Honda Point and the discipline of navigation

What lessons followed the Honda Point disaster, and how quickly were they adopted?

The lessons emphasized navigation training, duplicated checks, and command responsibility, but no implementation timetable is given.

Navigation errors and the need for better training dominate the explanation of Honda Point. Unusual currents were attributed to the Great Kanto earthquake, alongside mistakes by the squadron's navigators. Watson and Hunter, identified as the squadron commander and squadron navigator, accepted responsibility for the failures. More navigation training and duplicated checks were the practical lessons emphasized. The answer does not establish how quickly those changes were implemented.
