Japanese real ales made their debut at this year's Great British Beer Festival in London.

Toshi Ishii, 38, a brewer from Nagano Prefecture, has been selling two of his most popular brands of real ale and the response from British connoisseurs has been favorable.

Last week was the first time Japanese ales have been featured at the five-day event. With more than 50,000 visitors, it is one of the biggest beer bashes in the world.

As well as British beers, the festival featured ales from around the world, especially from the Czech Republic and Germany.
