The dealer bulletin reported that:
"・if the idling speed may not drop. Reset the ECU (re-learn idling) to return the idling to the proper speed."
Whereas
"・If the idling speed is lower than the specified value, initialization is performed instead of ECU learning."
I am not sure what "initialization" means.
From what I read, it is a dealer job that requires the HONDA MCS.
The general consensus and feedback from Japanese owners who have had their ECU "reset" is positive and they reported no more issues after.
Here's a link to another post from a Honda shop mechanic that recommends the procedure. Google translate will work sufficiently:

Just to help with translating the text on the Honda MCS tool.
In the third picture, the table shows that an ECU update 3 is available
The final picture below simply says "Updating control module, please do not turn off the ignition. Do not remove the battery"
