>>53642803Tomiyasu is the head of all direction, he is in the same place as Yuyama before JN.
Basically he was the one that oversaw all management of the JN series.
Firing of Kodaira and Owada is maybe his initiative, but why does that ever happen? It also probably his fault that Owada/Kodaira unable to cope with pandemic/going too slow in series execution.
