Japanese night-carrier doctrine at Pearl Harbor

How would mature Japanese night-carrier doctrine and night-dropped torpedoes change Pearl Harbor?

A night-capable follow-up would greatly worsen American losses and could force the US Navy to develop its own night-carrier doctrine much earlier.

The scenario is heavily weighted toward Japan because darkness removes more of the defenders' warning and response time. Successful night torpedo attacks could leave the American battle line in even worse condition while making night aviation an urgent US requirement.
