Says the article:
Salarymen go out drinking on average 2.9 times a month, spending about 4,190 yen ($46) each time, a 19 percent decline from a year earlier, according to a Shinsei Financial Co. online survey. That buys five pints of Sapporo Draft at Coopers, a British pub, in central Tokyo.
The article goes on to say that a few restaurant operators are planning to open new low-cost chains, while other eateries will offer "one-coin" lunches.
Another point in the article: It is usually wives who handle household finances, so the salarymen are getting shut down when they ask for more spending money.
I propose a deal with the wives, which goes something like this. They hand over a few extra thousand if the husbands agree to stick to craft beer.
