Recent reports indicate that Japan's population is declining — by 2055, the number of people is expected to drop to 90 million. Researchers also predict the number of people under 65 will nearly halve, meaning fewer workers available to support retirees. Jeff Kingston of Temple University, Japan Campus, says part of Japan's problem is that it lacks a coherent national strategy for addressing the slow-burn population crisis.  "It is not rocket science to know what has to be done, but not enough has been done," he said. "The lesson for other countries is that when you see this coming down the road, you need to act."
