For the government, the declining birthrate and delayed marriages are its biggest headaches as the graying of Japan accelerates.

But for Jim Safka, chief executive officer of Match.com, that pain is his gain because it gives his U.S.-based matchmaking firm an opportunity to expand business in Japan.

"We are in the business of creating couples and creating babies. Solutions we provide are a perfect fit with the social changes we are trying to counteract in Japan," said Safka, who was in Japan for four-day visit through Saturday.
