Japan is preparing for anything that North Korea may do if they make tests of ballistic misseles and they are worried that those tests may be similar to the one in 1999 when North Korea fired a missele that flew over Japan.
Better that NK doesn't make something foolish and fire misseles that may contain nuclear warheads instead of a simple test.
