Were German and Japanese naval chiefs surprised by war?

Were the German and Japanese naval chiefs surprised when their governments went to war earlier than expected?

Germany's chiefs were, but Japan's were involved in the collective decision and removed many of the opponents.

German naval leaders were surprised because their force planning assumed a later war. Japan's senior naval leadership was less surprised. Its chiefs participated in the collective decision over when to fight. Officers who opposed the choice were pushed out of influence. The contrast separates being overtaken by a government's timetable from helping create that timetable.
