As long as they can sell enough sake, wages will improve, and everything else will be taken care of as well. He also feels that young Japanese today don't see the real charm of sake and the culture surrounding it as they consider it too much of an every-day thing. There are no good books on sake or baseball in Japan, as Japanese think they know all about it already. Tons of books. But not sake or baseball.
Fermented things work well.
Also, a bit of Japanese culture must be exported along with the sake, or it won't catch on. His opinions on the mechanization of brewing techniques are just as well thought out. Most of the developments over the last 500 years have been for the latter. But, he says, this tends to uncover ways to make better sake as well. One example is koji that is developed in small trays.
