JASDF probably acquired or borrowed a simulator and potential pilots are probably training on them right now.
Once they had accumulated enough hours on the simulators they will probably go States side and test fly on the actual plane for 50 hours or so to achieve initial readiness.
A true interesting matter

Naval Today said:
The US Navy used two Burke class DDGs one a Flight I and the other a Flight IIA. These are very similar to the Japanese Kongo and Atago class AEGIS DDGs.
They also used an Akizulki class DDG, which was designed as an escort for BMD shooting JApanese AEGIS DDGs.
The exerciese also included an LA Class SSN< and a JSMDF Oyashio class SSK.
All of this was conducted in the Philippine Sea.
IMHO, they are working on ensuring that they can find and prosecute SSNs and SSKs in those waters.
They also did other exercises including the maneuvering drills and visit, board, search, and seizure (VBSS) exercises...but make no mistake, the ASW exercises and operations were the real focus of these exercises.
I will leave it to your imagination as to which SSKs and SSNs they were most concerned with in the Philippine Sea.
USS Decatur, DDG-73, Flight I Arleigh Burke AEGIS DDG
USS Spruance, DDG-111, Flight IIA Arleigh Burke AEGIS DDG
JMSDF Teruzuki DDG-116, Akizuki Class DDG
US Navy Los Angeles Class SSN
JMSDF Oyashio Class SSK
Those were probably some very intensive and serious exercises, and make pretty clear what the US and JMSDF policy is in the SCS should FON ever fail, or be militarily challenged.

New Japanese Defence Minister Inada. Nakatani demoted?
In early August 2016 Japan’s conservative Prime Minister Abe appointed a like-minded conservative as Defense Minister. She is Tomomi Inada.
It is too early to tell what impact she will have. She is considered highly nationalist by China and some other regional neighbors. Many political observers in Japan believe that Abe is grooming Inada to be his successor
So, has Nakatani been demoted? If so, was it due to not selling the sub to Australia?
Sub size and sonars
Gleaned from comments by ex-Vice Admiral, Masa Kobayashi (SHIPS OF THE WORLD, from 2016, No.9) along the lines that generally the larger the submarine the more powerful and effective its sonars. This places larger, reactor powered, submarines at the top of the sonar effectiveness tree (particularly for more commonly used passive sonars). The large SSKs, like the Soryu and future Shortfin, would rate highly. Small SSKs (eg. TKMS Ula class and Type 210mod) not so much.
SORYU TABLE (with earlier Oyashios) as of August 26, 2016
Higher cost for Higher Performance of Mark 2s (Mk 2s) 27SS and 28SS
The budgeting for the Japanese Ministry of Defence (MoD) is single year and multi-year depending on the documents. The Board of Audit (BoA) and Ministry of Finance (MoF) need to be convinced that ongoing or higher funding is needed for MoD's new submarine requests. The conceptual complexity of these requests is something MoD needs to constantly explain to MoF and to other relevant branches of Government.
The non-AIP Soryu Mark 2 (27SS onwards) and follow-on class will paradoxically have some structural similarities to the non-AIP Oyashios that preceded the AIP Soryu Mark 1.
The Oyashios themselves are undergoing life extension, including combat system upgrades, to bring Japan's operational submarine numbers up from the existing average of 16 up to 22 (to meet increasing strategic threats to Japan).
In the FY 2018 budgetary request, the Japanese Ministry of Defence (MoD) will request 76 billion Yen (0.99 billion AUD) for the first of the New Submarine Class.
In the FY 2018 budgetary request, the Japanese Ministry of Defence (MoD) will request 76 billion Yen (0.99 billion AUD) for the first of the New Submarine Class 29SS to be commissioned by the end of Fiscal year 2021. The new subs will be equipped with an improved sonar system and will be more silent/stealthy. The Japanese are also perfecting a new snorkel system that is effective in the higher sea states (eg, storms) that are common in the Pacific.
A competitive tender is applied for purchasing the diesel generator, because it is general equipment. In contrast, an optional contract can be applied for purchasing the snorkel generation system, according to related law [known as Cabinet Order on Budgets, the Settlement of Accounts, and Accounting (Chapter VII), Article 102-4. The suppler of snorkel generation system can select diesel generator as part, and consequently MoD can effectively exclude undesired diesel generator.
The MoD may explain the increased budgets for 27SS and 28SS to the Board of Audit (BoA), but BoA will not accept the increased budget [merely] due to the price of LIBs. If 27SS and 28SS are not equipped with the new snorkel generation system, the elastc sound reducing deck and new sonar system, the price of 29SS which utilizes these systems and new G-RX6 torpedoes will be nearly 80 billion yen..
Higher LIBs performance at higher cost
The new propulsion systems for LIBs-Soryus (<b>27SS</b> and <b>28SS</b>) are more expensive (1.1 billion yen) than those for LABs-Soryus (0.9 billion yen). TMEIC (Toshiba Mitsubishi-Electric Industrial Systems Corporation) won the competitive tender of the propulsion systems against the conventional supplier, Fuji Electric Co., LTD.
It is expected the new propulsion systems are much more powerful than those for LABs-Soryus. LIB Soryus 27SS and 28SS will have a higher maximum speed than previous Soryus (reliant on LABs). HAving said that, the top speed may not be dramatically because it would require a dramatically more powerful engine. You already note the logarithmic relationship of power to speed; this applies even more to the power of the engine than it does to the power storage capacity. High underwater speed in a D/E is only good for running away in a bad situation.
Nukes can use it to actually change theaters. D/E designs generally hit a wall of cost-vs-benefit at ~20 knots and I wouldn't expect this to change despite the switch to LIB vice LAB/AIP: fundamentally even a D/E with all its diesels going is generating an order of magnitude less energy than an SSN and they can afford to waste energy or likely even weight on a 25-30 knot capability.
Current Soryu Class Submarine
G-RX6 - Future Heavy Weight Torpedo
It is not clear whether the FY 2018 budget for the first of the New (post Soryu) Submarine Class includes the new torpedo, G-RX6, cost or not. If the cost of the G-RX6s is not taken into account for this budget request, this will present a budgetary problem. The 29SS, with G-RX6s, will be too expensive (eg. 80 billion Yen).
Judging from the budget status for development of the G-RX6, the development has nearly finished and <b>29SS</b> can be equipped with G-RX6s. It is expected the 29SS will show much superior performance to current AIP Soryu Mark 1s, but 29SS is 50% more expensive.
Japan is developing the Heavy weight [G-RX6] torpedo (HWT) for submarine, in order to oppose highly efficient surface warships and submarines. The HWT hass an advanced Torpedo counter counter measures (TCCM) function, and is excellent in detection, tailing, and the performance in deep and shallow ocean.
The TCCM capability reduces or eliminates the effect of enemy ship's or submarine's decoys and acoustic jamming. It is strongly assumed Japanese HWTs share technology with the US Mark 48 in TCCM and deeper/shallower performance.

oh really (emoticon of sarcasm):Now it looks like Spanish Alvaro de Bazan or Australian Hobart class.
... (it's from the most recent visit of F104 to Liverpool, UK):
...
A great teaser LOL, unbearable ! 
De Bazan is more small, an FFG but with a powerful armanent as a DDG, the more potents European combattant except Russians Kirov with 104 misssiles etc...

actually I've had the propulsion in mind: seems 25DD will get COGLAG and indeed look something like this:A great teaser LOL, unbearable !

I believe that's the first of the 25DD destroyers. Follow on, and more ASW centric. to the Akizuki.Now it looks like Spanish Alvaro de Bazan or Australian Hobart class.
I believe they intend just two of these.
Then next is the 27DD, which are the two new Atago AEGIS DDGs.
They will also soon be starting their DDR program, first one to be launched in 2021, which they will build quite a few of which will be what they call "the next generation destroyer escort class."
I believe they will begin replacing the Hatsuyuki and Asigir class DDGs, of which 12-13 ares till actie, but will begin to be replaced in that time period. Basically everything up to the Murasame class.
