Isn’t this an erosion of the silicon shield Taiwan is protected by? If they make semiconductors everywhere else then the world has less economic incentive to protect Taiwan from war.
Also, not sure why everyone forgets about it. People should have learned from the experience of the pandemic that the cutting-edge foundry nodes are not really the crucial ones, as being the bottleneck of industrial infrastructure. A delay of the next-gen iPhone or RTX gaming card isn't that catastrophic. But a shortage of embedded MCUs, which are actually fabricated by mature nodes, could stall the entire industrial base of a country.
Japan can't even sell arms to Taiwan right now. Even starting selling arms would be a huge change, let alone a mutual defensive pact.
It's extremely hard to change the constitution of Japan. It's the only constitution that has never been revised since WWII. LDP has been pushing this agenda for decades and nothing really happened.
It’s easy to ignore or work around it though, just like it routinely happens for every other constitution in the world.
The process to amend the constitution of Japan [0]:
1. two thirds of the house
2. two thirds of the senate
3. referendum
LDP just won the house. IF all LDP house representatives agreed with Takaichi then she could pass the first stage. Only two left!

In reality no such thing happened and one YouTube video of a handful of protestors doesn’t make it so.
What she did say is that a Chinese attack on Taiwan _could_ clearly become an existential threat to Japan. Note that key word _could_
Which… of course it could!
Japan hosts multiple US military bases. If it developed into an armed conflict between the US and China then it’s exceedingly likely that Japan would be attacked. Think Chinese missiles aimed At Yokosuka, just south of Tokyo.
Not only that but Japan and China have multiple territorial disputes. It’s not hard to imagine China deciding to go all in and settle those as well.
Or defending taiwan can be PR'd into a self-defending message.
She just won a super majority in the legislature that allows her to change the constitution.
But it will happen one way or another. Taiwan's Sovereignty is completely depending on one single country, the US. It's not like that Taiwan can just say no if the US demands more diversified chip production.
