There two main mine countermeasure exercises held in Japan every year. The first one is held in waters off Yokkaichi (near Nagoya) in the spring and this photo comes from the second one, on the waters of Mutsu Bay in the northern region of Honshu. They always look pretty impressive with lots of warships in one place at the same time.

The JMSDF has one of the msot active and best trained and equipped counter mine fleets in the world.

Overall, the JMSDF’s minesweeping fleet consists of 21 ships, and has gained international renown for its expertise in “sea clearance”.

Japan deployed five minesweepers to the Persian Gulf in 1991 to remove 1,200 sea mines laid by the Iraqi military in the waters off Kuwait.

During the opening stages of the Korean War (1950 to 1951), Japanese minesweepers helped clear landing areas from mines for American troops and also were engaged in operations further away from the shores of the Korean Peninsula in the Sea of Japan.

As stated, the exercise regularly, both alone and with the US.

Their new Uraga class of flotilla leader, Countermine support ships are 5,5000 ton vessels, and they are very effective leaders of counter mine flotillas. They have two of them:

My eyes are deceiving me or it realy LOOKS like 32 VLS cells (instead of 16 - a number mentioned a lot earlier) had been installed aboard new JS Asahi? Watch closely in HD from 3:45 mark on below video. It comes from the first (???) trial run of the vessel which should be delivered to JMSDF in March next year.

Supersonic Missile for the Mitsubishi F2

The terminal phase of the modernization of Japanese Mitsubishi F2 aircraft will soon begin with the qualification of a new supersonic anti-ship missile which will have to equip the aircraft from the end of next year.

Modernization of F2:


The first phase of modernization of the Mitsubishi F2 began in 2015 with the J / APG / 1 radar, which was modernized towards the J / APG-2 version. Although this radar already possesses the AESA technology, this one was not of the best performing, due to many limited functionalities and the lack of experience of the time. This update improves the power of radiation and signal processing and gives the F-2 a new ability to engage multiple targets.

Japan also equipped its F2 with a new AAM-4B missile equipped with an AESA-controlled radar head to enable active locking after its launch. This ability will allow the F-2 to leave the combat zone, or focus his attention on other targets after firing, instead of focusing on the target until impact (and remaining vulnerable).

Japan is modernizing its air force in a very tense context with North Korea, but also in preventing China's air and naval movements. This modernization should make it possible to extend the combative capability of the F2s who are in pairs with the F-15J while awaiting the arrival of the F-35. Designed to be a versatile aircraft, the F-2 carries a 20mm Vulcan gun, Mitsubishi AAm-3 air-to-air missiles and AIM-7F Sparrow.

The XASM-3


The final step is to integrate the new anti-ship supersonic XASM-3 missile developed by Mitsubishi Heavy Industries to replace the ASM-1 and ASM-2 missiles. In February 2017, an F-2 conducted a missile launch test as a precursor to a live fire. Serial production is expected to start in 2018. The XASM-3 is capable of reaching Mach 3 speed thanks to its ramjet engine powered by two air intakes (in the same way as the MBDA's Meteor air-to-air missile) . The XASM-3 flies close to sea level at the final stage of the attack to reduce the probability of detection and interception.

XASM-3 Basic Specifications:
Overall length: 5.25 m
Maximum speed: Mach 3 or more
Shooting range: 80nm (about 150 km) or more
Weight: 900 kg
Power: Integral Rocket Ramjet
Navigation and caller: inertial / GPS (intermediate step) + active / passive caller (terminal phase).

32 but only 16 with missiles in peace time/installed seems as had been said by Samurai and confirmed here

Asahi-class quasi-conspiracy Akizuki-class ship body, but receiving control books, reserved holders 4 pairs (32 pipes) MK-41 Vertical launch systematic volume, but half installed (16 pipes); then 12 pipes mounted vertical fire anti- [4], 4 Traffic ESSM.
(25DD)朝日級驅逐艦

So
16 cell's armed : 12 Asroc VL and 16 ESSM as Hyuga
or 32 : 16 and 64 as Akizuki

Japaness combattants have in general much cell's for ASW missiles the max for Atago 32 on 96 ! according Flottes de Combat or reliable sources ofc missiles load can change...
On the other hand even big DDG embark " only" a SH-60K or J the K is bettter armed also with small anti-ships missiles, used by the more modern classes, 91 ( 49 + 42 ) with 75 P-1/3C a robust ASW force !

And even if only 16 cell's host missiles in general with yet 4 Mk-41 installed they can get fast the war load, Europeans and i do face palm have provisions for majority of recent classes : Horizon/Type 45 : 16 cell's, De Seven Provincien : 8 etc... but we can wait for see it instaled ! ofc in relation with this part of the Asia which is since several years about 10 the main naval theater...

Yes, but the wiki article that you quoted cites an article from 8/2013 so it could be outdated. Even Japanese wiki quotes the same source with
一部雑誌等ではコスト低減のため、艦橋構造物前方のVLSは16セルという記述

もあったが、32セルとなっている
In a part of the magazines there was a description of 16 VLS cells installed in front of the forward superstructure to cut the costs (the link to the source I mentioned) but it became 32 (later on). How many missiles they will be loading (a mixture of ESSM and Type 07 SUMs) there in normal conditions doesn't matter as long as there's place to easily fill all of them. In the form that you mentioned (from 2013) it would have a place ready for additional 16 cells ready but not installed at all (those could be put there later on). And I think that with this material 32 cells are offcial contrary to what was proposed before the construction started.
