In its cover story last month, The Economist newsmagazine looked at the issue of "Asia's lonely hearts: Why Asian women are rejecting marriage and what that means." It offered many reasons — including economics, education level, changes in family structures and gender roles, divorce difficulties, and demographics — for why many Asian women (and of course, by extension, Asian men) are marrying later or not at all.

I commend The Economist's well-intentioned attempt at dealing with an important social issue. But its discussion left one major stone unturned: sex.

At the risk of turning this month's scribbling into a Hugh Hefner column, I think it incumbent upon those of us planning a life in Japan to consider a fundamentally unhealthy social phenomenon: how sexuality in Japan is downplayed, if not encouraged to be omitted completely, from many married lives.
