Hmm. China is installing a lot of renewables. A LOT. And although U308 has a far greater (very, very significantly greater) energy density compared to say, lithium, it also carries the stigma of Fukushima and other incidents, as well as political-career-destroying-potential in any democratically governed country (with an overhang in autocracies - Communist dictatorships - like China too).
I’d be surprised if uptake of nuclear is rapid in China due to their advanced (and accelerating) green policies, and also because they haven’t been prolific installers of nuclear in the past. Demand may force their hand, but by then they may have mastered large-scale renewables + batteries and won’t need it at all.
Re: Japan - I think you may find that demand for EV’s has been lacking there due to Toyota dragging it’s feet. Bit hard to join the revolution when you’re national manufacturer (and pride and joy) is reluctant. This article provides an interesting perspective:

PS Not to say there isn’t demand for U308 (and equivalents) elsewhere. And if the powers that be were smarter, they’d realize that nuclear power makes for a very clean alternative to even the cleanest renewables, and they’d consider it for our energy blend too.
