JP plays up China threat card for domestic politics/electioneering. It's theater. Here's how you know JP will seriously engage in TW defense, if they adopt any of the recommendations US think tanks believe is necessary to make US forces survivable in TW defense scenarios. Increase defense budget substantially, hosting US IRBMs, allowing US assets to spread out over other JP islands (agile combat deployment). Non of this is politically feasible, especially the latter since it expose JP population centres to PRC retaliation. For reference Japanese won't even allow US Aegis Ashore ABM to defend themselves against NK nukes.
