While that strategy might work for the domestic Japanese market at the moment, long-term it's a terrible strategy, as Japan automakers are losing significant market share to Chinese EVs in the EU, UK, Australia, Mexico, and SE Asia. Last month Honda and Nissan and Mitsubishi merged in an effort to save themselves. EVs from Honda, Toyota and Mazda are some of the dullest and least innovative EVs on the market, and way too expensive to boot. Their CEOs are arrogantly (and quite wrongly) claiming hydrogen and PHEV are the real future.
I live in SE Asia, I've only ever owned Japanese cars, my family has only ever owned Japanese cars for as long as I can remember - that is no longer the case. Japanese car dealerships are closing down countrywide and being replaced by dealers for Zeeker, Xpeng, MG, BYD and Neto. Even Japanese car factories in Thailand are closing down, only to be replaced by Chinese EV factories. Everyone is seeing the benefits of EVs and could care less whether the car comes from Japan or China - they want affordability, slick design, and an innovative and exciting driving experience - and Japanese cars are not offering any of that.
China will decimate the Japanese auto industry within this decade. Japan's economy relies heavily on auto exports. Japan is in for a world of hurt.
