NIHONMATSU, Japan — As Japan confronts troubling economic data and memories of its stagnant “lost generation,” the country’s government is offering a little something to take the edge off: a bottle or two of sake.

Around the country at international airports, the government is helping to fund tasting booths where travelers can sample sake, an alcoholic brew made from fermented rice. On a recent morning, an attendant at a booth at Narita Airport near Tokyo explained that most high-quality sake is intended to be drunk slightly chilled — not heated, as lower-grade sake is sometimes offered at restaurants outside Japan.

The program, set to run at least until March, is part of a broader push by the government to bring the country’s cultural products to the world — and in doing so, hopefully, give a little lift to Japan’s export economy. A government-financed program called Cool Japan looks to champion the country’s softer goods, like anime, music, fashion, food and drink. In December, Japan secured “intangible cultural heritage” status for its traditional cuisine, known as “washoku,” from the United Nations Educational, Scientific and Cultural Organization.

Japan has been taking a broad approach to reviving its moribund economy. In the face of persistent deflation, Prime Minister Shinzo Abe has introduced his “three arrows”: fiscal stimulus, monetary easing and structural reform.
