There's just something about those older Japanese cruisers that makes them look more elegant than other vessels.
It might possibly be bcause of their long, relatively clean, deck lines. The superstrucure was quite compact, and except for the funnels, nearly nothing broke the main deck's profile. Their long, straight, and simple profile sometims reminds me of a sword. At least, those are my feelings about the Japanese 5.500Ton Cruisers family.

Ki-1 Class Submarine:

In 1918, what was truly left off from koko no Kaigun was the ability of operating Submarines, the fleet had none in it's inventory, while the IJN operated them since over twelve years. To fulfil Naval Construction Plans and to fill this void works began on a new shipyard complex specialized in Destroyer and Submarine construction located in the city of Kumoi, on Nintoku island. Design phase for the actual boats started shortly after.
Since for crews and workers the upcoming class would have been the first of it's kind to be operated and built the requirement called for a small, lightly armed unit whose purpose was to be mainly a training and experimental ship then a pure main-line one. All the expirience gained during thee building and operating processes would have been exploited for the coustruction of larger boats at a later date. The design that soon emerged was loosely based on the Japanese S2 Class but it was even smaller. Compared to the IJN Sub specs it called for a ship 47,3m long (instead of 58,6), 4,4m abeam (instead of 5,2m) with a surfaced draft of 3,3m. Top speed was planned to be 13,4 knots (instead of 16,5) surfaced and 9,5 submerged, endurance was to be 2020 nautical-miles surfaced and 60 submerged. Two 533mm bow-mounted torpedo tubes were to be carried (instead of the six 450mm ones of the S2 Type).
After the bilateral Agreements of September 1921 the plan went on: two units, Ki-1 and Ki-2, were funded and ordered in December 1921, and by the end of the year both had been laid down at the newly built (it had opened in mid-1920) Kumoi Arsenal. Untouched by the Washington Naval Treaty both units were launched by late 1922. Fitting-out dragged on more than expected, as pre-commissioning trials did, but ultimately both units were commissioned in 1924 and 1925, respectively.

Forming their own Sensuitai until 1929, when the newer and larger units of the Ki-3 Class started to enter service, both submarines ended up acting as test-beds for handling exercises, crew training and new systems sperimentation.
Ultimately their age and small dimensions exacted their toll: Ki-1 was decommissioned in 1938, Ki-2 in 1940. Both had been scrapped by the start of the Pacific war.


Ships in class: (laid down-launched-commissioned - fate)

Ki-1 1921-1922-1924 - Decommissioned 1938
Ki-2 1921-1922-1925 - Decommissioned 1940

No, ships, just an history walltext today. some parts might be a bit far-fetched but bear with me...

6.The Shi-Shi Kantai and the WNT (1921-1923)
Following the doctrine of Sato Tetsuharo, who argued that the Japanese Imperial Navy had to keep a strength of roughly 70% of the United states Navy, the Japanese Diet under Hara's government had funded a massive naval construction plan which called for the construction of eight Battleships and eight Battlecruisers. The plan, known as the Hachi-Hachi Kantai would have been relied on the Nagato-class Battleships already under construction, further augmented by the planned Tosa, Amagi, Kii and N°13 classes.
This massive plan was also conteplated by Koko as a guide for further naval constructions in a smaller fashion. Half of the size of the Japanese one it would have led to the building of six newer capital ships to be added to the already building Yagumo class, giving life to a smaller Shi-Shi Kantai (or four-four fleet), through which an optimistic aim of getting an almost 1:1 ratio with the US Navy was to be achieved by combining the two Navies strength, even surpassing the needs theorized by Sato.
All new constructed units were planned to carry the newer 409mm guns and to achieve maximum speeds than the Japanese Nagato class for commonality and easier integration between the Kokoan and Japanese squadrons.
After the Bilateral Agreements of 1921 the plan was retained and refurbished. Initially reconsidered as a Shi-Ni Kantai (four-two fleet) by leaving out the slower and lesser armed Yagumo Class it was soon brought back to a full Shi-Shi level by planning a fourth class of Battleships to augmented the three already planned. In sight of this, needed expansions of Toumachi Naval arsenal were underway since 1918, and two of the planned units were even allocated to the civilian Yamatogawa Shipyards in order to sped up construction.
The ambitious plan crashed to an halt on November 1921 when The Washington Naval Conference was called. During the conference a 5:5:3:1.75:1.75 ratio of tonnage between Britain, the United States, Japan, France and Italy was discussed, but for many, interminable, days of negotiations a figure for Koko was not reached. Koko delegation kept asking for a 5:2 ratio when compared to GB and the USA, obviously, neither of the two other delegations was willing to accept it as it would have give to a combined Koko-Japanese fleet effective parity with the royal navy and the US Fleet. The first request from the Americans was a 5:1 ratio, which in turn was rejected by Koko's delegation. Ultimately, a 5:1,25 ratio was achieved, after Koko no Kaigun agreed to scrap the two Nintoku Armored Cruisers and demilitarize the two Heian class Protected Cruisers. Overall, the 5:5:3;1,75:1,75:1,25 ratio was kept, with tonnage restrictions capped at 610.000t for the USN and RN, 366.000t for the IJN, 213.000 for the MN and RM, and ultimately 156.000 for KnK. The United States Navy was granted completion of two Colorado-class Battleships under construction, while the Royal Navy would have built two new ships. All future capital-ship construction was capped at 35.000t of standard displacement. Some specific ships whose tonnage exceeded the limit were allowed to be retained between existing and under construction units, namely two for the USN and RN, and one for each other signatories. France and Italy choose to not exploit this specific concession, as their finances did not allowed further expenditures at the time.
A loophole was thus created, as Koko delegation now pointed out, without the intent of backing up from their claim, that all planned units exceeded the allowed 35.000t limit, while there were no units under construction to fulfill the allowances. A solution was ultimately reached by allowing one of the Capital ships under construction in Japan to be transferred to Koko. In exchange of this, united states and Great Britain were granted completion of a further ship above 35.000t. the US Navy and chose to complete three units of the six Lexington-class Battlecruisers, Great Britain exploited that with Hood and the two G3-class Battlecruisers, whose construction had been started in October 1921 just before the Washington Conference had been called, Japan choose to complete Tosa, while koko no Kaigun would have received one out of Kaga, Akagi or Amagi. Another price to be paid for the capital ship transfer was that Koko was not allowed any tonnage for Aircraft Carrier construction. Other nations were instead allowed to convert two unfinished capital ship hulls into 33.000t Aircraft carriers, and to build new ones to a maximum displacement of 27.000, for a total of 135.000t for the USN and RN, 81.000t for Japan and 60.000t for France and Italy. Koko was also forbidden to exploit the around-30.000t of allowance left before 1927.
The Washington Naval Treaty was effectively ratified on February 6th 1922. In August of the same year a deal was made between Japan and Koko for the transfer of the Battlecruiser Amagi.

According to that data, I've granted 25.000 tons more for UK and USA, everyone else got less (CV tonnage is unchanged from reality, moreover Koko got none) and there are no Ottomans or Chinese fleets to be regulated. I've ended up with that figures by maintaining the original WNT ratio, just scaled it up a bit in order to get the extra ships I needed (more steel available for battles :P )


As a plus, under spoiler is Koko's fleet as of february 6th 1922, the day the WNT was signed.

Warning: huge image.
A special mention to Redhorse and his Republic of Texas AU,from which this sheet was inspired.


Next entries will cover some ships that got canceled by the WNT, then we will properly enter into the Treaty Era
