Iam starting to think that you guys do not know the real power of the Kamikaze.
The real power of the Kamikaze is that it stops shore bombardment.
Lets use this as an example.
USA decided to go into SZ6 and invade Japan.
USA pushes all in and in a grand fashion pushes their units onto the shores of Japan. The USA has 3 BB and 5 CA and they are counting on those units to push the odds in their favor, DD and CV in the SZ do not matter.
Japan launches 1 Kamikaze into the SZ. It does, what ever it does on its epic 1-2 roll. It did its job though regardless of if he hit or not. Now the USA cannot shore bombard.
The role of the Kamikaze is to protect all Japan islands from assault by denying the invader from using shore bombardment. In essence Japan can protect it self from 6 invasions if you use just 1 Kamikaze per invasion.
So, the power of the Kamikaze is that it forces, lets say the USA, from having to invade islands with enough force by just using ground forces and any air assets they have in range.
The Kamikaze rules really beef up Japans defense of Japan, Phillipines and Iwo Jima IF Japan actually puts some garrison units on those key islands. Which, IMO, the vast majority of players refuse to do. The action is in China and India, no need to leave lets say, 6 INF on Iwo Jima or the Phillipines.
Lets take a look at the Japan homeland, the most common scenario. There are times during the game that the USA could jump from Hawaii to Japan with lets say 4inf and 4 art, plus 2 BB and 4 CA. Japan only has 6 IINF, 4 ART and 1 FTR. Well that is around a 50/50 battles with the shore bombardment. Now japan could scramble its FTR to SZ6 to defend the invasion and deny the shore bombardment but that really weakens the defense of Japan. That is where sending out just 1 Kamikaze comes into play.
It is a free move by Japan, they have 6 free Kamikaze strikes. So, the Kamikaze would deny the shore bombardment, the FTR stays on Japan to help in defense, the USA knows this and calculates the odds of the quick strike, caught them napping on the homeland plan and realizes it is a lost cause and does not invade.
