All this hoohaa from Japanese Press could just mean that FIRSTLY USMC F-35Bs will test out IZUMO modified for F-35B flight ops. Later (depending....) USMC may embark in a similar manner USMC F-35Bs aboard first deployment of QE 2021.
Marines Considering Flying U.S. F-35Bs Off of Japan’s Largest Warships
23 Aug 2019 Sam LaGrone

"THE PENTAGON – Officials in Tokyo have requested Marines deploy F-35B fighters aboard Japan’s largest warships, a U.S. defense official confirmed to USNI News on Friday. The service is now studying the feasibility of deploying short take-off vertical landing (STOVL) fighters from JS Izumo (DDH-183) and JS Kaga (DDH-184), Japan’s 24,000-ton big deck amphibious. [yep - not even USNInews can call these aircraft carriers 'aircraft carriers' or just (STOVL) 'carriers']… :roll:

...Prompted by the request, the Marines are now standing up groups to determine the technical feasibility of deploying U.S. F-35s from the two ships ahead of the Japanese Self-Defense Force F-35Bs being fielded. While the two ships were built with an eye toward STOVL fighter operations, the U.S. has to make an independent determination if their F-35s can operate on Izumo and Kaga.

For example, U.S. Wasp-class big deck amphibious ships have to undergo deck strengthening and have new heat resistant flight deck treatments as the Marines replace their AV-8B Harriers with F-35Bs. It’s unclear what additional work would be needed to make the two ships ready for F-35s. The Marines currently have an F-35B squadron forward-deployed to Japan — the “Green Knights” of Marine Fighter Attack Squadron (VMFA) 121 that operate with the Wasp Amphibious Ready Group as part of the 31st Marine Expediniaory[sic] Unit.

The Marines have charted out a similar relationship with the U.K. Royal Navy to deploy a squadron of F-35Bs from the new HMS Queen Elizabeth (R08) carrier for its first deployment.…"

South Korea Moves Toward Medium-Sized Aircraft Carriers: Why?
26 Jul 2019 Robert Farley

"What’s driving Seoul to include carriers in its naval expansion plans?

Earlier this week, South Korea announced its intention to include a medium-sized aircraft carrier in its naval expansion plans. The decision to construct the ships comes at a time of high tension with Japan, and takes place more generally in context of accelerated Japanese and Chinese aircraft carrier construction. Reportedly, the ship will displace 30,000 tons, making it somewhat larger than the Japanese Izumos. Designing the ship from the keel up to operate the F-35B may also remedy the need for the compromises that required extensive refitting in the Japanese ships.

Such a vessel would lock South Korea into the acquisition of the F-35B, except in the unlikely event that South Korea developed its own advanced STOVL fighter aircraft. The ROK has already agreed to acquire the F-35A, although it has also pursued a related project for a fifth-generation fighter. There is no indication that the KFX fighter would have STOVL capabilities, however. Presumably, the construction of this carrier would put to bed rumors about refitting the Dokdo-class to operate the F-35B, a plan that would have seriously strained the smaller vessels.

...The South Korean decision may provide additional ammunition to advocates of refitting the Canberra class amphibs (yet again based on the Spanish Juan Carlos) to carry the Joint Strike Fighter.

The timing of the announcement of the decision to build this vessel resonates uncomfortably with the renewal of tensions with Japan over World War II history, but competition with Tokyo probably remains mostly in the arena of prestige. This decision may also reflect increasing confidence that South Korea’s primary security problems do not involve North Korea. Fighters launched from carriers aren’t intrinsically worth more than fighters launched from land bases, although the presence of a carrier would complicate North Korean targeting problems. More likely, however, South Korea envisions using the ship in a blue water role, contributing to multi-national military and humanitarian operations, and safeguarding ROK interests in the distant abroad.

Whether this spurs additional construction on the part of Japan is an open, interesting question. Notwithstanding the diplomatic irritation that has resurfaced over the past months, Japan does not seem to regard South Korea as a meaningful security threat, or as a competitor for prestige. If happier relations return, the two navies could share lessons learned, and perhaps even act in concert to manage regional security affairs."

Word on the street: "Izumo/Kaga modification for F-35B costs" [total both]

"Refit costs announced today - 3.1 billion yet (just south of USD 300 million)." [i.e. 150 mirron US dorrar each]

More woids more believable perhaps however that depends on what is accounted for & when. More detail would be nice.
Here’s what Japan’s Defense Ministry wants to do with $50.5 billion
30 Aug 2019 Mike Yeo

"...The ministry’s request includes $1.08 billion for F-35s, which is made up of $291.3 million for three conventional takeoff and landing F-35As and $795.3m for six F-35Bs. These will be Japan’s first F-35Bs, and it’s expected the country will eventually order 42 "B" models, of which 18 will be acquired over the next five years, according to Japan’s Mid-Term Defense Plan released late last year. It also has plans to eventually operate 105 F-35As.

The F-35Bs are to be operated from two Izumo-class helicopter destroyers. Japan announced last year plans to convert both ships, which are currently designed to operate helicopters, to be able to handle F-35Bs. Notably, the budget request asks for $29.1 million for “partial refurbishment” to enable F-35B operations.

According to other reports, modifications for the ships include improvements to the heat resistance of their flight decks as well as the installation of additional lighting for aircraft operations. Japanese Defense Minister Takeshi Iwaya added that F-35B deck trials could be conducted with U.S. Marine Corps F-35Bs based in Japan following the modification work.... [why not have VX-23/ITF F-35Bs do the trial work on the modified Izumo Class?]

...Japan’s next fiscal year begins April 1, 2020. The budget request is not necessarily the actual amount that will be allocated by the Finance Ministry." [shades of the US wonky system]

So cheap. It makes you wonder if they weren't designed, at least partially, with this contingency in mind.

The Japanese Government/Defence Forces have admitted the IZUMO Class were designed with STOVL in mind/future use.

Hyundai to design F-35B-capable amphibious assault ship for ROK Navy
16 Oct 2019 Naval Today

"South Korea’s Hyundai Heavy Industries has received a contract to design the Republic of Korea Navy’s next-generation amphibious assault ship that would be capable of supporting short-takeoff and vertical landing fighter jet operations....

...According to a report from Yonhap, Hyundai is to deliver a conceptual design for a “large-deck” landing ship before exact specifications and technologies are determined. The work is to be completed by the second half of 2020.

In September 2018, Republic of Korea Marine Corps Chief, Lt. Gen. Jun Jin-goo, said the service was “considering building a LPX (large platform experimental)-type ship capable of carrying aircraft in close cooperation with the navy”.

The ship, which is planned to be put in service in the 2030s, will most likely operate the Lockheed Martin-built F-35B short takeoff and vertical landing version of the fifth-generation fighter aircraft. The country has a total of 40 F-35A (conventional takeoff and landing variant) aircraft on order under a contract from 2014...."
