Tons of JMSDF weapons
SH-60J/K has Chaff and Flare. AN/ALE-47
JMSDF Akizuki-class has FAJ(Floating Acoustic Jammer) and MOD(MObile Decoy) and removed AN/SLQ-25 Nixie.
Akizuki, Asahi,Izumo, Maya-class has this system. (you can see that on each Wiki page.
The system is

As you can see, submarines also have MOD for self defence.
MOD is just beside 324mm HOS 303(Mk32).

Japan replaced some Mk46 by Type-97 LWT(so from 1997/DBID:314) and then Type-12(GRX-5) LWT(from 2012/NOT SSM). They replaces some ship( witch have HOS-303),all Aircrafts(P-3C, SH-60J/K and P-1) LWT. But They still have capable of Mk46 after the replacement.
Ships with HOS-303 are Hyuga-class, Akizuki-class and Asahi-class for now.
So can you change that?
Just for example of SH-60K using Type-97 or 12.

https://harpgamer.com/harpforum/topic/2 ... ment-53772 (here is forum of other game, but has correct info.)
Type-12 LWT is new Torpedo so No detail infomation even in Japanese.
Type-07 VLA system replaces RUM-139 VLA.Warhead is Type-97(2007-2012) or Type-12(2012-) LWT.
Akizuki, Asahi, Maya-class has Type-07, but Akizuki-class starts equip from DD-116 Teruzuki.
Improved range and using Type-97 and Type-12 for deeper and more silent target.

There not a lot of info, but you can find the name just above the "New Panch".
For correct info of Akizuki-class: This might help. You can DL the pdf file.

quotes from the pdf
The VLS also houses vertically-launched ASROC (Anti-Submarine Rocket) missiles.
The nominal outfit is sixteen missiles on the basis of one missile per cell. ASROC is a
lightweight torpedo deployed by a solid-propellant rocket that is fired towards the sea
area where a submarine detected by sonar is thought to be located. The torpedo
separates from the rocket when the target area is reached, descending to the sea by
means of a parachute. The torpedo operates as a homing weapon once it has been
launched into the sea. The JMSDF originally used the US Navy’s ASROC system but –
from Teruzuki (DD-116) onwards – has now standardised on an indigenous Type 07
torpedo-projection rocket. Similarly, the weapon deployed by the ASROC system is the
indigenous Type 97 torpedo.
Underwater Weapons:
The principal anti-submarine weapon deployed on the class is
the Type 97 lightweight torpedo. In addition to being utilised in vertically-launched
ASROC missiles, these can also be launched from triple HOS-303 mountings that are
located in both sides of the superstructure just forward of the first funnel. It can also be
deployed by an embarked sea control helicopter.
The Type 97 weapon will soon be replaced by the new Type 12 torpedo, which was
developed from the late 1990s onwards by the TRDI under the designation GRX-5.
The new torpedo has been specifically designed to have an improved performance in littoral
waters, where there is greater variability in areas such as temperature, water flow,
salinity and seabed shape. It retains the propulsion system and warhead of its
predecessor but incorporates a new sensor to deal more effectively with these
conditions. The signal processing capabilities of the guidance system have also been
improved.
And here is new of Asahi-class info.
http://www.navyrecognition.com/index.ph ... rials.html
For additional info for Asahi-class, that is specified for ASW mission. improved OQQ-24 sornar system and OQR-4 TACTAS. And equip FAJ and MOD for anti-torpedo system.
Using COGLAG(COmbined Gas turbine eLectric And Gas turbine) Engine type
https://navyrecognition.com/index.php/n ... royer.html
Asahi-class's OPY-1 radar is based on FCS-3A for Akizuki-class but removed LAD(local Air defence) function.
Newest Soryu-class sub, Oryu now remove AIP and lead-acid batteries and put Lithium-ion ons. This makes faster and bigger capasity size of the battery.

ASM-1C, I finally found reference,
http://www.mod.go.jp/j/approach/agenda/ ... 05/001.pdf (P14)
http://web.archive.org/web/201301241504 ... I50_07.pdf (P28)
Picture underthere is from above two.
You can see ASM-1C is same generation of SSM-1B.
And By the book Technical Research and Development Institute(TRDI) published, in Japanese but the part is saying
"なお、ASM-1C固有の機能である、ハープーンミサイルの最大射程以上の発射、"
"Further, ASM-1C's specific function, launch from longer maximum range of Harpoon missile,"
So ASM-1C's maximum range is 100nm, same as SSM-1B.
This is it for now.
