Who is "we"? Japan doesn't have much choice, they either do things even though they are next to China, or ..what?

Maybe its time for people to stop being paralyzed by fear and invest in their future. If China is such a severe threat to Japan, then invest more in the JSDF. Yes, China is powerful and has an aggressive stance, but that's no reason to give up without a fight. Japan and South Korea together can very nearly match China's shipbuilding tonnage per year, and besides that Japan collaborates with America to develop advanced naval missiles like the SM-3 Block IIA. Effective deterrence of China w.r.t. Japan should be achievable if people stop overdosing on blackpills.

They already are investing in the JSDF. The JS Chokai is in San Diego right now being equipped with Tomahawk cruise missles, but AFAIK the plan is to equipped all 8 Kongo class destroyers with those missles.

And that's just one part of the expansion. But the short version is that the JSDF isn't staying a defensive only institution.

Nowadays, are large ships well protected from small unmanned underwater ships? Are they worth building?

		The large ships are well-protected. A “small unmanned underwater ship” has been a primary threat model for a century e.g. heavy torpedoes. These already have very long range and sophisticated sensors that allow them to hunt targets autonomously. The other side of this is that modern large military ships are almost literally unsinkable. It is very difficult to get enough explosive on target due to their extreme damage resistance. When the military does live fire exercises where they attack obsolete military vessels with no active defenses using torpedos, missiles, bombs, etc, they usually don’t manage to sink it. They have to send a specialized demolition crew afterward to actually scuttle the damaged ship and turn it into an artificial reef. An operational large military vessel will have layers of substantial active defenses that make this even more difficult.

		Yes to being worth building. The whole point of the navy is to be able to control waterways. The whole point of being able to control waterways is to be able to economically ship large amounts of material and people; in the case of warfare, soldiers, bullets, food, water, fuel, etc. An unmanned fast attack sub is going to be useless for defending your logistics fleet from strike fighters and anti ship missles. Even a dingy that has a guy in it with a rocket propelled grenade can send a cargo ship to it's grave. You have to have a surface ships with powerful defenses to protect them.

This is more of a humorous take. We already have trouble with one chip nexus is right next to China, and now we build another one? "ha ha". We is humanity. The collective we probably doesn't want a lever of the future controlled by a totalitarian communist ehnostate.

But yes, I agree Japan, Indonesia (as was intended), etc should wise up.

Your "whole humanity 'We'" isn't who's investing in chip industry in Hokkaido. It's Japan.

		But these things are done based on global supply chains. It's about more than just Japan, isn't it? Same time, Japan clearly wants freedom to do things its own way. Good. It has the freedom. It just has to take it. Do it.
