  • With no room left to cut, it was the only tool available
  • A deposit paying nothing sends money into shares, and foreign money came in heavily
  • Technology was rising worldwide at the same moment, so Japan's telecom and electronics names rose with it
  • No single trigger can be pinned to this day
  • In this stretch the index was 12.99% below its peak
