Massively cool cutting edge technology, even before Elon involvement. ;-)
There is also a huge amount of interesting videos on Youtube about these projects, all the way from the initial tunnel boring/blasting all the way to final outfitting (imagine installing rails & electric equipment in a 57 km long tunnel - no wonder it took 6 years of multi shift daily work, etc.).

But most impressive to me is this: [1] https://en.wikipedia.org/wiki/Seikan_Tunnel https://en.wikipedia.org/wiki/Seikan_Tunnel >>A 2002 report by Michitsugu Ikuma described, for the undersea section, that "the tunnel structure appears to remain in a good condition." The amount of inflow has been decreasing with time, although it "increases right after a large earthquake".
