As noted way down in this article, the Royal Navy plans to do away with its current MCM vessels by 2030, and while the decision is not firm, they may not be replaced by specialized MCM ships, but by perhaps the Type 31 frigates.
In addition to the LCS, the US Navy has ExMCM:
There has been a push for many decades now to make MCM more "integral" to an existing force, rather than having to bring in "outside" gear to deal with them. Notice how ExMCM units will be based on "vessels of opportunity." The Navy plans to test them off of a variety of different platforms, in hopes they are adaptable to many (even all) of them. This way, even a destroyer carrying such a team can be pressed into service to quickly clear a path through a field. The concept goes as far back as the US attempts to put a remote mine hunting system on a few Burke class DDGs.
This JMSDF ship fits this new emerging method. Nice that they have fitted it with specialist mine hunting sonar. Helpful, but--like other nations' ships in this new approach--they will be expected to sit outside the minefield, and control a remote robotic/autonomous force which actually goes in and clears the mines.
