Japan's Defence Minister publicly called for revising the Three Non-Nuclear Principles to allow introduction of US nuclear missiles, signalling the Takaichi administration's push to host US sea-launched cruise missiles (SLCM-N) from Japanese ports by 2032. The policy shift reflects Japan's response to Chinese and Russian nuclear expansion in the Asia-Pacific.

◆ The Wire takeaway

If you build systems that integrate with US naval platforms, Japan just opened a new port and budget line for nuclear-armed vessels. Yokosuka and Sasebo will need maintenance, logistics, and command-and-control infrastructure to handle US attack submarines by 2032—and that work is now politically possible.
