Mining isn't the only bottleneck with rare earths. There also the processing, which is an industry China has monopolized through sustained investments over decades. They have also improved processing efficiency through investments in technology. It's going to take a while for anyone else to catch up.

I don't think this is the right way to characterize it. China invested when other countries didn't, but they didn't monopolize the market, they have no moat beyond expertise and some tech advancement that could be replicated easily enough. The only moat they have is related perseverance and other countries simply not wanting to put the work in.
I think they do have a moat because they dominate the supply chain not just in the raw material and processing but also in some of the actual technical experience, i.e. the experience of running such processing facilities, and also a monopoly on making the equipment that you need to build such a facility. They put export controls on those equipment and restricted their citizens who work in the rare earths industry from traveling aboard.
Basically, if we want to replicate what they did, we will have to do it mostly from scratch -- Japan and Australia has done some of the work already so it's not totally from scratch. It's obviously not impossible but it could take almost a decade for us to do that.
That said, I don't think this should be enough for Japan to stop investing in EVs. If Japanese car makers are really worried about this then they can build their plants in the US and leverage any deal the US has with China on real earths. They've already starting importing Japanese cars made in India and the US back to Japan so that's an established practice. Then once they've secured their own supplies they can make the EVs in Japan too. I think OP's point about the suppliers have more merit as a reason why Japan might not want to develop EVs.
I have worked with the Chinese REE industry, and we've often bumped heads and shared ideas together with them and I can confidently tell you, the Chinese don't use anything novel that has not been established in Western science already. What they do have is executing rarely-used techniques confidently at scale, but all of that is already often published in the West. The only reason the West hasn't done it is because these techniques are less profitable, and, surprise, the CCP actually forces processors to minimize ecological damage, which further bumps up the costs to the point only large-scale players can exist making such lower profits. You'll often find them using some obscure process alteration that was published minutely in the West.
As an addendum, companies in the REE Sinosphere are often encouraged by the CCP to exchange ideas with each other quite often, while Western companies often lock them behind proprietary patents and competition. While both systems have their pros and cons, the former allows for faster process proliferation (and a lower profit incentive for the innovator).

Moat is decades of process / tactic knowledge built by disproportionate amount of talent on geologic formations others didn't invest in. Right now they generate 15x mining graduates, university of mining tech alone enrolls more than all US mining programs combined. Then you throw all that into a mining city like Batou with 3 million people running vertically integrated operation. That's ecosystem scale with compounded advantages beyond "wanting" to put work in, it maybe scale on PRC has demonstrated ability to produce.
Between shallow kiddy pool and Mariana Trencth in terms of ease of replication, I wouldn't lean towards kiddy pool. I don't think "right way to characterize" their lead is "no moat" beyond... all the things that are actually, in fact very deep moats, as if any country can persevere their way to replicate decades of work and execute industrial policy of a 3 million large city dedicated to mining/rees.
I surmise, PRC will build out EUV (technical problem) and produce them at scale before west+co meaningfully tackles HREEs supply chain (technical and regulatory and industrial problem).
> they have no moat beyond expertise and some tech advancement that could be replicated easily enough
Incorrect, de facto, the only firms invested heavily in the rare earth refineries technology are Chinese for the last 20-30 years. Their moats are as deep as TSMC moats so to say.
> they have no moat beyond expertise and some tech advancement
See my sibling comment. Their moat is the scale and structure of their industry. Some parts of rare earth processing are dependent on that.
Processing is the thing china does, you don't really mine rare earths, they are in many areas. Sure there are substrates it's easier to extract from, but the massive pollution of the processing that china was willing to accept when others were not that allowed them to corner the market. It can be done more cleanly, the US has some processing for strategic reasons (not enough though), but doing it clean is _very_ expensive. Lets hope the people modifying plants to concentrate elements make work.
> an industry China has monopolized through sustained investments over decades.
Well, well, well, if it isn't the consequences of everyone's own inaction...
As I understand it, some of these processes also require a sufficiently large industrial base to be even remotely economical due to a reliance on industrial 'byproduct' (for want of a better word). Because of this, some of these processes are not something that can be quickly stood up in isolation over a few years. It would take concerted large scale planning over a long time period - something the Chinese system of government is almost uniquely capable of.
