Part 17: Reorganization and renewed priorities
The pacific islands garrisons are reinforced with heavy AA units and artillery when available. More artillery units will be constructed to cover all islands in the event of a war with the US.
However, all heavy artillery is stripped from the pacific islands and gathered in the Japanese mainland in preparation for offensive operations against fortified positions.
The Special Naval Landing Forces are already training and preparing for their next assignment.
By January 5th the marines are gathered and depart from newly conquered Siam towards the middle east. As part of this the landing craft flotillas are combined and reassigned the two heavy cruisers Aoba and Kinubasa as protection.
Two carrier groups accompany the marines, the first group with Hiryu & Soryu, the second with Kaga and Akagi. These carrier groups are the only two left operational while the rest are heading for Japan to be refit and have their screening forces upgraded if need be.
Both carrier groups are assigned the newest light cruisers from other ships prior to leaving Bangkok and will be expanded to three carriers according to the new naval doctrine as soon as possible.
Battleships will also accompany the invasion force but are currently limited by range due to poor range of the escorts.
We also do not want to strain our Italian allies ports in the middle east with the fuel required for battleship fleets. Therefore the battleships are based in Bangkok and from there they are moved west of India in preparation for port availability in the middle east.
January 6th war is declared on Iran. The target is their oil reserves and their strategic location in the middle east where we can mount later operations against the allies if we choose to enter the war. However, since they are not part of the allies we are still free to build up our forces and consolidate our position close to major oil reserves in case our relations to the Soviet Union should take a turn for the worse.
By January 9th the light carrier Hosho arrived in Suzaki for upgrades. A technical advisor describe the changes made to Kaga to bring her to fleet standard, similar changes will be made to Hosho.
"During her second reconstruction Kaga 's two lower flight decks were converted into hangars and, along with the main flight deck, were extended to the bow. This increased the flight deck length to 248.55 meters (815 ft 5 in) and raised aircraft capacity to 90 (72 operational and 18 in storage). A third elevator forward, 11.5 by 12 meters (37 ft 9 in × 39 ft 4 in), serviced the extended hangars. Bomb and torpedo elevators were modified to deliver their munitions directly to the flight deck. Her arrester gear was replaced by a Japanese-designed Type 1 system. A small starboard island superstructure was also installed.
Her power plant was completely replaced as were her propellers. New Kampon multi-stage geared turbines were fitted that increased her power from 91,000 to 127,400 shp (67,859 to 95,002 kW) during trials. Each had a high-pressure, a low-pressure, and a cruising turbine coupled to a single shaft. Her boilers were replaced by eight improved oil-burning models of the Kampon Type B (Ro) with a working pressure of 22 kg/cm2 (2,157 kPa; 313 psi) at a temperature of 300 °C (572 °F). The hull was lengthened by 10.3 meters (33 ft 10 in) at the stern to reduce drag and she was given another torpedo bulge above the side armor abreast the upper part of the existing bulge to increase her beam and lower her center of gravity as a result of lessons learned from the Tomozuru Incident in early 1934. This raised her standard displacement significantly, from 26,900 to 38,200 long tons (27,332 to 38,813 t). The lengthy funnel ducting was replaced by a single downturned starboard funnel modeled on that used by the Akagi with a water-cooling system for the exhaust gasses and a cover that could be raised to allow the exhaust gasses to escape if the ship developed a severe list and the mouth of the funnel touched the sea. The space freed up by the removal of the funnel ducts was divided into two decks and converted into living quarters for the expanded air group. The carrier's complement increased to 1708 crewmembers."

Completion date for Hosho is estimated to the 18th of January 1941.
January 12th battlecruisers Kongo and Haruna are also transferred from active duty to the fleet reserve where they will enter drydock as soon as possible for conversion to aircraft carriers in accordance with the new naval doctrine.
Light cruiser Tenryu, the oldest in the fleet is also sent to drydock for refitting with the latest equipment, new power plant, main armament and improved armor, completion date is expected to early May.
As can be seen here from one of our earlier light cruiser upgrades, the modernization requires extensive changes, but the work is performed significantly faster when compared to the work required on the larger carrier conversions and upgrades.
Portugals possesssions in the pacific and southern China has been a thorn in our side for long enough. However, our current levels of neutrality prevent us from taking action to secure our borders and remove these ulcers from the map.
Thus, the Imperial Japanese spying focus for 1940 will be to lower our neutrality so that we can work unhindered by diplomatic issues.
The primary target is the Macau region just west of Hong Kong. (another issue to be handled later...)
However, they also have possession just northwest of Australia that will make a good base for speeding up future expansion in the area.
Mid January Japanese scientists continue with breakthroughs in multiple areas, the latest include improvements to our electronic computation machines. This will help in many areas of research. The refocusing of research projects initiated late 1939 is already proving fruitful!
We are also receiving substantial contributions from our occupied territories and are currently approaching 70 points of leadership! By the 16th we receive word of a breakthrough in another key area, aero engines! This will enable us to test new prototype aircraft.
By January 17 our two carrier taskforces have arrived in the middle east and fighters from Soryu immidiately initiate air superiority missions over Iran. By 03:00 hours the first contact is reported with the Iranian airforce.
Initial reports from our flight leader Tsukahara over radio are positive, superior aircraft and tactics employed by the Empire of Japan will soon have secured air dominance!
