Under construction; reportedly being upgraded to include 4nm capability, with some reports of the completion timeline slipping toward 2029. Operator string normalised 17 Aug 2026: this row read "JASM (TSMC)" while Fab 1 at the same site read "JASM (TSMC / Sony / Denso / Toyota)". One joint venture spelled two ways, so Fab 2 resolved to TSMC alone and was missing from Sony's page and from the shared-site marking on the capacity statement that covers both fabs.
