Semiconductors are again a focus of the Japan-U.S. alliance.

Unlike the first time this happened — in the 1980s and ‘90s when the two governments faced similar tension in the relationship — they are now a point of convergence and cooperation for the allies.

Tokyo and Washington are working together, bilaterally and in other forums, to build a stable semiconductor supply chain and ensure their continuing position at the leading edge of this critical technology. This trajectory is not guaranteed to continue, however. Enduring success requires partnership among all four players — governments and industry in both countries — which will ultimately rest on the political relationship and trust that they share.
