Care-related firms are trying to expand operations aimed at preventing the physical and mental deterioration of people insured for nursing care, in line with the government's plan to reform the nursing-care insurance system in fiscal 2005.

Nursing grants totaled 3.2 trillion yen in fiscal 2000, when the insurance system for nursing care was inaugurated. These grants are expected to reach 20 trillion yen in fiscal 2025.

The government is reviewing the system to prevent the insurance budget from worsening by expanding preventive care, official sources said.
