Tojo shot first and sunrise Invasion achievement guide.

Tojo shot first and sunrise invasion can be done together in a natural way. This guide will give you the information I struggled to get without having to struggle like I did! How legit is that?

The ins and outs of it all.
1. Start with the focus Army exp Law. You will need this Army xp to change over your div templat to 7 inf with support arty and eng platoon. While doing this, you MUST spend your 1st 40 political power on declairing war on the Philippines. Doing it this way will keep world tension very low. The US will defend them. World tension will only grow to around 12% when the US joins. This prevents them from joining the Allies and gives the US less time to build up. Start the war ASAP. You dont want to waist any time. The next few steps will tell you what you should do during the build up to war.

Also, work on building military factories, focus on military / industry tech, produce more ships for the main navy fleet, inf equipment, arty, support equipment, and have 1 factory in naval bomber and naval fighter. Continue your focus by following the right path after going for Army exp Law. This is to give your army a boost. Once you do that just go down the normal focus tree as fascist Japan but do not create or join any factions.





2. Change over about 15 div to the cav template. split them into 2 groups. One for island port guard and one for the main island port guard. You want to guard every island in the Mariana region and the island in the China sea. (PS, when you can, change over the 6 cav units to 5 inf units to save equipment)

3. The rest of your remaing army will all be the inf div template with 7 inf units with arty and eng support. Split into 3 groups. one with 10 div. Plan a naval invasion from the most northern port you have with this group of 10 to the west coast of Alaska. IMPORTANT. Give this group the general with the leader trait "out of supply -50%" They will need this to get to the port in Alaska and fight off any US forces. Train them up untill they have the 25% bonus.

The final 2 groups will be split even. Give these 2 groups leaders with few or no negative traits. Train more div untill you have at least 2 groups with 24 and the one group with 10 div.



4. In the Mariana islands, you want any extra aircraft you have to perform missions there. Either air cover or naval strike. Remove all your aircraft from china and Japan and use them here. Just be sure your aircraft carriers still have aircraft in them.

Split your navy into 2 gropus. One small navy with 40 ships. Give this group only 1 battle ship and fill up the rest of the group with smaller ships. Give it a decent mix but at least half will be destroyers and subs. The larger group will keep the rest of the fleet. The larger navy will search and destroy in the Mariana islands zone. In most games, the US will send its navy to slug it out here. There will be a few small battles but in time there will be a major battle. This battle will knock out much of the US fleet. This is what you want. The smaller group will run convoy protection in the North Emperor Chain, Bering Sea, and Sea of Okhotsk. This group will protect your units as they invade Alaska. Even though this group is small, the US does not send large groups up north. More so when they lose alot of their navy in the Mariana islands zone.



While all of this is set up and going on, be sure to send your naval invasion to Western Alaska. You can also have your main fleet guard the Western North Pacific after the major naval battle. After taking Alaska, plan a naval invasion from Alaska to the west coast. Move your other units to Alaska while the naval invasion is building. By the time you send the invasion, you should protect the rout with the smaller navy like last time. Also, the rest of your army should be making its way over to Alaska. Dont wait till you take the port on the West coast to start sending the bulk of your army. Once youtake a port on the west coast, rout the bulk of your army to the west coast port. Be sure to protect your army with both the large and small navy.





5. Once your 1st group lands on the west coast, give em space and rush to take a 2nd port ASAP. Once you do just stay put till the rest of the army gets there. After your army is ready and lined up, start to push while trying to cut off US forces. Kill as many as you can. Move your main navy over to guard the west coast and have your smaller navy guard more div coming over to the US. Push as fast as you can to take all the west coast ports. Once you have them all and you have at least 60 div, push east. If everything goes good, the US will have a weaker navy than you and a smaller army. Push while trying to cut off more and more forces. If the US focused on its navy and not its army, they will fall pretty easily. Sometimes they dont send their navy out to fight and keep it in port while building a large army very fast. In this case you can still win but it will be much harder. If the US goes the normal rout and sends its navy in to fight you at the start and does not build up its army fast, you can annex the US before the end of 1938. If the game goes until the Allies go to war with the Axis, the US will join the Allies and this will get very hard.

Side note, you may want to protect the 1st 2 ports you get. Sometimes, the US will naval invade their own coast line.





6. Now that you have Annexed the US, the hard part is done. Dont worry about Asia unless you feel like it. Just focus on getting nukes now while starting a new war on Mexico ASAP. Just take out Mexico using the US Southern boarder. After taking Mexico, help the Allies take out Hitler. This will be much easier because your navy will have no problem protecting convoys. Once you take out the Axis, just take at least 1 coastal state and you are done with the Sunrise invasion achievement.

7. Here is the boring part. Just keep playing untill you get a nuke (taking on China can fill this time). Once you do, let the US go. Dont make it a puppet. Just let it go. Use Mexico as an airfield. Go to war with the US and nuke them. Because they were Annexed, they never built up their atomic tech so there is no way they can get a nuke before you. Just let them go and go to war. Drop a nuke on them and you are done.

I hope this works for you. Maybe not the 1st time but this does work. I have pulled it off a few times and this is pretty much how I play Japan world conquest games now. Have fun!

An alternative to invading Alaska is to go from Marshall Islands to Hawaii, ask El Salvador for port access and split all your heavy ships into a separate group and dock them in San Salvador. Now you should have enough naval range between your two fleets to hit all the sea tiles between Hawaii and Los Angeles/San Diego. Los Angeles is a level 10 port so at that point you won't have any supply bottleneck issues from the port, although you'll want to split off screens to protect your convoys across the Pacific. I'd suggest restricting sea zones so they have to sail by Hawaii to make it easier to protect them.

Update.

I would prob not bother using the 7/2 template anymore because the upcoming supply changes and overall lack of effectiveness vs their supply use. It will prob be best to use full on 10 inf div 20 with spam with support arty, recon, and engineering company (this could change seeing how there will be changes to how combat width works as well but for now just go with a normal 20 width). You will be able to push out more of these divisions and they will use less supply in the West coast for sure. Mostly that would be all I might change for the next update. As a side note, you could also take out Spain for the coastal province seeing how they will be stuck in a civil war or weak due to it. Portugal could work too but don't forget they could very easily end up joining the Allies, especially if the UK calls them in with their unique decision option so just be aware of that possibility. Have fun y'all!

@Yamantaka I get what you are saying but I think this is how the game should have came out. Hoi4 was always kind of a map painting game. Win a war and take what you can and thats it. After the war everyone just accepted your rule. In reality, that is not how war works.

Now yes you get less overall factories than before (you can get most the factories though over time) but in late game as any major, factories were not really an issue. Manpower was. This update makes it to where you can gain more manpower than before through compliance.

I think the game has more depth now and blobbing has consequences now where before it really didnt so I like the balance now. The USSR and Italy need to be reworked though now for sure

I feel the game has fallen apart with the latest patch, conquering territories only gives you a fraction of their factories, so I feel the entire rhythm of conquest has been disrupted.

For anyone using this guide in 2020, I would change who you go after in WW2. It might be best now to just go after the UK and not Germany. Germany protects its ports much better now and you can deal with the UK Navy by spamming fully upgraded subs and using German airports with naval bombers. Either way can work but Germany is harder to invade than when I 1st made this guide.

Then again, if Germany shits the bed against the USSR, just go after Germany. Might just have to nuke them a bit 1st.

@SoldatNr444 Hahaha funny enough, I was just wondering how much this guide would have changed if I made it today. Not much honestly. Maybe do some spy stuff but it might not be worth it all too much. Mostly just worry about oil a bit more lol

Glad its still useful. I just finished my last achievement for La resistance so maybe I will make another guide. Maybe not lol

Thank you very much sir! This guide still works. I'm far from being a pro, i never managed to overwhelm the usa with japan but this guide did it for me :mailedfist:

Easier to attack Portugal than to attack Allies or Axis in Europe
Kalle 2018 年 10 月 13 日 上午 3:54 
@atxgodzilla I definitely see why that´s easier :D
ATXGodzilla  [作者] 2018 年 10 月 12 日 下午 8:20 
@Kalle I would rather fight the Axis navy to do a naval invasion than the allies. Either way works but its easy vs the Axis.
