Also, everytime the emperor decides to rename the country (which happens twice) all your territories dont suddenly reset two ticks if you have japanization. So you have your 25 territories and then suddenly next turn only 5 of them are producing income. good times.
Still, if you are going Scarlet (i.e. wife route) you have no choice but to go non-Japanization
simple breakdown:
Dokotsu Route-Join Axis, have a territory next to the German territories before they die
Empress Route-Japanization, do not go into Dokotsu Route, have high amounts of cherry blossoms on your cities
PseudoEmpress Route-Have low amounts of cherry blossoms (like 30%, so no more than 10 or so)-gives you 20% shipbuilding reduction on next games so its pretty legit to have
Scarlet/wife Route-Go non-Japanization, defeat one of the Allies (well, not France). Then fight your wife with Togo in command and beat her 3 times.
Scarlet Route is subdivided even further (cheat on her, don't cheat on her, your kid) but we're not going into those details.

Franklin Insaneovelt-attack Gamerica from Hawaii --> Kanada (es funny and yet kind of depressing)
