it takes 10 years to do meaningufl part of focus tree.. Half of japanese focus tree is just jokes like +75% super heavy Battleship research bonus,
Extremley useless focuses such as but not limited to " Supremacy Of Technology,Bicycle Battalions , The Zero ( it takes billion years to reach that focus when you have to do industry focuses first...) Alliance With Siam ( you cant even puppet them ,you cant make airfields in siam, its just a joke ), Expand the SNLF( Yeay lets do that focus when we need 210 days worth extra focuses to attack china ) Supremacy Of Battle Fleet, The Japanese Settlement, Manchurian railways , Fortify Manchuria Border , The Manchurian Project , Sign the Tripatite Pact , Liatong Confrence, GReater Asian Co Prosperity Sphere , Strike South Doctrine Alliance with siam, Non Aggression pact with Soviet Union Bypass or push philipines, oh why are we even doign all these? solely because to get Tora,Tora,Tora spirit for 180 days at the far end that you get from doing Strike on the Southern Reseource Focus, you also have debuffs like militarism , and seperated fighter program and you got to do more even more useless crap like Unified Fighter program to get rid of +10% plane research time debuff, you wanna do fighter focus before 1939? you cant you will have no industry you will have no extra research slot, you prob wont even do marco polo, it is just horrible
Multiplayer japan is a total joke, basicaly you make air cas and kill china and then you use your op farmed land army leaders to do stuff other ppl cant do with your -75% cost for land stand , your navy is crap , your production-industry-reserach-doctrines , everything is crap and terrible , did i say that you dont even have a single carrier research bonus ? you know what that would be no issue if istarted with no carrier 2 researched but i had 95% research bonus for carrier 2 so i can atleast research it with pacific fleet designer...
Focus Tree obivously have not been really play tested, and made for people who play till 1947 considering how long it takes to do meaningful focuses...
Japan is absolutely unplayable in multiplayer in non low quality games, country is all about memes like kamikaze striking in british channel farming, level 8 leaders with op cavalry-infantry trait stacking that is made of mixture of all tanks (light,medium,heavy) so that divison is considered as still cavalry and get both cavalry-infantry traits, last standing forever with your -75% cost for last stand, except most of these are banned anyway multiplayer enviroment...
Japan is made with absolutely 0 thinking for a balanced game and 100% based on solely roleplaying and memes...
Air? Research is absolutely horrible you got a focus that gives you zeros but you got to do billion focuses to even attack allies, And everyone that makes navy will have carrier fighter II anyway, it is just a joke it is made so that japan can not manually research anything properly and have to do milliion useless stuff like carrier warfare experiments and first air fleet, Do paradox know what does Soriet EFficency +20% do ? lemme tell you , it does nothing useful if your enemy is a human in multiplayer and have enough carriers + upgraded carrier fighter2s to kill all your planes, it simply gives bombing efficency , which is absolutely useless,
Land Army? It is super good if it is game that allows kamikazes, then you can fully ignore naval doctrine and just afk kamikaze with fighters because japan basicaly have the best Generals in the game, and best upgraded tanks due to how much xp they get, if it is not? you will get attacked by a usa with 20 carriers doomstacked ( when you have 1800 planes on air you just auto deorg enemy ships even after so claimed ships now fight to death if they are on no retreat) then he will convoy raid you to death in 3 months and then you can just leave from the game..
Navy? You should totally ignore navy in multiplayer, if rules allow kamiakze u can make/spam carriers to kamikaze everywhere, if rules dont allow you to you can just ignore navy since usa is a country with -40% base research time, can always have double your docks before war starts and for you to win navy againist him, he needs to be simply bad- not know vanilla navla warfare ( afk carrier spamming)
Did i tell you that you got no PP for anything? because you need to use 800 on decisions and everything costs more
if you have equal number of fighters againsit usa you will get 1--1.4 trade ratios againist usa in air combat , but in a normal game he will have more, your fighters will trade at 1 to 1 and you will run out fighters in combat before he does due to his superiror naval and land industry always/.
