Japanese Tactics

It seems like there are a lot of 'tactics' floating around. Here is a thread for Japanese Tactics. Of which I will mention a few...
***ASW Tactics***
Even though the Japanese are heavily out gunned in the Submarine conflict, you can do things to slightly minimize the damage.
1. Assign H6K and H8K Air Groups to bases along the Palambang-Nagoya Sea Route. Recon aircraft will attack Subs only at 50% of their range. Using these Long Range aircraft as ASW is your best option. However, you will lose their ability as Long Range Scouts. Solution? Use the many E13A Jake and Ki-64-II Dinah groups for recon since their ASW abilities are poor-zero.
2. Assign all old IJN DD's to Nagoya for escort duty (Kamikaze, Wakatake, Minekaze). Keep the Mutzuki Class in the 'field' since they have a good cargo capacity and have Long Lance Torpedo's (would hate to lose these on convoy duty!).
***Oil Saving Tactics***
1. Use only your best ships, leave the others at port. Keep your slow battleships (Yamato, Nagato, Fuso Class) as well as weak Cruisers (Aoba, Tenryu) in port and rely on your good quality ships for the main fighting. The fewer ships you use, the less oil you eat up. Avoid 'Midway Type' operations where 90% of your fleet is out.
2. Use your Fleet Oilers and Type 1 TL tankers as emergency convoys directly from Palembang to bases in need of fuel. Use your smaller tankers on regular convoy phase duty.
***Convoy Tactics***
1. When creating a convoy that might go into enemy waters you should do the following. Give it a strong escort. There are many ships who are useless in anything but convoy duty. The Katori class (Katori, Kashii, Kashima, Okinoshima, Tsugaru, Ioshima and Yasoshima [last four were virtually identical to Katori Class]) is useful for Convoy leaders, since they gain the advantage of high numbers of 25mm given to IJN CL's in 1944, but lack due to their slow speed. Add the Mutsuki DD as these types of escorts, since if ever engaged in surface combat they have Long Lance, plus they are sufficiently weak enough not to be needed in the main fleet.
***Fleet Tactics***
1. Unlike the USN, have the IJN CVE's act as fleet carriers. Although they have a pitiful air compliment, an extra TF of 4 CVE's could turn the tide of battle. Immediately start training their air groups up to the standard of the rest of the fleet. However, like the Junyo Class they tend to be only a one shot deal, usually dying in their first battle. Use them wizely.
2. Divide up the carrier fleet into groups of 2 CV and 2 CVL/CVE. Here are the best combinations...
CV Akagi, CV Kaga, CV Shokaku, CV Zuikaku (under command of a level 7 air commander)
CV Hiryu, CV Soryu, CVL Zuiho, CVL Ryujo
**CV Junyo, CV Hiyo, CVE Taiyo, CVL Hosho
**This TF is an excellent decoy TF. It appears to be strong when the Allies look at it on the map (2 CV, 2 CVL) but it contains your weakest ships of that type. A good tactic is to assign this TF a target base, but have its standoff at maximum (like around 12). If the Allies use signit on this TF, it shows its makeup (CV TF) and its destination (allied base) but not its standoff range. You can then trick the Allies into thinking that you are attacking Midway when you are really after Palmyra.
(another decoy tactic)
When against an allied player, signit also tells the Allies what the target base of your certain HQ is. Targetting this base, even when the HQ is on full control gives troops attacking that base a bonus. An alternate tactic is to target bases you are not focussing on, but are potential targets.
3. Hide the AV's Nisshin, Mizuho, Chitose and Chiyoda. If not sunk, by December 1943 they will all be changed into CVL's. Keep them located at some base in Japan so they would not accidentally get sunk as AV's.
4. Once the F6F Hellcat appears, withdraw your CV TF's from the main fight. The A6M5 cannot hold itself against the F6F and even well trained air groups will be slaughtered. When the F6F appears, your CV TF's will only be useful if they have overwhelming experience, or if they catch a much weaker force.
***Defense Tactics***
Even though many people believe that it is impossible for Japan to win unless they defeat the Allies in 1942, causing sufficient casualties can result in a tie/marginal Japanese victory.
1. Immediately defend the Marianas. Place 3 of your good Divisions directly on Tainan, Guam and Saipan ASAP. Have the airbases and ports brought up to their highest numbers. The Marianas are perfect bases in which to bomb Japan, holding them is critical. Save some high quality LBA from the battles in South East Asia and the South/Central Pacific for specific defence of the Marianas. Have a mix of IJNAF bombers and IJAAF fighters (IJAAF fighters are more durable and can take more punishment, plus better ones appear sooner than IJNAF).
2. Stop your advance at Bangkok. Sure, you don't get to smash some British units, but you tend to get stuck at Mandalay anyway. Defending at Bangkok is your best bet. It is too far away from Moulimien/Rangoon to be attacked by allied fighters (but close to IJAAF bases in Indo-China and Malaya), and if the RN comes to bombard your troops they have to go around the Malaya Peninsula. You can effectively hold off the British with 2 Divisions in Bangkok, plus 2 Divisions in Northern Malaya to guard against a possible landing. This will eat up the 4 original divisions given to 15th Army, but any new formations (including the 2 new Indian National Army Divisions) can be used elsewhere, or used to replace high quality divisions on garrison duty. This frees up more troops, aircraft and ships to fight the 'real enemy'.
3. Once the P-38J and F6F appears move all of your A6M groups back to Japan. They are useless. The F6F not only has better manuverability, but better armour and cannon rating. A moderately experienced group will kill an elite A6M group. Wait until you have N1K's before your IJNAF LBA ventures out of Japan. What do you do in between? Send the IJAAF to do the real fighting. The Ki-44, Ki-45 and Ki-61 are much better at fighting off the P-38 and F6F than the A6M since they are much more well rounded aircraft. What do you do with the many IJNAF A6M groups? Train them, so that when you get sufficient numbers of N1K they are going to groups with 80 experience.
4. The best bases to defend are those that cannot be bombarded. The only base that this really takes into account is Clark Field. Sitting in the middle of the Philippines, Clark Field is your ideal air and land base. Build it up to maximum with your Engineers, and place as many tank heavy formations as you can. Pump the peninsula with as much supply as you can. When the allies land, they cannot destroy the LBA or weaken the LCU's with Ship Bombardments, they have to rely on air bombardment. Place one of your starting units with high numbers of AFV's there (2nd Guard, 1st, 2nd, 4th, 5th, 29th, 48th, 56th, 91st, 109th and notably the 2nd Tank Division). They will have to either starve you out, or send in as many LCU's as they can to capture the base.
5. Build up bases that you know you can hold. Building up a base, only to lose it to the allies really sucks. Strategically decide which bases you will have as naval/air stations, then send in Engineers to build them up. Make the allies have to build up their own bases.
6. Kamikaze's. Use only old aircraft for Kamikaze missions. Save at least one Ki-32 and Ki-51 airgroup for this purpose (since they now upgrade to the Ki-45 and Ki-102). You end up with about 3000 of these aircraft, and it would be a waste not to use them... Have your LBA punch a hold in their CAP (if you withdraw the A6M before they get slaughtered, good pilots in the N1K should be able to do this, even in late 1944) and send in your Ki-32/51 groups on Kamikaze. Some should make it through the Flak. You can do the same with the Ki-27 and Ki-43, since a Kamikaze will cause a heck of a lot of damage, no matter the actual fragility of the aircraft.
7. Keep the IJAAF out of the firing lines until good aircraft are in high numbers. After taking Malaya, Philippines and East Indies, keep the IJAAF out of harms way, so that you can build up your reserves of Ki-49 (for bombers) as well as train your airgroups up to at least 80 experience. It might be a good idea to hold off on destroying the USAFFE at Bataan, since they make good bomb targets. Get your Ki-32/51 groups up to high levels of experience, since they eventually change to Ki-45/102 Fighter Bombers. Do not switch Ki-27 to Ki-43, but bring all Ki-27 groups back to Japan and wait until you get some Ki-44/61 aircraft. Keep your Ki-43 groups of 80 experience around the Philippines, Siam, Malaya and the East Indies on garrison duties. When you get the Ki-44/61 change the Ki-27 groups over to this aircraft, and send them off to relieve the Ki-43 groups on garrison duty as well as the A6M groups on the frontlines.
***Production***
1. IJAAF production. The manual says not to tweak with production, or else you will suffer the consequences. However, it can really give you benefits later on. Once the Ki-44/Ki-61 appear stop all Ki-43 production (in fact, never EVER switch Ki-43 to produce Ki-43-II, every time you switch a factory, its prductivity goes down). Suffer with the Ki-43 until you get the Ki-44/61. Your best defence of a base is to have 1 FG of Ki-44/61 and 1 FG of Ki-45. The Ki-45 can really chew those Heavy Bombers up (where weaker planes get nailed) and the Ki-44/61 can get the fighters.
2. Produce the Ki-49 in massive numbers ASAP. Switch all Ki-21-II to Ki-49 (leave the Ki-48 production as is, then switch over to Ki-48-II which is just as good as the Ki-49). The Ki-49 almost doubles everything about the Ki-21-II except bomb capacity which remains the same.
3. Have Human Production on at all times. It is no good when the computer stops producing an aircraft that you really need to one that is sub-par.
***ASW Tactics***
Even though the Japanese are heavily out gunned in the Submarine conflict, you can do things to slightly minimize the damage.
1. Assign H6K and H8K Air Groups to bases along the Palambang-Nagoya Sea Route. Recon aircraft will attack Subs only at 50% of their range. Using these Long Range aircraft as ASW is your best option.
