Japan bond yields hit 30-year high on debt fears

Rising yields on Japanese government bonds signal growing pressure on a country carrying one of the world's largest debt loads relative to GDP. The move is being watched closely by global markets, as Japan's ultra-low-rate era has long been a pillar of international financial stability.
